When Medik8 launches a new serum, it’s never just hype — it’s backed by serious science. Medik8 Niacinamide Peptides is the brand’s latest innovation, designed to calm stressed skin, refine texture and strengthen the skin barrier using a powerful blend of 10% niacinamide and peptides.
If redness, uneven tone or compromised skin comfort are top of your skin concerns, this is one launch worth paying attention to.
Why Medik8 Niacinamide Peptides Is Different
This isn’t a basic niacinamide serum. Medik8 Niacinamide Peptides is a next-generation Niacinamide Peptide Serum that targets skin at a deeper level, focusing on redness recovery, long-term resilience and smoother texture.
By pairing high-strength niacinamide with skin-supporting peptides, it helps to:
Calm visible redness and sensitivity
Strengthen the skin barrier and improve skin comfort
Refine skin texture and support a clearer-looking complexion
Promote healthier, more balanced skin over time
It’s especially well suited to skin that feels reactive, stressed or easily overwhelmed by active ingredients.
The Key Ingredients Explained (Without the Jargon)
10% Niacinamide
A multitasking vitamin that helps balance excess oil, visibly reduce redness and improve uneven skin tone. At this strength, it’s ideal for compromised or blemish-prone skin while still supporting long-term skin health.
Skin-Supporting Peptides, Including crystalide™ peptide
Peptides act as messengers in the skin, helping support repair processes and collagen synthesis. Medik8’s inclusion of crystalide™ peptide helps promote smoother skin texture and a more refined, glass-like appearance over time.
Zinc PCA
Zinc PCA works alongside niacinamide to regulate oil production and support redness recovery. It’s particularly beneficial for skin that experiences congestion or shine, helping to keep pores clearer and skin more balanced.
N-Acetyl Glucosamine
A skin-identical ingredient that supports gentle resurfacing while encouraging the skin’s natural production of hyaluronic acid. This helps improve skin comfort, hydration levels and overall resilience.
Together, these advanced ingredients help move skin towards calm, refined, glass-like skin without compromising the skin barrier.
How to Use It in Your Routine
Use morning and evening after cleansing.
Apply 1–2 pumps to face and neck
Follow with moisturiser
In the morning, always finish with SPF
If you’re new to active skincare, this serum is an excellent way to strengthen the skin barrier before introducing more targeted treatments.

Frequently Asked Questions
Can I use niacinamide with Medik8 peptides?
Yes. Medik8 Niacinamide Peptides is specifically formulated to combine both, supporting redness recovery, skin comfort and barrier strength in one step.
Do peptides work with niacinamide?
They do. Niacinamide improves overall skin balance, allowing peptides to work more effectively to support repair, resilience and elastin production.
What should you never mix niacinamide with?
Niacinamide is generally very versatile. If your skin is sensitive, avoid layering it at the same time as very strong exfoliating acids.
Which is better, 10% or 5% niacinamide?
10% niacinamide, as used here, is more effective for visible redness, uneven tone and blemish-prone skin. Lower strengths may suit very sensitive skin.
What should I not mix with peptides?
Peptides work best on calm skin. Avoid applying them immediately after strong acids to ensure maximum effectiveness.
