Vitamin C serums!
For why: used in the morning to boost sun protection.
May have same effect used at night (and indeed morning and night). Reports back from Elfy (see comment), also other MUAers known to apply twice daily for sun-protection-boosting purposes.
Some people also use at night, for (allegedly) collagen production, often as an anti-ageing thingie. Each to their own as ever, but basically I disapprove: building collagen in skin that’s medically damaged is one thing, but otherwise—folly be praised!!!—vacuous vanity.
On the other hand: it’s your serum and your skin. No-one’s going to come round, invade the privacy of the inner sanctum that is your bathroom, and
interrogate check with you whether you’re applying it at night for sun protection, for anti-aging, both, a bit of each, or somewhere in between.
