✓ 10% Niacinamide + 3% Crystalide Peptide + 1% Zinc PCA | ✓ Clinically Shown: 35% Fewer Visible Blemishes | ✓ Visibly Clearer, Smoother Skin in 7 Days

Medik8 Niacinamide Peptides is the successor to Medik8's much-loved Clarity Peptides: a multi-active emulsion serum powered by 10% niacinamide, a 3% Crystalide peptide and 1% zinc PCA, clinically shown to reduce visible blemishes by 35% while soothing the skin barrier. It is the niacinamide serum for enlarged pores, congestion and blemish-prone skin that wants a clearer, smoother, glass-like finish.

Niacinamide (vitamin B3) visibly calms blemish-related redness while hydrating and supporting the skin's natural barrier. The 3% Crystalide peptide works to enhance skin cell renewal for a more uniform, luminous-looking surface, N-acetyl glucosamine gently exfoliates and boosts the niacinamide, zinc PCA helps keep excess oil in check and hyaluronic acid keeps the skin plump. In Medik8's independent four-week clinical study on 30 participants there was a 35% reduction in visible blemishes, a 26% reduction in visible pore size and a 34% improvement in the skin barrier, with 100% showing an improved barrier within 7 days. In the consumer study, visible redness was reduced in 7 days, 94% agreed Medik8 Niacinamide Peptides was gentle and 100% said it layered well in their routine.

With over 20 years in specialist skincare and medical aesthetics, Becci - the aesthetics nurse who founded Adore Your Skin - hears more questions about pores and breakouts than almost anything else, and clients value that she gives a straight answer. Medik8 Niacinamide Peptides is the one she recommends because it clarifies without stripping: a clinically studied 10% niacinamide that improves the barrier instead of challenging it.

FAQS

Is Medik8 Niacinamide Peptides good for blemish-prone skin and large pores? +

That is exactly what it is built for. In Medik8's independent four-week clinical study it delivered a 35% reduction in visible blemishes and a 26% reduction in visible pore size, with visibly clearer skin and smoother texture in 7 days. It balances oil with zinc PCA rather than drying the skin out, so it suits combination and sensitive skin too.

Is Medik8 Niacinamide Peptides the same as Clarity Peptides? +

It is the next generation rather than the same product. Medik8 describes Niacinamide Peptides as building on everything customers loved about Clarity Peptides, and its old Clarity Peptides page now points to this one. Both are 10% niacinamide emulsions with the Crystalide peptide, zinc PCA, N-acetyl glucosamine and hyaluronic acid, but Niacinamide Peptides is a new formula with stated 3% Crystalide and 1% zinc PCA levels and a full set of clinical results behind it.

Can I use Medik8 Niacinamide Peptides with Crystal Retinal or retinol? +

Yes. Medik8's evening layering puts Niacinamide Peptides straight after cleansing, then Crystal Retinal, then moisturiser. Niacinamide's barrier support makes it a comfortable partner for vitamin A.

Do I apply it before or after vitamin C? +

It depends on the texture of your vitamin C. Oil-based C-Tetra and C-Tetra Luxe go on first, then Niacinamide Peptides. With a water-based or gel vitamin C, apply that first, then Niacinamide Peptides, then sunscreen.

Can I layer Niacinamide Peptides with Liquid Peptides Advanced MP? +

Absolutely. Both are lightweight emulsions, and Medik8 recommends following the thinnest-to-thickest rule: Niacinamide Peptides is slightly thinner, so apply it first and Liquid Peptides Advanced MP on top.

Will 10% niacinamide irritate sensitive skin? +

Medik8's data suggests not: 94% of consumer-study participants agreed it was gentle, 100% of clinical participants showed an improved skin barrier within 7 days, and it is fragrance free, alcohol free, non-comedogenic and dermatologically tested. Patch test first as with any new active.

Should I use it in the morning or evening? +

Either or both. Medik8 says it can be used after cleansing day or night; most people use it twice a day for the fastest visible results on pores and blemishes.

How quickly will I see results? +

Medik8's studies showed visibly clearer skin, smoother texture and reduced visible redness within 7 days, with the full 35% reduction in visible blemishes and 26% reduction in visible pore size measured at 4 weeks.

Can I use Medik8 Niacinamide Peptides during pregnancy or while breastfeeding? +

It contains no vitamin A, which is the ingredient most people are asked to avoid. Medik8 does not publish formal pregnancy or breastfeeding guidance: as a cosmetics company it says it cannot advise on medical conditions and asks customers to discuss the full ingredient list with their midwife or GP before use. Its only general note is that the formula contains no ingredients it would recommend avoiding in pregnancy unless your doctor advises otherwise. Please check with your midwife or GP first.
