Medicube's bestselling NAD EGF Firming Serum is now available on Amazon for £16.90, down from £18.90. The lightweight K-beauty serum, designed for the face and neck, targets fine lines and aims to improve skin firmness.
The formula combines collagen extract with NAD+ and EGF, ingredients used in skincare to target firmness, fine lines and radiance. Together, they are intended to help the skin maintain elasticity while giving it a smoother, more radiant appearance.
Shopper results within three weeks
The serum has received positive feedback, with some users reporting visible results within three weeks. One shopper said: "This inexpensive Medicube serum is by far the best I have ever used. I've spent up to £80 on other serums, and this is amazing."
Another added: "After three weeks, I could really tell the difference. I'm in my 60s. Highly recommend this and all the other Medicube products."
Clinical test data
Beyond customer reviews, the product is backed by clinical test results. A test conducted by the Global Institute of Dermatological Sciences found that visible smile lines decreased by 8.7% after two weeks, while visible neck lines decreased by 5.38% over the same period.
Mixed feedback and alternatives
While many shoppers praised the serum, one mixed review noted: "The Medicube collagen face mask is brilliant, so I thought I'd give this a try. Not seen much difference with this, and it is a little sticky."
For those seeking alternatives, COSRX's 6 Peptide Skin Booster Serum (£23, Boots) packs six different peptides to boost elasticity and refine pore texture. The Nip + Fab Peptide Fix Finishing Serum 2% (£29.95, Sephora) uses a 2% peptide complex with copper peptides to tighten and smooth the jawline and neck.
