What is Glycolic Acid?
Glycolic acid is a type of alpha-hydroxy acid (AHA) that is derived from sugar cane. It is a water-soluble acid commonly used in skincare products to exfoliate the skin, improve skin texture and tone, and reduce the appearance of fine lines and wrinkles. Glycolic acid works by breaking down the bonds between dead skin cells, allowing them to be easily removed, revealing smoother, brighter skin. It is also used in chemical peels and can be found in varying concentrations in many over-the-counter and prescription skincare products.
How does Glycolic Acid Work?
Glycolic acid works by penetrating the outer layer of the skin and breaking down the bonds between dead skin cells, which are then sloughed off. This process of exfoliation helps to reveal smoother, brighter, and more even-toned skin. Additionally, glycolic acid can stimulate collagen production, which can improve the appearance of fine lines and wrinkles over time. It also has humectant properties, which means it can attract and retain moisture in the skin, helping to keep it hydrated and plump. Glycolic acid is considered an effective exfoliant and a valuable ingredient in many skincare products.
What are the benefits of Glycolic Acid?

- Skin irritation: Glycolic acid can cause redness, dryness, itching, and flaking, especially in individuals with sensitive skin.
- Sun sensitivity: Glycolic acid can make the skin more sensitive to the sun, which can increase the risk of sunburn and other forms of sun damage.
- Hyperpigmentation: In some cases, glycolic acid can cause dark spots or patches on the skin, especially if it is used in high concentrations or for long periods.
- Chemical burns: If glycolic acid is not used properly, it can cause chemical burns, which can be painful and may require medical attention.
