PROVEN SkinSpecific routines are complete solutions on their own, but they’re also designed to work well with other products. You can safely mix and match to address changing skin needs, though we recommend starting with one routine first to gauge your skin’s response, making adjustments as desired.

SkinSpecific provides targeted routines focused on a single primary concern. The Anti-Aging Routine uses science-backed ingredients selected to help support smoother, more youthful-looking skin. PROVEN Pro is fully personalized and adapts to your unique skin profile and environment, helping address multiple concerns at once.

We recommend keeping your routine simple. The Anti-Aging Routine already includes ingredients selected to support smoother and more radiant-looking skin. If you want to add additional treatments, introduce them gradually to avoid irritation.

Yes, the Anti-Aging Night Cream contains Hydroxypinacolone Retinoate, a retinoid ester known for its ability to support a more refined and resilient-looking complexion. The Cleanser and SPF are retinoid-free. If you use additional retinoid products, we recommend adding them gradually to avoid potential dryness or sensitivity.

With consistent use, each product typically lasts 6–8 weeks. This may vary depending on how much you apply.
