Medik8 Liquid Peptides review *Unsponsored*
If you’ve been curious about Medik8 Liquid Peptides, here’s everything you need to know and my honest, unsponsored review.
I bought this product myself, this is not sponsored in any way.
What is Medik8 Liquid Peptides?
Medik8 Liquid Peptides is a high-performance daily serum designed to target and prevent fine lines and deeper wrinkles.
It contains an impressive 30% concentration of 10 powerful peptides that work together to smooth, firm and strengthen the skin over time.
The formula also includes hyaluronic acid to deeply hydrate and leave your skin looking plump and refreshed.
You can apply this serum in the morning and evening and it’s completely compatible with Medik8 Crystal Retinal.
What is Medik8 Liquid Peptides so effective?
Peptides are some of the most effective ingredients for improving skin texture and resilience, and Medik8 takes this to the next level.
This serum doesn’t just contain one or two peptides, but 10 highly concentrated peptides to maximise results.
It also uses advanced drone-targeted delivery technology to ensure the active ingredients reach the areas of your skin where they’re needed most. This means every drop works harder to deliver visible improvements.
What are the key ingredients in Medik8 Liquid Peptides?
Here’s a breakdown of the key peptides inside this formula:
Matrixyl 3000: Boosts collagen production for firmer, plumper skin
Copper Peptides: Supports skin regeneration and improves elasticity
Expression Line Peptides: Help to relax facial tension and soften expression lines
Carnosine: Protects against glycation which can damage collagen and accelerate ageing
Where to buy Medik8 Liquid Peptides online?
You can order Medik8 Liquid Peptides on Medik8 website as well as several beauty e-retailers including Cult Beauty and Sephora.
The RRP is £55, but discounts are available every now and then.
Medik8 Liquid Peptides unsponsored review
At the time of writing this post, I’m just finishing my first bottle of Medik8 Liquid Peptides and I’ve already decided to repurchase it.
June 2025 edit: Over a year after writing this review, this serum is still a staple in my skincare routine, I use it every day!
How I’ve been incorporating Medik8 Liquid Peptides into my routine
I use this serum twice a day, morning and evening, right after cleansing.
In the morning, I follow it with a Vitamin C moisturiser. In the evening, I apply it before my Medik8 Crystal Retinal serum.
What I love about Medik8 Liquid Peptides
Here’s why I’ve been so impressed with this serum:
Silky, fast-absorbing texture: It feels lightweight and smooth and sinks in beautifully without leaving residue. I love taking a moment to massage it in, as it encourages circulation and boosts absorption.
Powerful multi-tasking formula: I’m now all about using fewer but more effective products. This serum tackles multiple signs of ageing in one step which makes it a staple in my routine. My skin already looks smoother and feels more resilient.
Compatible with the rest of my skincare: It layers well with other serums like Crystal Retinal, so I didn’t have to overhaul my routine to fit it in. It simply works alongside the products I already love.
Is Medik8 Liquid Peptides worth the price?
While it might seem pricey at first, a little really does go a long way. Using just a few drops twice a day, one bottle has lasted me several months.
Given the high concentration of clinically proven peptides, the advanced delivery system and how well it works for me, I consider it a smart investment in my skin.
If you’re looking for a peptide serum that delivers real results and fits seamlessly into your routine, I highly recommend giving Medik8 Liquid Peptides a try.
