Medik8 20% off sale includes 'Botox in a bottle' anti-ageing serum
'People ask if I've had Botox or fillers, and I say no, it's the amazing products of Medik8'
Medik8 has carved out a reputation for its effective, high-performance skincare, winning over beauty editors, skincare professionals and fans alike. But while the products pack a punch, they can also come with a price tag, with some of its bestselling formulas reaching up to £99 a bottle.
So I was pleased to spot a rare 20% off sale across the site, including one of its most buzzed-about serums: the Liquid Peptides Advanced MP, which is now £63.20 down from £79. Described as 'Botox in a bottle' by shoppers, it's clinically proven to lessen the appearance of expression lines in 10 minutes and deep-set wrinkles within eight weeks.
The brand claims that the multi-peptide complex provides a 'filler-like effect' while also supporting long-term collagen production. Judging by the reviews, it's clearly working - the product has racked up an impressive 4.9-star rating with shoppers.
One reviewer said: "Using it morning and night, my skin looks and feels nourished, plumper and smoother. Using Medik8 products has significantly improved my skin. People ask if I've had Botox or fillers, and I say no, it's the amazing products of Medik8."
Another chimed in: "This product is unbelievably effective. Almost overnight, my wrinkles smoothed out and my skin had an amazing glow, never before achieved with a topical product. I am now about a quarter through my first bottle, and I can honestly say the difference is remarkable."
However, someone else said: "Too runny, and no noticeable improvement. Nothing special."
For those curious about peptides but want to explore other options, there are several highly rated alternatives available. The Ordinary's Multi-Peptide + HA Serum (£15.90) is a budget-friendly favourite that combines peptides with hydrating hyaluronic acid.
Otherwise, Paula's Choice Pro-Collagen Multi-Peptide Booster (£46.40, originally £58) is a silky booster that can be mixed into moisturiser or used alone to improve firmness and fine lines. It has been clinically proven to visibly smooth lines in 15 minutes and visibly firm, plump, and reduce wrinkles in a month.
Back to the Medik8 sale, another standout is my personal favourite: C-Tetra Luxe, down to £47.20 from £59. This vitamin C serum is a staple in my morning routine thanks to its fast-absorbing texture and visible brightening effects.
Medik8 uses a stabilised form of vitamin C called tetrahexyldecyl ascorbate, which they claim delivers visible radiance after just one use. It also has a strong 4.9-star rating, proving its effectiveness.
A shopper wrote: "Amazing results. My skin feels refreshed, I use this every morning and it has improved the dark marks on my skin and made my skin look more even toned, and it has improved the brightness of my skin."
Someone else left a mixed review, noting: "I love this product. It makes my skin look bright and firm. However, this serum is quite oily for my combined skin type, so I use 2-3 drops only during the cold season."
Someone else added: "Love this stuff. It's been a game-changer for my skin. It is oily when first applied, but is quickly absorbed, leaving skin glowing and not greasy at all. Had little dry patches and this has sorted that as well as added a brightness to new skin. And it smells gorgeous."
