Which Anti-Aging Skincare Ingredients Actually Work?
Which anti-aging skincare ingredients actually work — and what can each one reasonably claim?
This episode compares retinoids, hyaluronic acid, peptide serums, and collagen creams by starting with the outcome each product promises. It explores the evidence for topical retinoids and visible signs of photoaging, including wrinkles, texture, and pigmentation, along with the differences between over-the-counter retinol and retinal and prescription tretinoin.
It also looks at hyaluronic acid for hydration and smoother-looking skin, why peptide evidence can depend on the exact ingredient and formulation, and why topical collagen claims require careful interpretation.
The useful question is not simply which ingredient sounds impressive. It is whether that ingredient matches the result you actually want.
