Medik8 has reduced the price of its Liquid Peptides Advanced MP serum from £79 to £63.20, a 20% saving. The formula, nicknamed 'Botox in a bottle' by shoppers, is clinically proven to soften expression lines in 10 minutes and smooth deep-set wrinkles in eight weeks.
How it works
The serum uses a multi-peptide complex designed to deliver a filler-like effect while boosting long-term collagen production. Specialised MiniProteins target dynamic lines and support skin structure for a firmer, smoother complexion.
Shopper reviews
The product has a 4.9-star rating from over 5,300 reviews. One customer said: "Game changer, this serum is a miracle worker and has transformed my 60-year-old skin. I use it every evening, and my skin is smooth and lifted by morning." Another commented: "Since incorporating it into my skincare routine, I've noticed a remarkable difference. My skin is so incredibly smooth and refined."
A third reviewer noted: "This product literally works like magic. On the first application, my skin felt smoother and more hydrated. Weeks on and wrinkles are less defined, making me feel more confident." However, a three-star review said: "I do find the consistency very watery."
Alternative options
For different budgets, Paula's Choice Pro-Collagen Multi-Peptide Booster (£58, Cult Beauty) can be blended into moisturiser or used alone. The Ordinary Multi-Peptide + Hyaluronic Acid Serum (£15.90, Boots) aims to improve skin texture and firmness.
One Medik8 fan added: "The Liquid Peptides serum has such a lightweight, silky texture that absorbs beautifully without feeling sticky or heavy. After a few weeks, my skin started looking noticeably smoother, more hydrated, and plumper - especially around my smile lines and forehead."
