Product: DL-Mandelic Acid
Rchem DL-Mandelic Acid is a high-purity, alpha-hydroxy acid (AHA) derived from bitter almonds, presented as a white to off-white crystalline powder. This unique AHA features a large molecular size and a lipophilic benzene ring, which allows for gentle, slow penetration into the skin. Renowned for its effective exfoliating, antibacterial, and brightening properties, it is a cornerstone ingredient for treating acne, hyperpigmentation, and photoaging, and is particularly suitable for sensitive and rosacea-prone skin types that may not tolerate other AHAs.

Frequently Asked Questions:
What makes Mandelic Acid gentler than Glycolic Acid?
The key difference is molecular size. Glycolic acid has the smallest molecule of all AHAs, allowing for very fast and deep penetration, which can cause significant irritation. Mandelic Acid's large molecule penetrates the skin slowly and gradually, providing a milder, more controlled exfoliation that is less likely to cause side effects.
Yes, it is an excellent choice for melasma. Its gentle exfoliating and brightening actions are effective for managing this condition, which is often worsened by irritation (a phenomenon known as post-inflammatory hyperpigmentation). Its low irritation profile makes it a safer option for long-term use on melasma-prone skin.
Is DL-Mandelic Acid suitable for treating melasma?
Yes. While it was first isolated from bitter almonds, the commercial ingredient used in cosmetics is produced synthetically and does not contain any almond-derived proteins that trigger allergic reactions. It is considered safe for use by individuals with nut allergies.
Can Mandelic Acid be used by individuals with a nut allergy?
The "DL" prefix refers to the racemic mixture of the two enantiomers (D-form and L-form) of the molecule. The naturally occurring form is primarily L-Mandelic Acid, but the synthetic DL mixture is most commonly used in cosmetics and is equally effective. This distinguishes it from the single-isomer versions.
Why is it called "DL-Mandelic Acid"?
Store in a cool, dry place in a tightly sealed container. It is a solid acid, so it must be dissolved in the water phase of a formulation. When creating leave-on products, the final pH should be adjusted to between 3.5 and 4.2 for optimal efficacy and tolerance. Standard personal protective equipment (PPE) like gloves and a dust mask is recommended when handling the powder. Always refer to the Safety Data Sheet (SDS) for comprehensive handling information.
