Ever feel that squeaky clean sensation after washing your face, only for it to turn into tightness and dryness? You can thank sulfates for that. You’ve probably spotted them on ingredient lists, but do you know what they actually do?
Sulfates are the reason your face cleanser foams so well, creating that satisfying lather we often mistake for ‘clean.’ The problem isn’t that they’re not delivering––it’s that they’re over-delivering, and your skin ends up paying for it. They can make your face cleanser too harsh, leading to redness, inflammation, dryness, or even allergic reactions.
But before we dive into the why, let’s first understand the what.

What Are Sulfates?
Sulfates are basically salts of sulfuric acid. You can find them in everything from face washes to shampoos, and even your laundry detergent (yes!). They are effective cleaning agents, sure, but effective doesn’t always translate to kind, especially when it comes to your skin.
Why They’re Used in Skincare
We all know that oil and water don’t mix well. Enter sulfates––the mediators break down the barrier between them and help them mix more easily. This makes them particularly effective at washing away dirt, oil, and pollutants from the skin.
With all the cleansing goodness of sulfates, it’s not surprising that they’re widely used in skin care products, especially cleansers and body washes. But they’re not always honest about their abilities. They’re like a gardener that prunes a little too enthusiastically—they’ll trim the weeds, but sometimes they take the flowers with them.
What They Do to Your Skin
1. Strip Natural Oils
Sulfates love to clean, but the problem is they don’t know when to stop. Not all oils on your skin are harmful. In fact, some are essential for maintaining its natural moisture. Sulfates in face washes and cleansers can strip your skin of these vital natural oils, leaving it overly dry and squeaky clean (which is not as good as it sounds).
2. Weak Natural Barrier
Those essential oils (sebum) that sulfates washed off? Turns out they are your skin’s unsung heroes. They support your skin’s natural protective barrier and prevent moisture loss. Without adequate sebum, your skin can become overly dry, leading to an imbalance in its protective barrier. When your skin barrier is compromised, moisture loss is inevitable, which, you guessed it, leads to even more dryness!
3. Compromised pH Balance
When your skin’s natural oils are stripped away, it sets off a domino effect. Consistent use of sulphate-heavy products can disrupt your skin’s pH balance, which weakens its protective barrier. This barrier serves as your skin’s natural defense against irritants and pollutants. Once compromised, it opens the door to issues like irritation, breakout, inflammation, redness, and acne, to name a few.
4. Skin Sensitivity
A disrupted skin barrier translates to increased skin sensitivity. Since your skin’s guard is down, it can no longer put up a good fight against irritants. This is especially troublesome if your skin is already sensitive. Increased sensitivity may manifest as itching, redness, burning, stinging, or even infections. So, if you have sensitive skin, you’re better off sticking to sulfate-free face cleansers that get the job done without treating your skin like it’s some kind of punching bag.
Sneaky Sulfates to Avoid in Skincare
There are a handful of sulfates that are often found lurking in skincare products, particularly in foaming cleansers. Next time you're shopping for a gentle face cleanser, scan the ingredients list for these red flags to avoid.
- Sodium Lauryl Sulphate (SLS)
- Sodium Laureth Sulphate (SLES)
- Ammonium Lauryl Sulphate (ALS)
- TEA Lauryl Sulphate
