Your Complete Guide To Caring For Sensitive Skin

It doesn’t have to be a pain

It is extremely frustrating to have sensitive skin—especially when you work at a magazine that covers all things beauty. One of the most fun things about this job is the sheer number of products NYLON staffers get to try, and when you have to avoid what feels like a trillion ingredients, it can definitely feel a bit like going into the best restaurant in the world when you’re allergic to half the items on the menu.

But these sensitivities have also made me somewhat of an expert (some might say obsessive) on all things skin care, and I now understand how to read and interpret the ingredients list on the back of the bottle, so that if I'm breaking out from a product, I can figure out why. And I want to assist you in doing that too. 

Read on for help diagnosing your sensitivities, to learn which popular ingredients can cause issues, and to see some of my favorite products that have proven to be safe and effective in treating my excessively reactive skin. 

But first: What is sensitive skin, and what causes it?
Simply put, it's skin that has some sort of reaction—whether it’s redness, increased dryness, stinging, or acneic breakouts—from particular ingredients. 

That said, sensitivity isn't a necessarily permanent condition. Having dry, dehydrated skin—meaning your skin is lacking in oil and water, respectively—can cause sensitivity in the hardiest of skins, but can be remedied with the proper moisturizing.

“The underlying cause of all these factors can be contributed to having a delicate moisture barrier that gets easily compromised,” says Austin, Texas-based esthetician Renee Rouleau. Your outermost layer of skin protects you against pollution, bacteria, and the other nasty particles we encounter in our day-to-day. However, when your skin is dry—which is to say, when that exterior moisture barrier isn’t working properly to protect your inner layers of skin—“it creates small, invisible cracks in the skin. Through these cracks, moisture can easily escape and irritants can enter more easily.” 

This is one reason why you might discover your skin is redder and more sensitive in the winter. The cold, wind, and super-dry air can all severely dehydrate your skin, leaving it more vulnerable to bacteria, pollution, and other irritants. 

How do you know you have sensitive skin?
This varies from person to person, but reddened skin, dryness, itchiness, flakiness, and breakouts that seem to occur after using specific products only are some of the signs. 

What are some common ingredients that cause reactivity and sensitivity? 

  • Fragrance is generally considered by dermatologists and estheticians to be the leading cause of skin sensitivity. This applies to both synthetic fragrance compounds, such as linalool and citronellol, as well as “natural” fragrances such as lavender, mint, and rose oils. It’s worth keeping in mind, too, that “fragrance” or “parfum” can mean any number of different undisclosed ingredients, so you don’t necessarily even know what it is when it appears on a label. 

  • Then there's alcohol. But be aware: Not all skin-care alcohols are created equal. If you’re experiencing excessive dryness or irritation, stay away from alcohol denat, SD alcohol, or isopropyl alcohol in a product. Because of the extreme drying effects of these compounds (think about putting rubbing alcohol on your face!), they should be avoided regardless of whether or not you typically experience sensitivity. 

  • Many of us know that foaming agents can be terrible for your hair, but sodium lauryl sulfate can be even worse for your skin. This ingredient raises the pH of your product and therefore your skin, causing dryness and irritation. 

  • Isopropyl myristate and isopropyl isostearate are thickening agents that can be comedogenic—meaning they can clog pores in some people. If you’re experiencing a breakout after introducing a new product, they could be the culprit.

  • That “tingly” feeling you get from using menthol, camphor, peppermint, and other “cooling” ingredients? In some people, that’s a sign of your skin getting actively irritated and inflamed. Use sparingly or not at all if you find they cause redness after use.

What to do if you’re having a reaction


1. First and foremost, determine as best you can what is causing the reaction and eliminate it from your routine. 

2. Temporarily cease using products containing harsh ingredients, such as alpha-hydroxy acids and retinol. Slowly integrate them back into your regimen as your skin returns to normal.

3. According to Rouleau, look for serums and moisturizers that include the below ingredients, which “mimic the skin’s natural lipids so they do a great job at barrier repair”:

  • Borage oil
  • Bois de rose oil
  • Carrot oil
  • Evening primrose oil
  • Cranberry oil
  • Niacinamide
  • Ceramides
  • Caprylic/Capric Triglyceride
  • Linoleic/Linolenic acids (this is not an exfoliating acid)
  • Phospholipids
  • Squalane
  • Tocopheryl Linoleate (vitamin E)
  • Tocopheryl Linoleate/Oleate (vitamin E)
  • Tocopherol (vitamin E)
  • Tocopheryl Acetate (vitamin E)
  • Phytosterols
  • Shea butter
  • Sunflower oil
  • Soybean oil
  • Safflower oil
  • Jojoba oil
  • Sweet almond oil
  • Canola oil
  • Sesame seed oil

4. Ditch any products with a high pH, which can dramatically change the natural pH of your skin and cause irritation. Products that make your skin feel tight and uncomfortable likely have a high pH, but if you’re unsure, I recommend emailing the customer service reps for the company that makes your products and bug them until they tell you the pH of the product in question. I’ve done this many times and was glad I did!

Now, here are a few of my favorite products

Cleansers
Cerave Hydrating Cleanser: I interviewed three people for this article—Soko Glam founder Charlotte Cho, dermatologist Dr. Heather Woolery-Lloyd, and Rouleau—and they all agreed that ceramides are one of the best ways to keep dehydrated, reddened skin at bay. This gentle cleanser is an excellent second step in my nightly routine, as it cleanses thoroughly but doesn’t dry out my skin.

Bioderma Sensibio Micellar Water: Many of French cult-fave brand Bioderma’s products contain fragrance, but this gentle micellar water is blissfully free of it and cleans and preps my skin for makeup in the morning without drying it out.
