Paula's Choice Pro-Collagen Multi-Peptide Booster - 5ml

Yes, this booster is compatible with retinol and can be layered for enhanced anti-aging benefits.

Yes, it is formulated to be gentle and is suitable for all skin types, including sensitive skin.

Depending on usage, the 5ml size is a travel-friendly version that typically lasts 1-2 weeks with daily application.

No, this is a concentrated booster, not a moisturizer; you should apply your regular moisturizer afterward to seal in hydration.

You may see an immediate plumping effect, but significant firming and structural improvements usually become visible after 4-8 weeks of consistent use.

Apply less product and allow the booster to fully absorb for 2-3 minutes before applying makeup or sunscreen.

This is often normal with active peptides, but if irritation persists, reduce usage to every other day until your skin builds tolerance.
