Is the Universal Smoothing Base safe for sensitive, acne‑prone, or dry skin?

It is generally suitable for normal to oily skin because silica helps control shine, but the high proportion of silica and the mineral pigment CI 77491 can be drying or exacerbate irritation on very sensitive or acne‑prone skin; those with dry or reactive skin may prefer a more hydrating primer.

What role does silica play in this formula and how does it benefit the skin?

Silica is an absorbent mineral that reduces surface oil and creates a matte finish, while its fine particles scatter light to blur imperfections, giving a smoother appearance without adding weight.

How often should the primer be applied and does it contain any controversial ingredients?

The primer is intended for daily use under makeup, applied once per day to a clean face; it does not contain fragrance or parabens, but it includes CI 77491 (iron oxide pigment) and a high level of silica, which some consumers consider less gentle than fully natural alternatives.
