The Science of Mandelic Acid

Exfoliates the skin's surface by promoting the shedding of dead skin cells, helping improve texture and radiance

Features a larger molecular structure than glycolic acid, allowing slower penetration and often improved tolerability

Helps reduce the appearance of post-acne marks, discoloration, and uneven skin tone

Supports clearer-looking skin by helping to prevent pore congestion and excess buildup

Encourages smoother, firmer-looking skin by promoting natural skin renewal processes

Mandelic Acid has a larger molecular size than many other AHAs, such as glycolic acid. This allows it to penetrate the skin more slowly, making it generally gentler and better tolerated by sensitive skin types.

Mandelic Acid is commonly used to improve uneven skin tone, dullness, rough texture, visible signs of aging, blemishes, and the appearance of post-acne discoloration.

Mandelic Acid is often considered one of the gentler AHAs due to its slower penetration rate. While many sensitive skin types tolerate it well, patch testing is recommended before regular use.

Yes. Mandelic Acid is commonly combined with ingredients such as niacinamide, hyaluronic acid, peptides, antioxidants, and soothing botanical extracts. Care should be taken when combining multiple exfoliating acids or potent actives to avoid over-exfoliation.

Many Mandelic Acid products are designed for regular use due to the ingredient's gentle nature. Usage frequency depends on concentration, formulation, and individual skin tolerance. Following product directions is recommended.
