Of all AHAs, glycolic acid is the most popularly used, and you can find them in so may over-the-counter products such as lotions, creams, serums, peels, cleansers and toners. This content gives a deep dive of everything you need to know about glycolic acid for skin, keep reading to learn more.

What Is Glycolic Acid?

Glycolic acid is an AHA family (alpha hydroxy acids). It’s the most common and widely used skin exfoliating acid, it’s derived from sugar plant. Glycolic acid is known for its small molecular size in weight which enables it to penetrate deeper into the skin to eradicate dead skin cells and dissolve sebum. According to Kenneth Howe, M.D., a dermatologist at Wexler Dermatology in New York City “Of all the AHAs, glycolic is the simplest in structure and the smallest; it has the lowest molecular weight”. That small molecular weight means “it’s easy for it to penetrate your skin and be super effective,” says Alix Shapiro, skin therapist at Heyday in NYC.

Benefits Of Glycolic Acid For Skin.

Reduces Wrinkles & Fine Lines.

Because of its skin-exfoliating and skin-renewing potentials, it is often used in anti-aging products. It can help smoothen fine lines, wrinkles and improve the skin’s tone and texture, as it stimulates collagen production, accelerate cell turnover and regeneration, thereby refining the skin texture making it look firmer, plumper and smoother. These research studies [1, 2] justifies the fact.

It Fades Hyperpigmentations.

As a skin exfoliator, glycolic acid fades hyperpigmentation and skin discoloration by sloughing off the dead skin cells at the top layer of the skin, thereby encouraging the departure of dead skin cells with melanin which in turn addresses minor hyperpigmentation issues such as dark spots, acne scars and melasma. A research study validates the fact.

Helps Boost Hydration.

Just like lactic acid helps hydrate the skin and hold unto moisture, glycolic acid helps boost skin hydration levels. Studies also show that glycolic acid significantly increases skin’s hydration. It does this by helping skin make substances like mucopolysaccharides, which help skin stay hydrated by increasing its natural content of hyaluronic acid, which in turn enhances skin’s resilience.

It Brightens The Skin.

Using glycolic acid regularly can help brighten the complexion. When the dead skin cells are being gently stripped off, a fresher, healthier and more brighter skin reveals, which improves your overall skin tone.

It Exfoliates The Skin.

Glycolic acid is an exfoliant, it has small molecular size which enables it penetrate easily to exfoliates both skin surface and beneath. It helps shed dead skin cells and reveal the newer, brighter layers underneath. [3]

Minimizes Large Pores.

If you’re struggling with visible large-pores especially if you have an oily skin, then glycolic acid can come to your rescue. Alpha hydroxy acids in general (which includes glycolic acid) can have a retexturizing effect on the skin. Using products that contain these ingredients can help to reduce the appearance of enlarged pores by helping to sweep away dead skin cells, oil and other debris that has built up inside pores and on the skin’s surface.

In one study, 22 Japanese women applied a 30% concentration glycolic acid solution every 2 weeks for a total of 5 treatments. More than 70% of participants saw improvement in enlarged facial pores. Specifically, visible pores were improved by 34.6%, open pores by 11%, and dark pores by 34.3%. Another study found improvement in facial pores by 28.3% with a 40% glycolic acid and vitamin C formulation.

Reduces Acne.

Glycolic acid can help reduce pesky blackheads, whiteheads and acne breakouts scattered all over your face, due to its mild exfoliating and acidic nature, when applied on the skin — glycolic acid weaken the “glue” that holds dead skin cells together, penetrates deeply into the skin to decongest the pores from pore-clogging impurities and oil build-up, thereby encouraging the healing of acne and also preventing future occurrence. A clinical research study carried out on Asian skin proved that, glycolic acid had better responses for noninflammatory lesions than for inflammatory lesions, with sebum levels significantly reduced.

How To Use Glycolic Acid.

You should decide between using glycolic acid as a cleanser or as a toner every day, because they both have lower concentrations that are meant for daily use, then add a glycolic acid mask weekly. This will give you the full benefits of the acid while being safe for your skin. You should note that glycolic acid is a powerful ingredient and should be introduced into skincare routines slowly, you can start up by using it every other day till your skin builds tolerance to the acid before considering of using it everyday.

Caution: Don’t forget to wear your sunscreen during the day to protect your skin from the sun as glycolic acid can increase your skin’s sensitivity to the sun which may lead to sunburn — if the skin isn’t sufficiently protected.

Note: limit glycolic acid use at night-time only, as using during the day increases your skin’s sensitivity to the sun which may risk sun burn. Also endeavor to use sunscreen during the day (after using lactic acid at night).

Side Effect Of Glycolic Acid.

The usage of glycolic acid may be accompanied with some side effects. If you’re new to glycolic acid, note that it’s important to monitor how your skin reacts. Experiencing sensitivity or redness may be an indication that you should reduce the concentration of glycolic acid (Note: 10% should be the maximum for at-home glycolic treatments). If you feel the need to use higher glycolic acid concentration, consult your board-certified dermatologist for proper guidance and direction.
Those with sensitive skin are not recommended to use glycolic acid; instead, go for a gentler alternative like lactic acid.
