Is the Marshwillow Daily UV Protect Sunscreen Serum SPF 30 Pa+++ mineral or chemical?
It is a hybrid chemical sunscreen. The filters are octinoxate, Tinosorb M, octocrylene and benzophenone-4, with no mineral zinc or titanium.
Does the Marshwillow Daily UV Protect Sunscreen Serum SPF 30 Pa+++ leave a white cast?
White cast is generally low. The serum texture absorbs in and wears with a balanced, lightweight finish.
Is it good for acne-prone skin?
It has a low pore-clogging profile, which commonly suits blemish-prone skin. It may feel mildly stinging near the eyes for some, so keep it off the lash line.
