What causes skin to be acne-prone?

A combination of genetic, hormonal, and environmental factors can cause acne-prone skin. One factor is excess sebum production by the sebaceous glands in the skin, which can clog pores. Hormonal changes, particularly androgens, can also increase sebum production. This is why acne is common during puberty, menstruation, pregnancy, and in conditions like polycystic ovary syndrome (PCOS). Another factor is clogged pores, whereby dead skin cells that do not shed properly can mix with sebum and clog hair follicles, forming comedones (whiteheads and blackheads). Bacterial growth in clogged pores and inflammation caused by this bacterium in the pores also play a crucial role in acne development, leading to redness, swelling, and pus. 

Additionally,  genetics can determine how much sebum your skin produces, how your skin cells shed, and your body’s inflammatory response, all of which can make you more prone to acne. Some studies also suggest that diets high in refined sugars and dairy products may exacerbate acne. Stress is another factor that can cause acne since it increases hormone levels that stimulate sebum production. Frequent touching of the face, wearing tight clothing, or using items like helmets and backpacks can cause further friction and pressure on the skin, leading to acne mechanica.

What is a good skin care regimen for someone with acne-prone skin?

A good skincare regimen for someone with acne-prone skin should focus on keeping the skin clean, reducing excess oil, and minimizing pore blockage without causing irritation. I always recommend a morning and evening skincare routine for my patients.

For a morning routine, start by using a gentle, non-comedogenic cleanser such as La Roche-Posay Effaclar Gel Facial Wash to remove excess oil and impurities. Using a toner is optional, but if you choose to do so, opt for one that is alcohol-free and contains soothing ingredients like witch hazel or glycolic acid to help exfoliate and remove any leftover impurities.

Next, apply a serum with active ingredients like salicylic acid, niacinamide, or tea tree oil to target acne. Niacinamide can also help reduce inflammation and control oil production. I like to recommend SkinCeuticals Silymarin CF to my patients. Use a lightweight, non-comedogenic moisturizer to hydrate the skin without clogging pores. Elta MD Moisture Seal is a moisturizer I typically recommend to my patients. Finally, apply a broad-spectrum sunscreen with at least SPF 30. Sunscreen is crucial to protect the skin from UV damage, which can worsen acne and cause hyperpigmentation. EltaMD UV Facial SPF 30+ Dry is a great sunscreen product I highly recommend. 

For an evening routine, start with cleansing the skin to remove makeup, sunscreen, and daily grime. Next, apply targeted acne treatments that can be stronger, like retinoids, which can promote cell turnover and prevent clogged pores. Finally, make sure to use a non-comedogenic moisturizer (same as your morning routine) to keep the skin hydrated. It’s essential even for oily skin to maintain the moisture barrier.

What ingredients should they look for?

Certain ingredients can help manage and prevent breakouts for acne-prone skin while keeping the skin balanced and healthy. Some ingredients to look for include salicylic acid, a beta hydroxy acid (BHA)  that penetrates pores to exfoliate and reduce sebum production, and glycolic acid, an alpha hydroxy acid (AHA) that exfoliates the skin’s surface to remove dead skin cells. For serums, look for niacinamide to reduce inflammation, retinoids to promote cell turnover, unclog pores, and reduce the appearance of acne and fine lines, and zinc to help control sebum production.

When it comes to moisturizers, look for hyaluronic acid to hydrate the skin without clogging pores, ceramides to restore and maintain the skin barrier, and aloe vera to soothe and hydrate the skin. For sunscreens, opt for non-comedogenic formulations specifically designed not to clog pores, as well as mineral sunscreens with zinc oxide and titanium dioxide that provide broad-spectrum protection with less risk of irritation. If you like to use mask treatments, look for products that include charcoal to draw out impurities and help detoxify the skin and clay, which helps to absorb excess oil and unclog pores. 

What ingredients should they avoid?

Avoiding certain ingredients that can exacerbate breakouts or cause irritation is crucial for someone with acne-prone skin. Avoid comedogenic ingredients like heavy oils and butters, waxes, and silicones that clog pores and contribute to acne formation. Additionally, steer clear of irritating ingredients such as alcohol and both synthetic and natural fragrances. You’ll also want to avoid harsh exfoliants like apricot and walnut shell powder. All of these ingredients can cause inflammation, irritation, and worsen acne. 

Product recommendations for acne-prone skin

For acne-prone skin, using products that help keep the skin clear without causing further irritation or breakouts is essential. The cleanser I typically recommend is the La Roche-Posay Effaclar Medicated Gel Cleanser. I like that it contains 2% salicylic acid to target acne and clear pores. For a serum, I like La Roche-Posay Effaclar Serum. For a moisturizer, CeraVe PM Facial Moisturizing Lotion is a non-comedogenic, oil-free moisturizer with niacinamide and hyaluronic acid. These ingredients will help to control oil. EltaMD UV Clear Broad-Spectrum SPF 46 is a lightweight sunscreen that protects against UVA and UVB rays. It is also formulated with niacinamide to help calm the skin. Differin Gel is an over-the-counter retinoid that helps prevent and treat acne by promoting cell turnover.

What is light therapy?

LED light therapy is also known as light-emitting diode therapy. This is a non-invasive skincare treatment that uses specific wavelengths of light to stimulate various cellular processes in the skin. It’s a popular treatment because it can help decrease inflammation in the skin. It can also treat a variety of skin conditions, including acne, fine lines, and eczema.

LED light therapy is a versatile treatment, with different colors of light offering a range of benefits for the skin. For instance, red light stimulates collagen production, reducing wrinkles and enhancing skin texture. It also aids in controlling inflammation and promoting wound healing. Blue light, on the other hand, targets acne-causing bacteria, effectively reducing breakouts. It’s a popular choice for mild to moderate acne treatment. Green light works to even out pigmentation and enhance skin tone while also providing a soothing effect. Lastly, yellow light promotes lymphatic flow, improving overall skin health and reducing redness and irritation.

What light kills acne bacteria?

Blue light therapy is the type of light commonly used to kill acne-causing bacteria. Specific wavelengths of blue light, typically in the range of 405 to 420 nanometers, are used to target and destroy the bacteria known as Propionibacterium acnes (P. acnes), which is a major contributor to acne.

Blue light therapy penetrates the skin and reaches the sebaceous glands where P. acnes bacteria reside. When exposed to blue light, the bacteria produce molecules called porphyrins, which then generate free radicals that ultimately destroy the bacteria. This process helps reduce inflammation and prevent new acne breakouts from forming.

Blue light therapy is often used as a non-invasive and drug-free treatment option for mild to moderate cases of acne. It can be administered on its own or in combination with other acne treatments. Depending on the severity of your acne and other individual factors, your provider may recommend other acne treatments. These can include over-the-counter skin care, prescription topical medications, oral antibiotics, birth control pills or isotretinoin.

How to choose the best acne light therapy device for you? 

Choosing the best acne light therapy device involves considering several factors to ensure it meets your specific needs and preferences.

Determine Light Type

First, determine whether you prefer blue light therapy, red light therapy, or a combination of both.

• Blue light targets acne-causing bacteria
• Red light reduces inflammation and promotes healing.

Some devices offer both types of light for comprehensive acne treatment. If possible, I would recommend getting a device that has both red and blue light to target both the acne and the inflammation that can cause hyperpigmentation.

Determine Design That’s Right For You

Consider the size and design of the device and whether it’s suitable for treating the areas of your skin affected by acne. Some devices are designed for spot treatments, while others cover larger areas like the entire face or back.

Next, check the intensity and wavelength of the light emitted by the device. Higher intensity and specific wavelengths are often more effective but may also increase the risk of side effects. Look for devices with adjustable settings to customize treatment intensity according to your skin’s sensitivity and the severity of your acne. 

Determine Desired Features

Additionally, opt for a user-friendly and convenient device to incorporate into your skincare routine. Consider factors such as portability, ease of setup, and whether the device is rechargeable or requires disposable batteries. To guarantee its safety and effectiveness, ensure that the device is FDA-cleared or CE-marked for acne treatment. Avoid purchasing unregulated or uncertified devices, as they may not provide reliable results and could pose risks to your skin. Make sure to research customer reviews and recommendations from reputable sources to learn about the experiences of other users with the device. Look for feedback on effectiveness, ease of use, durability, and customer service. Finally, compare the prices of different devices and consider the overall value they offer in terms of features, effectiveness, and long-term benefits. While investing in a high-quality device may require a larger upfront cost, it can provide better results and durability over time.

Ensure Eye Protection

It is very important to protect your eyes while using an LED treatment. If used incorrectly, LED light therapy has been shown to damage your eyes. At-home use can be safe if you follow the appropriate guidelines. Make sure to use a high-quality, reputable device that meets all safety standards, and be sure to read and follow the instructions and guidelines included. Some devices, as mentioned, only turn on when in contact with your skin, some are made to be used around the eyes with a lower intensity of light and have built-in safety features, while others may require eye protection. Make sure to research the right device for you.

Dr. Alexandra Bowles expands upon her insights on nail-strengthening habits from her recent Body Network feature: Nail Strengthening Habits for Thicker, Longer Nails

When it comes to strengthening your nails, incorporating certain habits into your routine can promote stronger, thicker nails and encourage healthy nail growth over time. Dr. Bowles shares 9 nail strengthening habits to incorporate into your routine. 

Maintain a Balanced Diet

For one, it’s important to maintain a balanced diet that includes essential nutrients such as protein, biotin, vitamins (particularly C and E), and minerals like iron and zinc, which are important for nail health.

Hydrate

Stay hydrated by drinking plenty of water to keep your nails hydrated and prevent them from becoming brittle.

Wear Gloves

Protect your nails by wearing gloves when doing household chores or working with harsh chemicals to prevent damage and breakage to your nails.

Avoid Acetone

Avoid harsh chemicals by limiting exposure to nail polish removers containing acetone, as it can dry out and weaken your nails. Opt for acetone-free formulas instead.

Moisturize with Hand Cream

Moisturize regularly by applying a moisturizing hand cream or nail oil to your nails and cuticles daily to keep them hydrated and prevent them from becoming dry and brittle. 

File Nails Carefully

Use a gentle nail file to shape your nails, avoiding harsh filing motions that can cause damage and weaken the nails. 

Take a Break From Nail Polish

Limit Nail Polish use by occasionally giving your nails a break from nail polish to allow them to breathe and recover. When using nail polish, opt for formulas free of harsh chemicals like formaldehyde, toluene, and dibutyl phthalate (DBP). 

Be Gentle with Your Nails

Be gentle with your nails by avoiding using them as tools for tasks like opening packages or scratching surfaces, as this can cause them to break or become damaged. 

Protect Them From Trauma

Protect your nails from trauma by being mindful of activities that can cause trauma to your nails, such as biting or picking at them or wearing acrylic tips, which can weaken and damage the nail structure.

Dr. Mona Foad expands upon the insights she shared in her recent Real Simple feature: Is Aloe Vera Good For Your Face?

Is it OK to use aloe vera on your face?

It is generally safe to use aloe vera on your face. It can have numerous benefits for the skin, including moisturizing, soothing inflammation, reducing acne, and promoting healing. Many skincare products contain aloe vera as a key ingredient due to its calming and hydrating properties. However, if you know you have very sensitive and reactive skin, I would recommend doing a patch test first. This allows you to ensure that you don’t have any allergic reactions or sensitivities to aloe vera. Apply a small amount of aloe vera gel to a small area of your skin (such as the inside of your wrist or elbow) and wait 24 hours to see if there’s any adverse reaction before applying it to your face.  If you are sensitive, applying aloe vera may cause redness, burning, or a rash. 

What are some of the key benefits of using Aloe vera on your skin?

Aloe vera has been around for centuries and has been used in many cultures for its healing properties.  The over 70 active components in aloe vera have many skin benefits.  It contains water, which helps to hydrate the skin without leaving it feeling greasy. It is also an excellent natural moisturizer, particularly for people with dry or sensitive skin. Aloe vera also has anti-inflammatory properties that can help to calm irritated or inflamed skin. For this reason, it can be beneficial for soothing sunburns, rashes, and other skin irritations.

Aloe vera contains salicylic acid, which has anti-inflammatory and antibacterial properties. This can help to reduce acne and prevent breakouts by unclogging pores and reducing inflammation. It promotes wound healing and can help speed up the recovery process for cuts, burns, and other minor injuries. It also contains compounds that stimulate the production of collagen, which is essential for repairing damaged skin tissue.

Aloe vera is rich in antioxidants, such as vitamins A, C, and E, which can help to protect the skin from free radical damage. This can reduce the signs of aging, such as fine lines and wrinkles. It has a natural astringent effect, which can help to tighten and tone the skin. This can help reduce the appearance of pores and give the skin a smoother, more refined texture.

What’s the best application method?

When it comes to the best application method for aloe vera on your face, this really depends on personal preference and the specific needs of your skin. One way to use aloe vera includes sourcing it directly from the plant itself. If you have an aloe vera plant at home, you can cut open a leaf and extract the gel directly from the plant. Apply the gel directly to your face as a moisturizer or soothing treatment. This method ensures you’re using pure, natural aloe vera without any added ingredients or preservatives.

Many skincare companies today produce aloe vera gel products specifically formulated for topical use. These products can include moisturizers, serums, masks, and cleansers. Be aware that they often contain additional ingredients such as preservatives, thickeners, or other beneficial compounds. Look for products that contain high concentrations of aloe vera gel and minimal additives.

You can also creating your own aloe products by mixing aloe vera gel with other natural ingredients, such as honey, coconut oil, or essential oils. DIY recipes allow you to customize the formula to suit your skin type and address specific concerns.  Always make sure to patch-test products to ensure you do not have a sensitivity. 

Who shouldn’t use Aloe Vera?

While aloe vera is generally safe for most people, some people may be allergic. If you have a known allergy to plants in the Liliaceae family (such as onions, garlic, or tulips), you may also be allergic to aloe vera. This is why performing a patch test before using aloe vera on your skin is important, especially if you have sensitive skin or a history of allergies. 

Even if you’re not allergic to aloe vera, it’s possible to experience skin irritation or sensitivity from its use. If you have very sensitive skin or any existing skin conditions, such as eczema or psoriasis, it’s a good idea to consult with a dermatologist before using aloe vera. 

For women who are pregnant or breastfeeding, the topical application of aloe vera gel is unlikely to pose a risk. However, oral use of aloe is not recommended in pregnant women due to a theoretical risk of stimulating uterine contractions. Oral aloe is also not recommended during breastfeeding as this has been known to cause gastrointestinal upset in nursing infants. In general, it is always best to err on the side of caution and consult with a healthcare professional before using it.

There are also some interactions with other medications. Concomitant use of aloe vera with topical steroids may cause increased absorption of the steroid cream. Oral use can lower potassium levels, so should not be used with digoxin, digitoxin, or furosemide and should be used with caution in patients using insulin or oral hypoglycemics.

How does this Aloe Vera compare to other ingredients?  

Aloe vera is a popular ingredient in skincare due to its hydrating, cooling, and soothing properties. While it is effective for many people, other ingredients can serve similar purposes. Hyaluronic acid is a humectant that attracts and retains moisture in the skin, helping keep it hydrated and plump. It is often used in moisturizers and serums to provide and maintain hydration.  

Niacinamide, or vitamin B3, is very popular in skincare. It promotes a healthy skin barrier by reducing moisture loss and dehydration and helps to calm skin with its anti-inflammatory properties. It helps with oil control and can also help with acne 

Cucumber extract is another ingredient known for its cooling and soothing properties, making it a popular ingredient in skincare products designed to calm irritated or inflamed skin. It also has hydrating benefits and can help to reduce puffiness and dark circles around the eyes. Calendula extract is derived from the marigold flower and is known for its anti-inflammatory and healing properties. It can help to soothe redness, irritation, and minor skin wounds, making it suitable for sensitive or damaged skin. Chamomile extract is another ingredient that has anti-inflammatory and antioxidant properties, making it beneficial for soothing sensitive or irritated skin. It can help to reduce redness and inflammation and promote overall skin health. Additionally, oat extract is rich in antioxidants and has anti-inflammatory properties, making it ideal for calming and soothing irritated or itchy skin. It can also help to improve skin barrier function and retain moisture.
