Glycolic Acid Benefits: Resurface Your Skin With This AHA Powerhouse
What Is Glycolic Acid?
Glycolic acid is an alpha hydroxy acid (AHA) that comes from sugar cane. and of these acids, it has the. What makes it exceptional remarkably is it’s small molecular structure - the smallest among all AHAs. This unique characteristic allows it to penetrate deeply into the follicle, unlike most topical skincare ingredients.
Not only does glycolic acid reach the follicle, but it also functions as a delivery agent, enhancing the efficacy of other active ingredients in various formulations.
What does Glycolic Acid Do?
Glycolic acid works by dissolving and dislodging the glue-like substance between cells in the stratum corneum (your skin's outermost layer). This helps skin cells maintain a flat and organized structure, resulting in light reflection that creates a radiant appearance.
As we get older, these cells become disorganized and pile up, causing:
Dull-looking skin
Thicker, coarser texture
Enlarged pores and follicles
More visible fine lines and wrinkles
The stratum corneum also contains vital moisturizing substances between cells - mucopolysaccharides, ceramides, phospholipids, and hyaluronic acid. These compounds, known as glycosaminoglycans, provide the skin with volume, moisture, and barrier function. Unfortunately, their production diminishes with age.
Glycolic acid not only gently lifts cells apart without abrasion but completely reorganizes the epidermis. Its benefits are not just secluded to the epidermis but expand into the dermis, helping to thicken this crucial layer. This is important because while our stratum corneum thickens with age, our dermis thins. The dermis is composed of approximately 80% collagen, which we lose at a rate of 1-2% annually after age 20.
The extensive research behind glycolic acid almost rivals that of retinol, making it one of the most scientifically supported skincare ingredients available.
Can Glycolic Acid Help My Acne?
Yes! Glycolic acid helps break up that glue-like substance within the follicle where skin cells stick together - the very beginning of the acne formation process. So it can help disrupt the acne cycle.

Common Misconceptions About Glycolic Acid
Similar to retinol, a common myth suggests that glycolic acid thins the skin. This is a major misconception. While glycolic acid does thin the stratum corneum (which is beneficial), it simultaneously thickens the dermis - the deeper, structural layer of skin.
The ideal outcome is a compact, smooth stratum corneum that reflects light beautifully while supporting a thicker, healthier dermis underneath.
