SkinCeuticals Cell Cycle Catalyst

A gentle resurfacing serum designed to improve tone, texture, and radiance by supporting consistent skin renewal.

Cell Cycle Catalyst is a nightly treatment that helps optimize the skin’s natural exfoliation process. By encouraging controlled cell turnover, it improves the appearance of discoloration, dullness, and uneven texture while helping prepare the skin to better tolerate corrective treatments over time.

Unlike aggressive exfoliants, this serum is designed for long-term use, making it especially valuable for skin prone to pigmentation, melasma, or sensitivity.

Why It’s Different

Cell Cycle Catalyst focuses on regulating renewal rather than forcing it.

By supporting a steady exfoliation rhythm, it helps:

• Improve uneven tone and radiance

• Smooth rough or textured skin

• Enhance the performance of other corrective products

• Reduce irritation often associated with stronger exfoliating treatments

This makes it an ideal option for patients who need visible results without compromising the skin barrier.

Who This Product Is Best For

• Uneven tone or dullness

• Melasma-prone or pigmentation-prone skin

• Rough texture or visible congestion

• Skin preparing for or maintaining results from corrective treatments

Pregnancy use should be reviewed with a provider.

When to use

• Evening use preferred

• 3–4 nights per week to start

• May increase frequency as tolerated and directed by your provider

Where it fits in your routine

• Apply after cleansing

• Use as your targeted treatment step

• Follow with hydration and moisturizer

On nights when Cell Cycle Catalyst is used, it should typically be the only exfoliating or corrective active applied.

How much to use

• 1 pump

• Apply evenly to face and neck
