Skincare products can help your skin look and feel great, but can excessive use or using the wrong products for your skin damage your skin barrier?
Today, I’m excited to share my insights on how skincare products can affect our skin barrier – a topic that’s both complex and crucial for anyone serious about their skincare routine.
Understanding the Skin Barrier
The skin barrier, also called the stratum corneum, is like a shield that protects your body from things like dirt, germs, and harmful UV rays. It’s super thin, only 10-30 micrometers thick, but it’s very important for keeping your skin healthy.
The skin barrier looks like a brick wall. The “bricks” are tiny dead skin cells called corneocytes, and the “mortar” that holds the bricks together is made of special oils called lipids, which include ceramides, cholesterol, and fatty acids.
This brick wall keeps water from leaving your body and helps stop harmful stuff like bacteria and pollution from getting in.
Tip: This should be a good indication that skincare products containing some or all of these ingredients (ceramides, cholesterol, and fatty acids) can help to strengthen your skin barrier.
The Importance of pH Balance
One important thing for keeping your skin barrier healthy is making sure your skin’s pH is balanced. Your skin’s natural pH is a little bit acidic, usually between 4.5 and 6.5.
This acidity helps keep a healthy balance of good bacteria on your skin, which is important for skin health.
Some skincare products, like soaps and cleansers, can mess up this balance, which can make your skin barrier weaker.
Tip: When picking skincare products, it’s important to choose ones that are pH-balanced to keep your skin’s natural acidity just right.
The Double-Edged Sword of Exfoliation
Moderate exfoliation can reveal brighter, smoother skin by removing dead skin cells. However, over-exfoliation is a common problem that can seriously compromise the skin barrier.
Physical scrubs and harsh chemical exfoliants can strip away too much of the protective layer, leading to increased sensitivity, dryness, and even inflammation.
To avoid this, it’s important to choose gentle exfoliants and use them sparingly. For most skin types, exfoliating once or twice a week is sufficient. It is important to listen to your skin. If you find that your skin starts to get itchy or has a burning sensation after using an exfoliant, it’s time to stop for a few days.
Over-exfoliation can damage your skin barrier, leaving you with more skin problems than you started with.
Gentle chemical exfoliants can work better than scrubs if you have sensitive skin.
Tip: If you have sensitive skin, you might want to exfoliate even less often.
The Hydration Dilemma
Keeping your skin hydrated is super important for a healthy skin barrier, but it’s not always as simple as it sounds.
While your skin needs moisture, putting too much water on your skin can actually stop your body from making its own natural moisture. This can make your skin depend more on lotions and creams.
The trick is to find the right balance.
Tip: Look for products with ingredients like hyaluronic acid or glycerin, which pull water into your skin. You also want products that help keep that moisture locked in, like ceramides or fatty acids.
Occlusives and Emollients: Friends or Foes?
Occlusive ingredients, like petrolatum (petroleum jelly) and certain oils, form a layer on your skin that helps keep moisture in and stops your skin from losing water. Emollients, like ceramides, cholesterol, and fatty acids, help fill in the spaces between your skin cells, making your skin barrier stronger.
While these ingredients can be really helpful, using too much of them might cause problems. For example, too many occlusive products can trap bacteria on your skin, which might lead to pimples, especially if you have oily or acne-prone skin. CeraVe as a brand is known for their use of ceramides in their skin care product as well as the way they promote skin barrier health.
What’s the best approach? Use these ingredients wisely.
If you have dry skin, you might want to use more occlusive products, especially before bed.
If you have oily skin, it’s better to use lighter products that won’t clog your pores.
Tip: Know your skin type before deciding which product is best for your skin.
The Active Ingredient Challenge
Many popular skincare ingredients, like retinoids, alpha-hydroxy acids (AHAs), and vitamin C, are known for helping improve skin texture, reduce wrinkles, and brighten your skin. But these powerful ingredients can sometimes hurt your skin barrier if used too much or in high amounts.
To get the benefits of these ingredients without damaging your skin barrier, start with small amounts and slowly increase how much you use as your skin gets used to them. It’s also a good idea to use them on different days or at different times.
For example, you could use vitamin C serum in the morning and retinoids at night instead of using them both at the same time.
Tip: You can also look at Vitamin C serums that have a lower concentration when you introduce them to your skincare routine.
The Microbiome Connection
Recent studies show that the skin microbiome, which is the collection of good bacteria on your skin, plays a big role in keeping your skin barrier healthy. Some skincare products, especially those with ingredients that fight germs, can mess with this balance.
But now, there are skincare products with probiotics and prebiotics that help support the good bacteria on your skin. These products work to keep the right balance of bacteria, which helps keep your skin healthy and strong.
Tip: You should try to eliminate all bacteria from your skin. There are good ones that are needed to protect your skin barrier. Over-sanitizing is also bad for your skin barrier as it removes all bacteria, not only the bad ones.
Environmental Factors and the Skin Barrier
Skincare products don’t work alone—things like pollution, sunlight, and the weather can all affect your skin barrier.
It’s important to change your skincare routine depending on these outside factors to give your skin the best protection.
For example, if you live in a city with a lot of pollution, you might want to use products with antioxidants to protect your skin from damage. If you live in a dry area, you’ll want to use more products that hydrate your skin and lock in moisture.
Tip: Seasonal changes can also play a role in the health of your skin barrier, and you might need to have different skincare products, for example, in winter than in summer.
5 Ways to Build a Skin Barrier-Friendly Routine
Now that we understand how different factors can impact the skin barrier, let’s look at how to build a skincare routine that supports and protects this vital structure:
1. Cleansing
Start with a mild, pH-balanced cleanser to keep your skin’s natural acidity in balance. Avoid using hot water to wash your face as it can strip your skin’s natural oils.
2. Drying
This might sound a bit far-fetched, but recently I discovered how traditional face towels can harbor bacteria that can disrupt the skin barrier. Pat dry after cleansing and avoid rubbing your skin with a bacteria-free solution.
2. Toning (Optional)
Use a hydrating toner or essence right after cleansing to add moisture back to your skin. Choose alcohol-free products that have moisturizing ingredients like hyaluronic acid or glycerin.
3. Treatment
Use serums with active ingredients carefully and start adding them to your routine slowly. More isn’t always better when it comes to active ingredients.
4. Moisturizing
Finish with a moisturizer that has barrier-boosting ingredients like ceramides or fatty acids. Complete your routine with a moisturizer that contains barrier-strengthening ingredients like ceramides or fatty acids.
5. Sun Protection
Finish your routine with broad-spectrum sunscreen during the day to protect your skin barrier from UV damage. UV rays can seriously weaken your skin barrier, so this step is really important.
5 Things to Avoid when Using Skincare Products
When it comes to skincare, there are several common mistakes that can compromise the skin barrier:
1. Over-exfoliation
As mentioned earlier, exfoliating too often or using harsh products can hurt your skin barrier. Stick to gentle exfoliation 1-2 times a week.
2. Using too many active Ingredients
It might be tempting to try every trendy new ingredient, but using too many powerful products at once can overload your skin. Add new products one by one and give your skin time to get used to them.
3. Neglecting moisturizer
Even if you have oily skin, moisturizer is important for keeping your skin barrier healthy. Look for a lightweight moisturizer that won’t clog your pores if you’re prone to breakouts.
4. Hot showers
Even though a hot shower feels nice, it can take away the natural oils in your skin, which can harm your skin barrier. Try using lukewarm water instead.
5. Ignoring your skin type
What works for someone else might not work for you. Understanding your skin type and its specific needs is crucial for maintaining a healthy skin barrier.
When you start using new skincare products and notice any irritation, redness, or sensitivity, it is best to stop, alternate, or exchange for something else.
Your Skin Type and Your Skincare Routine
Your skincare routine should be flexible enough to adapt to different scenarios:
Oily Skin: Use lightweight products that won’t clog your pores. A clay mask once a week can help control extra oil without drying your skin out.
Dry Skin: Look for thicker, moisturizing products. Adding facial oils or balms, especially at night, can help keep your skin soft.
Sensitive Skin: Choose gentle, fragrance-free products. Micellar water can be a good option for cleaning your skin without irritating.
Alternation in Climate and Your Skincare Routine
Humid Climate: You might not need as many thick products. Focus on lightweight, hydrating layers to keep your skin fresh.
Dry Climate: Make sure to keep moisture in your skin. Using a humidifier and thick moisturizers can help.
Seasonal Changes: Be ready to change your routine with the seasons. You might need a richer moisturizer in the winter and a lighter one in the summer.
Advanced Techniques for Skin Barrier Support
Once you’ve mastered the basics of skin barrier care, you might want to explore some more advanced techniques:
Layering: The Korean skincare technique of layering many lightweight, hydrating products can be great for supporting the skin barrier. Start with the thinnest products and work your way up to the thickest.
Facial Massage: Gentle facial massage can help improve circulation and promote lymphatic drainage, potentially supporting skin barrier function. Just be sure to use clean hands and a facial oil to prevent tugging on the skin.
Sheet Masks: Used occasionally, sheet masks can provide an intense boost of hydration to support the skin barrier. Look for masks that contain ingredients like hyaluronic acid, ceramides, or niacinamide.
Overnight Treatments: Night is when our skin goes into repair mode. Using an overnight mask or a richer night cream can provide extra support to the skin barrier while you sleep.
The Role of Diet in Skin Barrier Health
While topical skincare is important, what we put into our bodies also plays a crucial role in skin barrier health. A diet rich in omega-3 fatty acids, found in foods like fatty fish, flaxseeds, and walnuts, can help support skin barrier function from the inside out.
I recently came across an omega-3 fish oil product that has a lemon flavor, though subtle it is great to use for children as well as adults. It not only helps your skin barrier but also enhances brain function.
Antioxidant-rich foods like berries, leafy greens, and green tea can help protect the skin from free radical damage, indirectly supporting the skin barrier. And staying hydrated by drinking plenty of water is crucial for overall skin health.
Putting It All Into Practice
Understanding the skin barrier can feel overwhelming, but it doesn’t have to be. Start by simplifying your routine to just the basics – a gentle cleanser, moisturizer, and sunscreen.
Pay attention to how your skin feels and looks.
Then, gradually reintroduce your other products one by one, noting any changes in your skin. This can help you identify which products are truly benefiting your skin barrier and which might be causing issues.
Skincare is a personal journey. What works for someone else might not work for you, and that’s okay.
The key is to listen to your skin and adjust your routine accordingly.
