Niacinamide Peptides is the latest launch from the science-backed skincare brand, and new customers can currently bag 15% off
When Medik8 launches a new serum, expectations are naturally high. The brand has built its reputation on results-driven, science-first skincare, so when Niacinamide Peptides landed with promises of smoother texture, refined pores and a ‘glass-like’ glow in just seven days, I was eager to put it to the test.
On first impressions, the texture is lightweight and milky, so it feels instantly calming on the skin. A little really does go a long way, with one pump being more than enough to cover the entire face.
Despite the high 10% niacinamide content, it never felt greasy or irritating. Plus, it layers well with other products such as moisturiser and SPF without pilling or feeling heavy.
After 10 days of use, the most noticeable change has been in overall skin clarity and smoothness. My complexion looked more even, with a visible reduction in redness, particularly around the cheeks.
My skin texture, which is one of my main complexion concerns, feels more refined to the touch and one unexpected result was that there’s a subtle ‘tightening’ feeling, particularly on the forehead. I’ve also noticed fewer blemishes following a breakout the previous week, suggesting the zinc and niacinamide combination is doing its job when it comes to regulating oil and keeping congestion at bay.
Niacinamide Peptides
A clinically proven 10% niacinamide serum designed to help refine the look of pores and congested complexions for visibly smoother, clearer-looking skin.
While I wouldn’t say my skin has reached full-on ‘glass skin’ status just yet, there’s no denying an improvement in luminosity. My skin looks brighter, healthier and more balanced, with the serum slotting into my routine alongside other Medik8 favourites, such as the Press and Glow toner and C-Tetra Luxe serum.
While Medik8’s science-backed formula is undeniably impressive, Korean skincare is often revered for its ability to deliver glass-like skin, with products like the Biodance Bio Collagen-Real Deep Mask ideal for giving skin a much-needed boost before an event or occasion. A pack of four costs less than £15, and transforms from a serum-saturated gel mask to a transparent sheet mask, delivering moisture with a glass skin finish, according to LookFantastic.
For those seeking peptide-powered formulas, SkinCeuticals P-TIOX Anti-Wrinkle Serum comes in at £130. According to the brand, the potent serum leaves skin noticeably brighter, smoother and more radiant, reducing nine types of expression lines.
The Medik8 Niacinamide Peptides serum comes in considerably cheaper, though, costing £49 for a 30ml bottle. New customers can get 15% off their first order, which takes the total down to £41.65 for up to 80 uses, meaning it will last at least two months with daily use.
The product has so far earned a 4.7 star rating based on more than 260 reviews. One said: “Although I have dry ageing skin, I frequently suffer from blemishes on my chin. This product definitely helped clear my skin, but without any drying effect. It left my skin looking clearer and smoother.”
Another added: “I really enjoyed this Niacinamide Peptides Serum. The texture is lightweight and absorbs beautifully into the skin. After using it, my skin looked clearer and more refreshed. It’s gentle but effective, and I’ll definitely keep using it.”
However, some have expressed disappointment that Niacinamide Peptides had replaced the brand’s former Clarity Peptides, with one commenting: “Difficult to comment on the efficacy from a small sample. The texture was similar to the original clarity peptides, but I felt it left a sticky residue and it was unpleasant to wear under makeup. Overall, I prefer the original formulation, disappointed that it is being discontinued.”
But generally, people have been enjoying the latest formulation, with another adding: “I’ve just turned 40 and I have mild acne with first lines and wrinkles. This is a fantastic serum that addresses both, and compared to the previous formula, feels lighter and more compatible with a moisturiser. I’m a fan and can’t wait to buy the full-size version.”
Medik8’s latest Niacinamide Peptides is a product that slots easily into existing skincare routines, with the versatile ingredients working well with other products. It delivers visible, believable results over time rather than performing overnight miracles, but it’s certainly going to be one I continue to use over the next few months.
