Dimethicone 350

Dimethicone 350 (Emollient) — higher-viscosity silicone emollient. Gives a smooth glide, mild theoretical comedogenicity. Safe for skin.

Dimethicone 350 is classified as use with caution — it can be a valuable ingredient, but is more likely to cause irritation or sensitivity for some skin types than a plain "safe" ingredient, so patch testing is worth doing first.

Dimethicone 350 has a comedogenic rating of 1 out of 5 — low, so it's unlikely to clog pores for most people, though very reactive skin can still respond individually.

Dimethicone 350 is classified as an emollient in the Pure Moonlight ingredient database. That classification reflects its primary functional role in a skincare formula.
