How to Use Glycolic Acid
Glycolic acid has become a buzzword in the skincare industry, celebrated for its exfoliating prowess and skin-brightening benefits. But with such a powerful ingredient, knowing how to use it correctly is essential. This guide will walk you through everything you need to know about glycolic acid, including what it is, how to use it, its benefits, and whether it’s right for your skin type and concerns.
What Is Glycolic Acid?
Glycolic acid is a type of alpha-hydroxy acid (AHA) derived from sugarcane. It’s the smallest AHA molecule, which allows it to penetrate the skin deeply and effectively. This penetration enables glycolic acid to exfoliate dead skin cells, improve skin texture, and reveal a brighter, more radiant complexion.
Key Benefits of Glycolic Acid:
-
Exfoliation: Removes dead skin cells, reducing dullness.
-
Brightening: Helps even out skin tone and fade dark spots.
-
Anti-Aging: Boosts collagen production, minimizing fine lines and wrinkles.
-
Acne Prevention: Unclogs pores, reducing the likelihood of breakouts.
What Is the Difference Between Glycolic Acid and AHA?
While glycolic acid is a type of alpha-hydroxy acid (AHA), not all AHAs are glycolic acid. Here are the key differences:
Glycolic Acid:
-
Derived from sugarcane.
-
Smallest AHA molecule, allowing deeper skin penetration.
-
Highly effective for exfoliation and collagen stimulation.
AHAs (General):
-
Include other acids such as lactic acid, citric acid, and mandelic acid.
-
Each AHA varies in molecular size and function; for example, lactic acid is gentler and more hydrating, while mandelic acid is ideal for sensitive skin.
-
AHAs as a group focus on exfoliating the skin's surface and improving texture and tone.
In essence, glycolic acid is a potent AHA known for its efficiency and deep action, making it a top choice for those seeking intensive exfoliation.

When introducing glycolic acid into your skincare routine, it’s important to start slow and build up your skin’s tolerance.
Step-by-Step Guide:
