Use once daily after cleansing, either morning or evening.

Apply approximately one-third of a dropper to clean, completely dry skin. Smooth evenly over the face, avoiding the eye and lip areas.

When used in the morning, apply Cell Cycle Catalyst before a SkinCeuticals antioxidant serum. Follow with moisturiser and broad-spectrum SPF50+ sunscreen.

Sensitive or active-naive skin should begin with two to three applications weekly before gradually increasing use as tolerated.

Although SkinCeuticals tested the formula alongside established anti-ageing routines that included retinoids, individual tolerance varies. Introduce cautiously and alternate with retinol if dryness or irritation develops.

7.7% Multi-Acid Complex

A combination of glycolic, phytic, lactic, mandelic and salicylic acids that provides multi-level exfoliation to improve surface renewal, texture, tone, pores and visible discolouration.

Glycolic Acid

An alpha hydroxy acid that helps remove accumulated surface cells and improve dullness, rough texture and visible fine lines.

Lactic Acid

An alpha hydroxy acid that provides exfoliating and moisture-supporting benefits.

Mandelic Acid

A larger-molecule alpha hydroxy acid that supports more even-looking tone and texture.

Phytic Acid

Provides antioxidant, clarifying and complementary exfoliating support.

Salicylic Acid

An oil-soluble beta hydroxy acid that helps clear surface congestion and refine the appearance of pores and blemish-related marks.

1% Taurine

An amino acid used to support cellular vitality, surface renewal and skin moisture retention.

Glycerin

A humectant that attracts water to the skin and helps maintain hydration during exfoliation.
