About this sunscreen

Shiseido Synchro Skin Self-Refreshing Foundation SPF 30 is a makeup product with sun protection, combining the chemical filter ethylhexyl methoxycinnamate with titanium dioxide. It wears with a balanced finish, stays lightweight, keeps white cast low, and is designed to work well as a base since it is itself a foundation. Protection is rated weak, which is typical for a tinted foundation worn at thin coverage, and its score of 49.0 reflects that. Treat it as a cosmetic top-up rather than your primary sunscreen.

Is Shiseido Synchro Skin enough sun protection on its own?

Protection is rated weak, which is typical for a foundation worn at thin makeup-level coverage. It is generally best treated as a top-up over a dedicated sunscreen rather than your only SPF.

Does the Shiseido Syncro Skin Self-Refreshing Foundation Spf 30 work as a makeup base?

Yes. It is itself a foundation, so makeup-base performance is rated good, with a balanced, lightweight finish and low white cast.

Is it mineral or chemical?

It uses a mix, pairing the chemical filter ethylhexyl methoxycinnamate with titanium dioxide.
