Are AHAs Drying? The Truth About Alpha Hydroxy Acids and Your Skin
Alpha Hydroxy Acids (AHAs) are skincare powerhouses known for their ability to exfoliate, brighten, and smooth the skin. But one common concern among consumers is whether AHAs are drying. Since they work by loosening dead skin cells and increasing cell turnover, some believe they strip moisture from the skin, leaving it dehydrated.
Let’s break down this myth and uncover the real impact of AHAs on your skin’s hydration.
Understanding How AHAs Work
AHAs, like glycolic acid, lactic acid, and mandelic acid, are water-soluble acids derived from natural sources like sugar cane, milk, and fruit. Their primary function is exfoliation—removing dead skin cells from the surface, which can lead to a smoother, more radiant complexion.
Unlike harsh physical scrubs, AHAs work gently by dissolving the bonds between dead skin cells, allowing them to shed naturally. But does this process strip moisture from the skin? The short answer: No, not when formulated correctly and paired with hydrating ingredients.
AHAs and Hydration: The Science
Many people assume that exfoliation equals dryness, but AHAs are unique because they actually help the skin retain moisture when used properly. Here’s why:
1. AHAs Improve Skin’s Hydration Levels
AHAs, particularly lactic acid, are humectants, meaning they attract water to the skin. Rather than drying it out, they can increase hydration by pulling moisture into the outer layers of the skin.
Studies show that regular use of AHAs can improve the skin’s natural moisture retention by promoting the production of glycosaminoglycans (GAGs), which help the skin hold onto hydration.
2. They Strengthen the Skin Barrier
Contrary to the misconception that AHAs weaken the skin, they actually encourage the production of ceramides, which are essential for a healthy skin barrier. A strong barrier locks in moisture, preventing dehydration and irritation.
3. AHAs Help Skincare Products Absorb Better
By removing the dead skin layer, AHAs allow hydrating ingredients like hyaluronic acid, ceramides, and peptides to penetrate more effectively, enhancing overall skin hydration.
Why Do Some People Experience Dryness with AHAs?
If AHAs aren't inherently drying, why do some people experience tightness or flakiness after using them? Here are some possible reasons:
- Overuse: Using high concentrations of AHAs too frequently can lead to barrier damage, making skin more prone to dehydration.
- Lack of Moisture Support: AHAs work best when paired with hydrating ingredients like hyaluronic acid, glycerin, and ceramides.
- Skipping Sunscreen: AHAs can make skin more sensitive to UV rays. Without SPF, sun damage can lead to moisture loss.
- Using Alcohol-Based Formulas: Some AHA products contain drying alcohols, which can strip the skin and cause irritation.
How to Use AHAs Without Drying Out Your Skin
To get the most out of AHAs without compromising hydration, follow these best practices:
✔ Choose a Balanced Formula: Look for AHA products that contain hydrating and soothing ingredients, like ceramides, sodium PCA, Shea and peptides.
✔ Start Slowly: If you're new to AHAs, use them 2–3 times a week and gradually increase as your skin builds tolerance.
✔ Follow with Moisturiser: Always apply a hydrating moisturiser after using AHAs to reinforce your skin barrier.
✔ Use Sunscreen Daily: AHAs make skin more prone to sun sensitivity, so SPF is non-negotiable to prevent moisture loss and irritation.
