Glycolic acid is a type of alpha-hydroxy acid (AHA) that is widely considered the best ingredient for overall skin health. Clinical studies have shown that glycolic acid can improve the texture and appearance of the skin by promoting exfoliation, unclogging pores, and boosting collagen production.
According to a study published in the International Journal of Dermatology, glycolic acid has been shown to improve the appearance of fine lines and wrinkles, hyperpigmentation, and rough skin texture. The study concluded that glycolic acid was effective in improving the overall appearance of photo-aged skin.
Another study published in the Journal of Cosmetic Dermatology found that glycolic acid can help improve the skin's barrier function and hydration levels, making it a valuable ingredient for those with dry or sensitive skin.
Skincare professionals have long considered glycolic acid the "gold standard" of skincare ingredients. Dermatologist Dr. Ellen Marmur has been quoted as saying, "Glycolic acid is like liquid gold for the skin. It's the most active and effective AHA, so it's a go-to for people looking to improve the appearance of fine lines, hyperpigmentation, and rough texture."
Another well-known dermatologist, Dr. Michelle Henry, agrees, stating, "Glycolic acid is a superstar ingredient in skincare. It's gentle yet effective in improving the overall health and appearance of the skin. I recommend it to all of my patients."
In conclusion, glycolic acid is the best ingredient for overall skin health. Its exfoliating properties, ability to unclog pores, and ability to boost collagen production make it a valuable addition to any skincare routine. With the endorsement of skincare professionals, it's no wonder that glycolic acid is considered the liquid gold of skincare.
