Sun protection has real evidence.
A randomized trial in 903 adults found less progression of measured skin aging with daily sunscreen than with discretionary use over 4.5 years. The reported relative odds were 0.76—not a promise of being “24% younger.”
Shade and protective clothing belong in the routine too. Dermatology guidance recommends broad-spectrum, water-resistant SPF 30 or higher on exposed skin.
Moisturizer can serve a medical purpose.
A Cochrane review of eczema trials found that moisturizers generally helped, though certainty varied by outcome. That supports a role in eczema care, not a requirement for every person to buy an elaborate routine.
If a product relieves dryness or is part of your treatment plan, keeping it is compatible with doing less.
Some medicines work. Marketing still needs scrutiny.
A review of seven randomized trials supported topical tretinoin for visible photoaging. Those findings do not transfer to every over-the-counter retinol, every strength, or every person.
A prescribed treatment is a different decision from an optional fragranced body product. Do not stop or taper medication because of this website; discuss changes with your clinician. The aim is a useful routine, not a competition to own nothing.
Let a product earn its place by solving a problem you actually have. You do not need to purchase youth, and you do not need to reject effective care to be a minimalist.
What we still don’t know
No trial promises permanent youth. Studies of a specific treatment and outcome cannot validate all claims made by the beauty or pharmaceutical industries.
