Mandelic Acid 99% 100 g

Why Mandelic Acid Has Become a Go-To Ingredient for Gentle Chemical Exfoliation

Mandelic acid 99% is an alpha-hydroxy acid distinguished by a larger molecular size compared to glycolic or lactic acid, which allows it to penetrate the skin more slowly and gently. This characteristic has made it one of the most sought-after ingredients in the formulation of chemical peels, anti-aging serums, post-acne and pigmentation treatments, and products designed for sensitive, redness-prone skin. The ingredient belongs to the category Acids, Salts, Alcohols, and Alkalis, where raw material acids for functional cosmetics and laboratory formulations are gathered, and the 100 gram package is well suited both for home experimentation and small studio production batches.

The primary global demand for mandelic acid comes from professional and at-home skincare: surface peels for face and body, brightening serums, products targeting acne-prone and oily skin, and gentle exfoliants for delicate areas around the eyes and neckline. The acid carries mild antibacterial properties, which explains its popularity in blemish control formulas and men's aftershave products. Beyond cosmetics, the compound is also used as a laboratory reagent and in certain industrial synthesis processes, though skincare formulation remains the dominant driver of worldwide interest in this ingredient.

In formulations, mandelic acid is typically introduced into the water or water-alcohol phase at a temperature not exceeding 40 degrees Celsius to preserve molecular stability. Working concentrations range from 5 to 30 percent for peel treatments and from 2 to 10 percent for daily-use serums and toners. Maintaining the finished product within a pH range of roughly 3.5 to 4.5 is important for predictable and comfortable skin performance. The acid pairs well with other active ingredients; it is frequently combined with Nicotinic Acid to enhance tone-evening effects, and with Glutamic Acid to add moisturizing support and reduce irritation. In complex anti-aging blends it is also paired with Phytic Acid for a gentler approach to pigmentation and skin firmness.

The dry powder should be stored in an airtight container, in a cool, dry place away from direct sunlight, avoiding contact with metal containers during solution preparation — glass or plastic vessels are preferred. Finished products containing mandelic acid should be kept in opaque packaging, since prolonged exposure to light and heat can reduce the acid's activity over time. When handling the concentrated powder, gloves should be worn and contact with mucous membranes avoided.

For those preparing their first trial cosmetic batches at home, the 100 gram package allows testing several formulations without significant raw material costs, while small studios can rely on it for a steady supply lasting several months of regular production.
