Glycolic Acid for Better Skin and More Collagen Production?


Glycolic acid -

Glycolic acid is a natural and highly effective way to exfoliate or refine the skin. Maybe you’ve heard of a glycolic peel or even experienced one before.

When used topically, this natural acid helps to remove dead skin cells, which can benefit many common skin concerns from acne to wrinkles (and many others in between).

This acid works by breaking the bonds of those old, no longer needed skin cells which can clog up pores and make the skin look dull.

After using this acid, many people report a more revitalized, glowing appearance.

What Is This Acid?

Both alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are commonly used in skin care products today. The BHA most widely used in cosmetics is salicylic acid.

Common AHAs used in cosmetics include glycolic, malic, and lactic acid. As an AHA, glycolic acid is considered to be an “effective active compound” in the skincare world.

So what is this acid? It’s a colorless and odorless alpha hydroxy acid, which is typically derived from sugar cane.

Its chemical formula is C2H4O3. Glycolic acid can also be created synthetically.

What is this acid structure like? It’s considered a hygroscopic (it readily takes up and retains moisture) crystalline solid.

This acid is the smallest of the AHAs, and it also has the most simple structure. The small-sized and straightforward molecules are said to easily and readily penetrate the skin.

In beauty products, you’ll often see glycolic acid as a percentage.

For example, glycolic acid 10% means that 10 percent of the formula is glycolic acid. A higher percentage says it’s a more robust glycolic acid product.

Benefits for Skin

In general, this acid works as a skin exfoliant that helps to remove the outer, dead skin cells. It can also help to get rid of excess oil.

As an active skincare ingredient, it can speed up the skin renewal process and improve the texture as well as the appearance of skin.

Dermatologists and estheticians may recommend this acid for the following skin concerns:

Also, to improving this wide variety of skin-related problems, glycolic acid can increase collagen production.

According to Kenneth Howe, M.D., a dermatologist at Wexler Dermatology in New York City, “Glycolic acid stimulates fibroblasts in the dermis to produce increased amounts of collagen,” says Dr. Howe.

Why is this a good thing? As we age, our body’s collagen generation naturally slows down, so a boost to production can equate to a more youthful appearance, including firmer, smoother skin.

How to Use

Just like with other exfoliating products, you should start small and see how your skin does with this AHA.

If you have sensitive skin, it’s even more important to be careful or check with your dermatologist before using it at all.

A cleanser containing glycolic acid can be an excellent way to test out this skincare ingredient for the first time.

Once you know you do well with a cleanser, then you can move on to other products if you like.

You can also start with a lower percentage of glycolic acid products to see how your skin reacts.

Are there more glycolic acid toner benefits with a higher percentage? In general, a more top percentage product can equate to more obvious or faster effects, but it also increases skin sensitivity more.

This is why a robust glycolic acid peel is often done under the supervision of a professional, and it’s not done too frequently (once a month, for example).

What are some of the potential glycolic acid products you may want to consider for your skincare routine? Options include:

  • acid face wash
  • acid toner
  • acid pads (another way to use this AHA acid as a cleanser/toner)
  • acid cream
  • acid lotion
  • acid peel

Glycolic acid products are typically recommended for people with healthy, oily, or combination skin.

If you have dry or sensitive skin, you may not do well with glycolic products, so check with your dermatologist before using it.

Risks and Side Effects

What are the side effects of this acid? As with other AHAs, it can increase your sensitivity to the sun. It’s essential to wear sunscreen after using any type of AHA to avoid a sunburn.

It’s often recommended to only use products containing this acid at night, so read products carefully and check with your dermatologist or esthetician on how to best use glycolic acid most effectively for your skincare goals.

Discontinue the use of a glycolic product if irritation occurs. Sometimes, a lower percentage of acid may also be necessary if you find a product is too strong.

Final Thoughts

  • Along with malic and lactic acids, glycolic acid is a type of alpha-hydroxy acid or AHA.
  • Of the AHAs, glycolic has the simplest structure and is the smallest in size, which contributes to its ability to penetrate and benefit the skin quickly.
  • If you’re wondering how to use this acid, some of the options include a toner, face wash, face mask or peel.
  • The best acid products use glycolic acid derived naturally from sugarcane and contained other beneficial natural ingredients.
  • Using this acid for common skincare complaints like acne or wrinkles can be highly effective because this acid helps to remove clogging dead layers of skin and reveal the more youthful skin underneath.
  • This acid is typically recommended for people with normal, oily, or combination skin.
  • Always read product label directions carefully and wear sunscreen after using products containing AHAs to avoid sunburn.
