Cross-linked form of dimethicone, a polymer network of siloxane chains. Functions as a thickener, emulsion stabiliser, and texture modifier – providing the characteristic 'silky-powder' feel loved in primers and mattifying bases. Visually fills fine skin irregularities and wrinkles. Non-comedogenic. A common component in blurring effects in sunscreens and foundation bases.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Functional silicone polymer. No standalone active skin effect. CIR safety assessment is favourable. In complex formulations with other film-formers it can contribute to pilling.
Dimethicone Crosspolymer is a cross-linked polymer network of siloxane chains of dimethicone. Forms a 'silicone elastomer' – a soft rubber-like material with a silky-powdery texture. Mechanism. In a formula it works as a thickener, emulsion stabilizer, texture modifier. On skin it gives a characteristic 'velvety' feel, optically fills fine irregularities and wrinkles, creates a blurring effect. Doesn't form a long-lasting occlusive film. Where applied. Primers, foundations, mattifying makeup bases, sunscreens, 'soft focus' creams, eye products. In Spain – all mass-market color lines L'Oréal, Maybelline, Bourjois, MAC, Charlotte Tilbury, NARS foundations. Evidence base. A functional ingredient. Sensory and optical characteristics (blurring, silky-powdery texture) confirmed in standard tests. No active skin pharmacology – a functional component. Safety. CIR confirmed Dimethicone Crosspolymer safe in cosmetic use. Hypoallergenic, non-comedogenic (rating 0). Suitable for fungal acne patients (Malassezia doesn't grow on it). Unlike cyclic silicones D4/D5, the cross-polymer isn't environmentally persistent and has no regulatory restrictions. Pregnancy and lactation – safe. Systemic absorption through intact skin is low; no embryotoxicity identified. Best suited to: any skin and hair type. Especially interesting for patients with fungal acne, enlarged pores, textural irregularities. Almost a standard in color cosmetics.

The Evigrade extension adds an evidence panel to Wildberries, Goldapple, Letu, iHerb, Sephora and 12 more stores. This ingredient and every other one in the product show evidence-tier, allergen risk and pregnancy/lactation flags at a glance.
Dimethicone Crosspolymer is considered safe during pregnancy at typical cosmetic concentrations. Systemic absorption through the skin is minimal.
Dimethicone Crosspolymer suits: normal, dry, combination, oily. Use with caution in: sensitive.
Cross-linked form of dimethicone, a polymer network of siloxane chains.
On the Fulton scale 0/5 – non-comedogenic. For acne-prone skin, a rating of 3 or higher suggests choosing an alternative.
The INCI name is Dimethicone Crosspolymer. It may also appear as: Dimethicone/Vinyl Dimethicone Crosspolymer, Silicone Crosspolymer, Диметикон кросс-полимер.
