The other brightening and hydrating ingredients also give you a serious glow.”

FAQ

How does Renewal Serum work?

The formula combines encapsulated lactic and glycolic acids with growth factor–mimicking peptides, antioxidants, and hydrating actives. The acids dissolve the bonds between dead skin cells, revealing smoother, brighter skin beneath. Growth factor–mimicking peptides stimulate skin’s natural repair processes and support collagen renewal, while antioxidants and ceramides reinforce the barrier to keep skin balanced.

How is Renewal Serum different from Retinol Serum?

Retinol Serum works primarily through retinoid receptors to accelerate cell turnover and refine texture. Renewal Serum uses exfoliating acids for resurfacing, supported by growth factor-mimicking peptides and barrier-strengthening actives for hydration and repair. Retinol Serum is best for targeting lines, wrinkles, and overall firmness; Renewal Serum excels at improving texture, radiance, hydration, and more advanced collagen support.

How is Renewal Serum different from Composition No. 1?

Composition No. 1 is a multi-corrective treatment for deep structural repair. Renewal Serum, by contrast, is gentler, focusing on resurfacing with acids and skin regeneration through growth factor–mimicking peptides. Renewal Serum can typically be used more frequently in a daily routine, and can be alternated with Composition No. 1 to create a balanced evening routine.

Can Renewal Serum be layered with other serums?

Yes. Renewal Serum pairs well with other serums. It can be applied over Line Serum (for additional tightening and improvements in laxity and surface lines). It should not be combined in the same routine with Retinol Serum or Composition No. 1 to avoid over-exfoliation.

Is Renewal Serum suitable for sensitive skin?

Yes, but start gradually. Those with reactive skin may prefer to apply 2–3 times per week before moving to more frequent use.
