If your skin is congested, oily, or just looking a little dull and uneven then this ingredient is for you. 🙌🏼✨✨
The Medik8 Niacinamide Peptides serum is one of those products that quietly does a lot. It’s built around 10% niacinamide (vitamin B3) which works to calm redness, balance oil, and support your skin barrier — so it’s brilliant for anyone who deals with congestion, enlarged pores, or that annoying combo of oily but somehow still sensitive skin.
What makes this one a step above is the peptide complex. Peptides are the building blocks that help stimulate collagen and elastin production, improving overall skin quality, while the niacinamide works away in the background on tone and texture.  The two together are genuinely a great team.
It also contains NAG (N-Acetyl Glucosamine) to gently exfoliate and even out skin tone, and 1% Zinc PCA to help regulate excess sebum  — so it’s doing a lot of the heavy lifting without any irritation.
Best suited for: oily, congested, blemish-prone, or uneven skin — but honestly, all skin types can benefit because it’s hydrating and barrier-supporting with a glowy, non-greasy finish. 
Use it morning or night, after your cleanser and before moisturiser. Simple. 👏🏼👏🏼👏🏼
