Evidence-backed articles
Long-form skincare writing from Drop. Every claim links to peer-reviewed research, every recommendation tells you where the evidence is strong and where it isn't.
We cite our sources. We will not pressure you to add anything to your routine. The most useful answer is often “keep what you have” — and we'll say so.
