This is a YouTube video titled "Use Retinol At Night" (created 2024-05-10T12:01:00Z) featuring a single speaker (Speaker A), likely a skincare professional or content creator, giving practical guidance on retinoids—specifically tretinoin/tretinol. The speaker explains different forms, advises starting use 3–5 times per week and increasing as tolerated, warns about peeling and increased sun sensitivity (recommend applying at night and skipping use during high sun exposure like boating), and describes benefits (normalizes skin turnover, improves firmness, fine lines, wrinkles, and discoloration). The speaker also notes vitamin C can be used alongside tretinoin to brighten skin.
