Diamond Powder

Diamond powder is a finely milled form of diamond, one of the hardest naturally occurring materials. In skincare, it functions as a physical exfoliant, designed to remove dead skin cells and surface debris through mechanical abrasion rather than chemical dissolution.As an abrasive ingredient, diamond powder works purely through physical means—its hard particles are intended to slough away the outermost layer of skin when massaged across the surface. It appears in a small proportion of skincare formulations, typically in cleansers or scrubs aimed at manual exfoliation.

Diamond powder exfoliates through mechanical action. The hard particles create friction against the skin's surface, physically dislodging dead cells and surface impurities when the product is massaged across the face or body. This differs from chemical exfoliants, which dissolve and break down cellular bonds using acids or enzymes.Because diamond is exceptionally hard, particles remain relatively intact during use, allowing for controlled, uniform abrasion. The degree of exfoliation depends on particle size, concentration, and how vigorously the product is applied.

Use diamond powder products gently and avoid over-exfoliation, which can compromise the skin barrier and cause irritation. Physical exfoliants are typically used 1–3 times per week depending on skin sensitivity and tolerance. Always dampen the skin with water before application, use light pressure, and follow with a hydrating moisturiser and broad-spectrum sunscreen during the day. Avoid use if the skin is broken, inflamed, or severely compromised.

Diamond powder is generally regarded as safe for topical use in cosmetics. However, as with all physical exfoliants, there is potential for micro-abrasion if used too frequently or with excessive pressure, particularly on sensitive or reactive skin.
