The claim
Fewer products means healthier skin and less irritation.
What the evidence says
Dermatology guidance has long favored simple routines built around sunscreen, a moisturizer, and a retinoid, and a 2025 Delphi consensus of cosmetic dermatologists converges on the same short list of ingredients. Fewer products reduce irritant and allergen exposure. The limit is that a diagnosed condition may still need prescription treatment.
Who should skip it
Nobody; people with acne, rosacea, melasma, or eczema should include the prescribed treatment in their short list.
What to do instead, or as well
Cleanser, moisturizer, sunscreen, plus a retinoid at night; add one targeted active only for a specific concern.
