Quartz

Quartz is a naturally occurring mineral, a form of silicon dioxide. In cosmetics, it is often used as an abrasive for exfoliation, a bulking agent, or to provide a soft-focus effect by diffusing light. Its physical properties make it useful for improving product texture and appearance.

BenefitMinimal 1 / 4

Texture i1 / 4

Whether it can improve smoothness and surface texture — roughness, flaking, clogged pores, or unevenness. Exfoliating acids, retinoids, and smoothing moisturizers may score here.

RiskLow 1 / 4

Irritation i1 / 4

Risk of short-term irritation — stinging, burning, dryness, redness, or discomfort. Common for strong actives, acids, retinoids, fragrances, and harsh surfactants.

Sensitization i0.5 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

Systemic exposure i0.1 / 4

Whether it has meaningful potential to be absorbed into the body at levels that may matter biologically. Most cosmetic ingredients score low unless there is known concern or high exposure.

Frequently asked questions

Is quartz safe for exfoliation?

When finely milled, quartz can be a safe and effective physical exfoliant. However, larger particles may cause micro-tears or irritation, especially on sensitive skin.
