What it is: An herbal alternative to retinoid formulas that gently revitalizes skin while you slumber without irritation, redness or peeling.

Who it's for: Anyone who wants to capitalize on skin's nightly renewal while avoiding retinoids.

What it does: It calms, smoothes and plumps skin's appearance to a radiant, creamy glow while refining and evening texture and tone and promoting the appearance of clear pores. Designed for use only at night, it also diminishes evidence of previous blemishes. It's formulated with fermented pumpkin enzymes which renew skin to a delectable softness and decrease the appearance of environmental overexposure with a gentle, refining exfoliation; an encapsulated, biomimetic peptide derived from yeast enhances the appearance of renewed plump, conditioned skin; and sea algae extracts which are lush, oceanic extracts studied for their impressive abilities to hydrate skin and recover an appearance of vibrant luminosity. Xylitylgulcosides, precursors to skin's natural creation of hyaluronic acid, enhance the appearance of a hydrated, plump complexion, and neroli, an organic aromatherapeutic treasure extracted from the blossoms of the bitter orange tree, soothes skin and nerves alike.

How to use: After sunset, apply 5–7 drops of serum to a clean face, neck and décolletage. In the morning, cleanse applied-to areas. Moonlight Catalyst must not be worn during the day or in conjunction with other exfoliating products or prescriptions to avoid irritation.
