Yes. Our Triple Lift Molecule Mask and Theorem Serum duo are besties. So it’s your decision but honestly your skin will look and just be so much better if you mask 2x a week and serum 2x a day. Both products feature our obsessively, perfectly balanced Triple Hyaluronic Acid complex & unique HA Growth Factor. The Mask deep infuses skin, both above and below the skin’s natural barrier with nutrients, to create an immediate lifting, smoothing, super well-rested effect. The Serum is clinically proven to help rebuild skin better over time (including improving firmness 200% for starters) and it gives you instant glow and hydration. Having said that, if you’re only up for trying one new thing just right now, you can mask or serum solo.
