Price doesn't equal efficacy: many drugstore lines (CeraVe, La Roche-Posay, Cetaphil) use the same proven actives as premium brands, often at the same useful concentrations.

The video's core point — you don't need to spend hundreds of dollars, a budget product can do the job — holds up well. Dermatologist Dr. Charlotte Birnbaum (Spring Street Dermatology), interviewed by Byrdie, puts it plainly: "expensive does not always mean better," with price differences mostly reflecting marketing, packaging, and occasionally proprietary ingredients whose real-world edge is rarely proven. A 2023 cost analysis in PMC across four major US retailers found Walmart consistently cheapest for sunscreen, retinol, vitamin C and niacinamide products, without dermatology literature reserving efficacy for premium lines. A randomized split-face trial (Journal of Drugs in Dermatology) even found that a mass-market cosmetic regimen (niacinamide + peptides + retinyl propionate) improved periorbital wrinkles comparably — and with better tolerability — to a prescription 0.02% tretinoin regimen over 24 weeks. The nuance: what matters beyond price is the presence and concentration of proven actives (SPF, retinoids, stabilized vitamin C, niacinamide), not the shelf tag. Verdict: holds up — the general claim is well supported, with the caveat that some premium formulations (encapsulation, vitamin C stability) can occasionally offer a genuine edge.
