Glycolic acid has the smallest sized molecules of all the alpha-hydroxy acids. Because of these super tiny molecules, glycolic acid can easily penetrate the skin. This allows glycolic acid to exfoliates the skin more effectively than other AHAs.
Glycolic acid works by speeding up cell turnover. It helps dissolve the bonds that hold skin cells together, allowing dead skin cells to slough off more rapidly than they would on their own.
Glycolic acid also stimulates your skin to create more collagen. Collagen is the protein that gives skin its firmness, plumpness, and elasticity. (Collagen is also the protein that gives strength to your bones and connective tissues.) As you age, collagen production naturally slows down. It's also destroyed by excessive sun exposure. Using glycolic acid regularly can help prevent this breakdown of collagen.
Glycolic acid is an incredibly popular treatment because of the many benefits it has for the skin. It has effective skin-renewing properties, so it is often used in anti-aging products. It can help smooth fine wrinkles and improve the skin's tone and texture. Glycolic acid plumps the skin and helps boost hydration levels.
It's not just an anti-aging treatment, though. Glycolic acid can also help fight sun damage. It's often used to fade minor fade hyperpigmentation too.
Because it's an effective exfoliator, using glycolic acid regularly can help brighten the complexion. It's this exfoliating property that also makes it an effective preventative against ingrown hairs. If you have large pores, glycolic acid can help make those appear smaller as well.
Many acne treatment products also contain glycolic acid. Glycolic acid can help keep pores clear from blockages, preventing comedones, blackheads, and inflamed breakouts from forming
People may refer to their skin tone as uneven if they have patches or blotches of hyperpigmentation (darker or lighter patches) or redness across their face. This might include red streaks across the forehead, the tip of the nose and cheeks. It could also refer to age spots or sunspots, acne scars, or patches of dull and lifeless looking skin from aging or UV damage. Overly dry skin can cause damage to the follicles and production of collagen and sebum, which can cause the skin to appear duller or ashy.
To brighten the skin and provide a more even skin tone, it’s best to moisturize daily and wear sunscreen. Additionally, antioxidants protect the skin from free radicals that damage cells and speed up aging, which can cause dark spots and make acne scarring worse. Ingredients and nutrients like vitamin C, rumex, arbutin, rosehip oil, jojoba oil, retinol/vitamin A, coenzyme Q10, alpha-hydroxy acid and salicylic acid are all beneficial for evening out the complexion.
Since sun damage is the leading cause for uneven skin tone, it is important to wear sunscreen daily in combination with brightening ingredients.
glycolic acid may be effective for uneven skin tone, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you.
