SkinCeuticals Cell Cycle Catalyst Anti-Aging Serum 30ml / 1 fl oz NEW,

SkinCeuticals Cell Cycle Catalyst is an exfoliating booster serum formulated to accelerate skin renewal and enhance anti‑aging regimens. It uses a 7.7% multi‑acid complex (phytic, mandelic, salicylic and glycolic acids) to provide a gentle, multi‑level chemical peel that promotes cellular turnover at the skin surface. The formula also contains 1% taurine, an amino acid intended to support cellular energy and help maintain moisture and barrier function. Clinically tested to improve texture, tone and radiance, it reduces the visible appearance of fine lines, discoloration and enlarged pores while leaving skin hydrated and well tolerated for daily use. 

Directions: apply once daily after cleansing to dry skin (apply a small measured amount, then follow with antioxidant serums and moisturizer; in the morning use broad‑spectrum sunscreen). Avoid layering with other strong acids or retinoids without spacing applications; if irritation occurs, reduce frequency. Fragrance‑free, alcohol‑free and silicone‑free. Suitable for a range of skin types concerned with aging, uneven texture or dullness; tolerance and frequency should be adjusted for sensitized or highly reactive skin.
