Frequently Asked Questions
What does Cell Cycle Catalyst do?
It is a daily exfoliating serum powered by a 7.7% alpha and beta hydroxy acid complex plus 1% taurine. It gently boosts surface cell turnover to smooth texture, even the look of tone, and soften the appearance of fine lines.
How and when do I apply it?
Once daily, in the morning or evening after cleansing, apply about one-third of a dropper to dry skin with your hands. Using it as an early step helps prime skin for the rest of your routine.
Can I use it with my retinol?
In studies it was well tolerated layered over anti-aging routines, including retinol. If your skin feels sensitive, you can separate them by using one in the morning and the other at night, or alternate nights.
Can it help me prepare for a professional peel?
Yes, it is often used to prime skin ahead of in-office chemical peels. Check with your provider about the right timing before your appointment.
Do I need sunscreen while using it?
Yes. Exfoliating acids can make skin more sensitive to the sun, so daily broad spectrum sunscreen is important while using this serum.

This is a great addition to my evening routine to use on the nights when I am not using Tretinoin cream. Currently using once or twice a week and happy about it. I used a sample before and invested in the full bottle. My only worry is the dropper being destroyed for staying in the acidic solution for a long time since the bottle came with the dropper attached so I don't have a separate cap for the bottle if I wanted to take the dropper out.

I used the Skinceuticals Cell Catalyst in preparation for a CO2 laser treatment. I healed really fast, and I think the Cell Catalyst played a part in my healing so fast.
