Lia is the research editor behind Your Skin Tells Everything. Our reviews are research-based analyses — we evaluate published ingredient and clinical studies, brand formulation data, regulatory sources, and aggregated verified user feedback rather than one-off personal trials. We call out weaknesses as well as strengths, and note when the evidence is thin. This is editorial information, not medical advice — for skin conditions, please consult a licensed professional. Some links are affiliate links; if you buy through them we may earn a small commission at no extra cost to you, and it never changes our verdict.
