FAQs FAQ

FAQs

  • Firming Plant Peptide Serum should be used on clean, dry skin—after a toner if you use one, and before moisturizer or SPF. Because peptides are most effective when applied directly to clean skin, we always recommend using Firming Plant Peptide Serum before Daily Vitamin C Serum if you’re layering both. This serum’s instant plumping effects make it perfect in the morning to prep your skin for the day, but it also works beautifully in the evening for overnight firming and hydration. 

  • This serum helps reduce visible signs of aging by helping plump, firm, and lightly hydrate. It’s an ideal choice if you’re noticing changes in your skin. 

  • In an in-vivo skin imaging study—measuring changes on real skin—the formula showed a 29% reduction in wrinkle appearance just 15 minutes after application. And in a 12-week consumer performance study of 45 participants ages 18 to 65, 93% said their skin appeared plumper and fuller.  

  • Daily Vitamin C Serum is a morning-specific serum that helps brighten and support collagen production, while Nightly Retinol Serum is an evening-specific serum that helps smooth texture and promote cellular turnover. Firming Plant Peptide Serum is an AM or PM serum that supports aging skin by harnessing plant-based ingredient technology for visible plumping, firming, and hydration. And yes—you can layer it with Daily Vitamin C Serum in your morning routine, then with Nightly Retinol Serum in your evening routine. Just apply Firming Plant Peptide Serum first in both routines, letting it absorb for 2–5 minutes before applying the next serum. 

  • Yes. This formula is highly effective on the neck and chest—helping visibly lift, smooth, and soften the look of fine lines. Just sweep a quarter-size amount of the serum upward from the décolleté to the jawline.
