Applying it at night is not wrong, but it means the antioxidant is largely gone by the time the damage occurs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eVitamin C and sunscreen are genuinely complementary:\u003c\/strong\u003e sunscreen blocks most UV, and the antioxidant handles the fraction that gets through. Neither substitutes for the other, and together they do more than either alone. In Kuwait's UV levels that combination is the single most effective daytime pairing available.\u003c\/p\u003e\n\n\u003ch3\u003eThe instability problem — and what you should actually do\u003c\/h3\u003e\n\n\u003cp\u003eVitamin C is among the least stable ingredients in skincare.
