Riversol Anti-Aging Reparative Serum vs Elm Biosciences A3O Elemental Serum

Buy the Riversol Anti-Aging Serum if you want a gentle, fragrance-free daily serum with a photostable vitamin C and beta-thujaplicin, and you have sensitive skin or prefer to layer under sunscreen in the morning. Buy the Elm Biosciences A3O Elemental Serum if you want an overnight retinoid treatment and are ready to build a night routine around it. The Riversol is lighter and easier to slot into an existing routine; the Elm is a cream with retinol plus bakuchiol, so it does more of the renewal work but is heavier and needs a slower start. Owners of the Riversol praise its tolerance on reactive skin; the Elm draws people who want retinoid results without the peeling.

• Choose the Riversol Anti-Aging Serum if you want a light, fragrance-free serum you can wear every morning under moisturizer and sunscreen, especially if your skin reacts to stronger actives.
• Choose the Elm Biosciences A3O Elemental Serum if you want a night cream built around a retinoid and are willing to start a few nights a week and build up.
