Glycolic acid exfoliates; NAD+ face cream is not an acid peel
Glycolic acid is an alpha-hydroxy acid used in cosmetic and dermatology routines to loosen dead surface cells and support smoother-looking texture. NAD+ face cream is a topical product category built around nicotinamide adenine dinucleotide biology and cosmetic skin-support positioning. They can appear together in anti-aging searches, but they are not substitutes and should not be compared as if one simply “works stronger.” A fair review starts with product strength, pH when available, skin type, current medications, recent procedures, and whether the claim is cosmetic or medical.
- Glycolic-acid strength, pH, leave-on versus rinse-off format, and frequency change irritation risk; high-strength peel advice should not come from a generic online routine.
- Topical NAD+ evidence should be framed conservatively and should not be presented as a proven acne, melasma, scar, wound-healing, hair-growth, or age-reversal drug.
- If the concern is rosacea, eczema, infection, melasma, severe acne, suspicious lesions, or persistent pigment change, diagnosis matters more than choosing another active.
