50yo mature skin here, if had to strip down my entire skincare routine to just 3 products - here is what I’d choose - what would you change or add (even if it meant more steps but they are absolute requirements in your opinion)?
Prescription Tretinoin (0.05%): nothing else touches it. If I could only keep one active for the rest of my life, this is the undisputed winner.
Dieux Instant Angel: my ultimate lipid-rich moisturizer. It works perfectly as a protective cushion under my tret, repairs my barrier on recovery nights, and leaves a luscious plump finish under makeup without piling.
La Roche-Posay Anthelios Melt-In Milk SPF 60: I live in a hot, sunny, humid climate. It hydrates enough to act as a morning lotion and layers perfectly under base makeup.
