Mandelic Acid

Mandelic acid is a large-molecule alpha-hydroxy acid (AHA) derived from bitter almonds. Its size is what sets it apart - it penetrates the skin more slowly than glycolic or lactic acid, which makes it the most gentle AHA available and the most suitable for sensitive skin types, first-time acid users, and darker skin tones prone to post-inflammatory hyperpigmentation. While other AHAs resurface aggressively, mandelic acid exfoliates gradually and consistently. It dissolves the bonds between dead skin cells to reveal smoother, brighter skin, fades dark marks and pigmentation, improves skin texture, and has mild antibacterial properties that make it effective for acne-prone skin - a benefit most AHAs cannot claim. For South African skin tones, which are disproportionately affected by hyperpigmentation from stronger actives, mandelic acid provides an effective exfoliation pathway that avoids the rebound darkening risk associated with more aggressive peels. Use it two to three times per week in the evening and always follow with SPF50 the next morning. Mandelic Acid FAQs Is mandelic acid suitable for dark skin tones? Yes - it is one of the best exfoliating acids for darker skin tones. Its slow penetration rate significantly reduces the risk of post-inflammatory hyperpigmentation that stronger acids like glycolic can trigger in melanin-rich skin. Mandelic acid exfoliates effectively without overstimulating melanocytes, making it a reliable long-term exfoliant for all South African skin tones. How does mandelic acid compare to glycolic acid? Glycolic acid is a smaller molecule that penetrates faster and more deeply, producing quicker results but with higher irritation potential. Mandelic acid is gentler and slower - ideal for sensitive or reactive skin, darker skin tones, and those new to acid exfoliation. If glycolic has caused redness or irritation in the past, mandelic is typically well tolerated as an alternative. Can I use mandelic acid every night? Start with two to three times per week and progress to every other night as your skin adjusts over four to six weeks. Because of its gentle nature, many people do tolerate nightly use with time. Always apply SPF the following morning - all AHAs increase photosensitivity, and unprotected sun exposure will reverse the brightening results mandelic acid works to achieve. Can mandelic acid help with acne? Yes. Unlike most AHAs, mandelic acid has mild antibacterial properties that work against the bacteria involved in acne formation. It also exfoliates inside the pore, reducing congestion and breakout frequency. For sensitive, acne-prone skin that cannot tolerate salicylic acid or stronger BHAs, mandelic acid is an effective gentler alternative. What should I use with mandelic acid? Mandelic acid works well alongside niacinamide, hyaluronic acid, ceramides, and squalane. Avoid using it on the same night as retinol or other exfoliating acids to prevent over-exfoliation. In the morning after using mandelic acid at night, apply SPF50 without fail. Pairing it with a barrier-supporting moisturiser reduces any dryness during the adjustment period.
