Frequently Asked Questions

What does a caffeine and peptide serum do?

This lightweight serum is formulated for the look of the eye area and surrounding skin. Caffeine and peptides help the area appear fresher, smoother and more awake, softening the look of shadowing and tired-looking skin. It absorbs quickly and sits comfortably under makeup.

How do I apply it around the eyes?

Use a small amount and tap it gently along the orbital bone with your ring finger, staying clear of the lash line and avoiding direct contact with the eyes. Let it absorb fully before applying moisturiser or makeup. Use morning and evening for the most consistent look.

How long before I see a difference?

Skincare works gradually. Most people look for a visible difference in the appearance of the area over four to eight weeks of consistent daily use. Results vary between individuals. Using it morning and evening, alongside good sleep and sun protection, gives the most noticeable outcome.

Can I use it with my other serums?

Yes. Apply it before heavier serums and moisturiser so the lightweight texture absorbs properly. It layers comfortably with hydrating and antioxidant products. If you are also using vitamin A near the eye area, introduce products one at a time so the skin can adjust.
