Dermatologist backs budget retinol as Prime Day deal highlights an $18 serum

A viral TikTok post by Dr. Neera Nathan, a Harvard-trained dermatologist and skin cancer surgeon, claims that an $18 retinol serum can deliver "immediate results." The video, which has more than 550,000 views, has sparked renewed interest in affordable skincare and questions the notion that only expensive products deliver real benefits. Nathan highlighted a budget-friendly retinol serum currently selling for about $18 before Prime Day, noting that shoppers can see noticeable improvements without paying a premium.

Retinoids are derivatives of Vitamin A and are commonly used to treat acne, wrinkles, and signs of aging. They work by increasing skin cell turnover and promoting collagen production, which can help smooth rough patches, minimize the appearance of pores, plump fine lines, and brighten the complexion.

Among the highlighted options is CeraVe Skin Renewing Retinol Serum for the face. It is discounted by 25% in an early Prime Day deal ahead of Oct. 7-8. The formula includes ceramides and niacinamide, and pairs retinol with hyaluronic acid. CeraVe's patented MVE Technology releases ingredients gradually to extend hydration and reinforce the skin's protective barrier after application. One reviewer cited its fragrance-free, non-comedogenic design and noted it helps control breakouts and smooth fine lines.

The product has racked up more than 30,000 purchases in the past month, according to shopper data cited by retailers, underscoring the demand for budget-friendly yet dermatologist-backed options. Health and beauty retailers have leaned into retinol as a staple for daytime routines when used with sunscreen, and brands have emphasized barrier-support ingredients like ceramides and niacinamide to soothe sensitive skin.

While retinoids can offer noticeable benefits, dermatologists caution that users should start slowly, patch test new products, and use sunscreen daily. They also advise avoiding retinoids during pregnancy or on irritated skin and consulting a dermatologist if irritation or persistent redness develops. Consumers are urged to verify current sale terms, as Prime Day discounts can change or expire.

The surge of interest in affordable retinoids reflects a broader trend toward value-driven skincare, where consumers seek clinically backed benefits without paying premium prices. As Prime Day approaches, shoppers may see more budget-friendly options promoted alongside familiar, dermatologist-approved brands, with experts reiterating that the core science—retinoids boosting cell turnover and collagen—remains central to many anti-aging routines.
