Glycolic Acid powder is a high-purity crystalline form of glycolic acid, typically used as a raw material to create custom skincare formulations like peels, serums, and toners. It is a potent alpha-hydroxy acid (AHA) derived from sugarcane known for its small molecular size, which allows it to penetrate skin more deeply than other AHAs to exfoliate dead cells and stimulate collagen.
Key Skincare Benefits
Glycolic acid is widely regarded as a "holy grail" for exfoliation due to its ability to dissolve the "glue" holding dead skin cells together.
-
Anti-Ageing: It stimulates cell renewal and collagen production, helping to reduce the appearance of fine lines, wrinkles, and loss of elasticity.
-
Acne & Blemish Control: By unclogging pores of sebum and dead cells, it helps prevent breakouts and can fade post-acne scarring.
-
Hydration: As a humectant, it attracts moisture to the skin's surface, making it effective for treating dry or patchy skin.
-
Hyperpigmentation: Regular use helps even out skin tone by removing surface discolouration from sun damage or melasma.
Usage and Safety Precautions
Because pure powder is extremely acidic (pH levels can be as low as 0.5), it must never be applied directly to the skin.
-
Dilution is Mandatory: Powder must be dissolved in distilled water and formulated to a safe concentration, typically between 5% and 10% for at-home use.
-
pH Balancing: Formulations often require a pH adjuster (like baking soda or sodium hydroxide) to raise the pH to a safe but effective level, usually between 3.0 and 4.0.
-
Sun Sensitivity: Glycolic acid significantly increases UV sensitivity. It is essential to wear broad-spectrum SPF 30+ daily during and after treatment.
-
Patch Testing: Always perform a patch test on a small area 24 hours before full application to check for adverse reactions.
-
Ingredient Conflicts: Avoid using it in the same routine as other potent actives like retinol, Vitamin C, or other strong exfoliants (like salicylic acid) to prevent severe irritation
Warning: Handling pure glycolic acid powder requires protective gear, including eye protection, as it is a corrosive irritant. If you are not experienced in chemical formulation, consider using pre-made glycolic acid products instead
