Description

Your skin isn't just dry. It's depleted.

Skin loses more than moisture as hormones change. The barrier weakens, hydration escapes faster, and dryness, dullness and crepey texture get harder to ignore. Theorem Serum Boost works on that every morning and every night, replenishing the hyaluronic acid your skin makes less of on its own.

But some days need more than maintenance. That is what the Triple Lift Molecule Mask is for. Triple-weight hyaluronic acid, proprietary bio-fermented peptides and natural sugars to tighten and smooth, with visible effects in 15 minutes.

One product for the routine. One for the reset. That is how Skincare for Grownups® is meant to work.

What's included in the Duo:

Theorem Serum Boost, 30ml / 1 fl. oz.
Hyaluronic Molecular Nutrition and Bio-Intensified Peptide. The treatment step that supports hydration and firmness where mature skin needs it most.

Triple Lift Molecule Mask, 40 ml / 1.35 fl. oz.An award-winning firming mask designed for skin navigating hormonal shifts. This proprietary gel formula delivers visible lift, deep hydration, and long-term resilience — without microplastics or fillers.

I'm 51 and I have had good skin my whole life until perimenopause, when I began getting stubborn acne. Within 2–3 days of using the serum, I noticed my acne beginning to clear up.

— Susan M.

My hygienist had to double-check my date of birth. She couldn't believe I was 60.

— Becky K.

Better than Shiseido and Lancôme serums. I've been using facial serums for 14 years, and Caire's was immediately absorbed by my skin.

— Mayumi Y.

Frequently Asked Questions

Who is the Lift Duo for?

Skin 40 and over that needs daily support and an occasional reset. If your skin looks flat by Thursday, or you have an event and want it looking its best, this pairs the everyday serum with a 15-minute treatment.

How often should I use the mask?

The mask is a treatment, not a daily step. Use it when skin looks tired or before an occasion, and keep Theorem in your routine every morning and night.

How soon will I notice a difference?

The mask works in 15 minutes. The longer changes build with consistency: in clinical testing, 100% of women noticed softer, firmer skin after four weeks of twice daily use.*

Do I still need a moisturizer?

Yes. This duo covers treat and reset. Apply Theorem to clean skin, then seal with a moisturizer. The Grownup Moisturizer® is formulated to layer directly over it.

Can I use the mask with retinol or other actives?

Yes, though not in the same 15 minutes. Use the mask on clean skin as its own step, and keep applying any prescription treatment as your provider directs.
