Glycolic Acid

Glycolic acid is an alpha hydroxy acid (AHA) derived from sugarcane and is known for its small molecular size, which allows it to penetrate the skin effectively. It works by loosening the bonds between dead skin cells, helping them shed from the surface. This improves skin texture, clarity, and radiance while supporting natural cell turnover.

In skincare, glycolic acid is commonly used in cleansers, toners, serums, and peels to exfoliate and renew the skin. Regular, controlled use helps smooth rough texture, fade dark spots, and improve uneven skin tone. Because it increases skin sensitivity to sunlight, glycolic acid should be used carefully and paired with sunscreen. It is best introduced gradually, especially for sensitive skin.

FAQs

What is glycolic acid?

Glycolic acid is an alpha hydroxy acid derived from sugarcane. It has a small molecular size, which allows it to penetrate the skin easily. Glycolic acid works by removing dead skin cells from the surface. This helps improve skin texture and brightness.

How to use glycolic acid?

Glycolic acid is usually applied after cleansing and before moisturising. Beginners should start with lower concentrations and use it a few times a week. It is best used at night to reduce sun sensitivity. Daily sunscreen use is essential when using glycolic acid.

Does glycolic acid remove tan?

Glycolic acid helps fade tan by exfoliating pigmented dead skin cells. It does not stop melanin production but speeds up skin renewal. With regular use, skin tone appears more even. Results depend on sun exposure and consistency.

What does glycolic acid do for skin?

Glycolic acid exfoliates the skin and promotes faster cell turnover. It helps smooth rough texture and improve dullness. It also supports the reduction of dark spots over time. Skin appears clearer and more refined with consistent use.

Can we use glycolic acid everyday?

Daily use depends on the product strength and skin tolerance. Mild formulations may be used more frequently. Stronger concentrations should be used less often. Overuse can cause irritation or sensitivity.

Does glycolic acid lighten skin?

Glycolic acid does not bleach or change natural skin colour. It helps brighten skin by removing surface pigmentation. This results in a more even skin tone. Any lightening effect is gradual and surface-level.

Can glycolic acid be used daily?

Yes, but only in low concentrations and if the skin tolerates it well. Many people prefer using it two to three times a week. Daily use without sunscreen can lead to sensitivity. Monitoring skin response is important.

Does glycolic acid remove dark spots?

Glycolic acid helps fade dark spots by increasing skin cell turnover. It removes pigmented cells from the skin surface. Results take time and consistent use. Sun protection improves outcomes.

Can I use niacinamide with glycolic acid?

Yes, niacinamide can be used with glycolic acid. Glycolic acid exfoliates, while niacinamide helps calm the skin. They can be used together or at different times. This combination supports balance and tolerance.

Can I use salicylic acid and glycolic acid together?

Salicylic Acid and Glycolic Acid can be used together with caution. Both are exfoliating acids and may increase irritation. Many routines alternate them on different days. This reduces the risk of over-exfoliation.
