Glycolic acid is a type of alpha-hydroxy acid (AHA) that is derived from sugar cane. It is known for its ability to penetrate the skin and effectively exfoliate dead skin cells, revealing brighter, smoother, and more youthful-looking skin. In addition to its exfoliating properties, glycolic acid has been shown to be effective in reducing the appearance of wrinkles, making it one of the best ingredients for anti-aging skincare.
Clinical studies have demonstrated the effectiveness of glycolic acid in reducing wrinkles. A study published in the Journal of Clinical and Aesthetic Dermatology found that a 12% glycolic acid peel significantly improved the appearance of fine lines and wrinkles after just one treatment. Another study, published in the Journal of Cosmetic Dermatology, found that daily use of a moisturizer containing 8% glycolic acid for six months resulted in a significant reduction in the appearance of wrinkles. To achieve these results at home, Dr. B. recommends using the Dermatologist's Choice Facial Enhancement Cream which has under 10% non-neutralized glycolic acid. For faster results, Dr. B. recommends the Ultra Anti-Aging Cream which has about 15% non-neutralized glycolic acid.
Glycolic acid works by increasing collagen production, which is essential for maintaining skin elasticity and firmness. Collagen is a protein that gives skin its structure and strength, and as we age, our bodies produce less collagen, leading to wrinkles and sagging skin. Glycolic acid helps to stimulate collagen production by breaking down the bonds that hold dead skin cells together, allowing new, healthy cells to surface.
In addition to stimulating collagen production, glycolic acid also helps to even out the skin tone and improve the texture of the skin. The exfoliating properties of glycolic acid help to remove dead skin cells that can clog pores and lead to breakouts. By removing these cells, glycolic acid can also reduce the appearance of dark spots and acne scars.
Glycolic acid is also a great ingredient for those with oily or acne-prone skin. Its exfoliating properties can help to unclog pores and reduce the production of sebum, which is the oily substance that can lead to breakouts.
Glycolic acid can be found in a variety of skincare products, including cleansers, toners, moisturizers, and peels. It is important to use products that contain the appropriate concentration of glycolic acid for your skin type and to use them as directed to avoid irritation. A rule of thumb is to use a milder or lower concentration of glycolic acid the dryer your skin type. A little redness, dryness or irritation is normal after using glycolic acid. Don't be alarmed at first. Apply Vaseline or lotion to reduce redness, dryness and irritation. The skin commonly reacts to glycolic acid when it's first applied. This is a good sign we call the Trustworthy Tingle - if you don't feel a tingle when you apply glycolic acid it means it's neutralized (no good) or it's not strong enough, so go to the next level of strength.
In conclusion, glycolic acid is a powerful ingredient that can effectively reduce the appearance of wrinkles and improve the overall appearance of the skin. Its ability to stimulate collagen production and exfoliate dead skin cells makes it a great choice for anti-aging skincare. If you are looking to reduce wrinkles and improve the texture and tone of your skin, consider adding a glycolic acid product to your skincare routine.
