FAQS

What's the difference between Niacinamide Peptides and Clarity Peptides? +

Niacinamide Peptides is the upgraded, reformulated version of the previous Clarity Peptides formula. It builds upon everything customers loved about Clarity Peptides while delivering enhanced efficacy.

Key improvements include:

Stronger clinical evidence with independent trials
Addition of NAG (N-Acetyl Glucosamine) for enhanced brightening
Improved texture that's even more lightweight and fast-absorbing
Better results in shorter timeframes (visible improvements in 7 days)

If you loved Clarity Peptides, you'll love Niacinamide Peptides even more.

Can I use niacinamide with vitamin C? +

Yes – despite outdated advice suggesting otherwise, niacinamide and vitamin C work beautifully together. Modern formulations are stable and compatible.

For layering: If using with an oil-based vitamin C like C-Tetra Luxe, apply the vitamin C first (oil-based), then Niacinamide Peptides (emulsion-based). If using with a water-based vitamin C, apply the thinner texture first.

How quickly will I see results? +

Clinical trials show visible improvements begin within 7 days:

Week 1: Visibly clearer skin, smoother texture, reduced redness
Week 2-3: Continued improvement in blemishes and overall clarity
Week 4: 35% reduction in visible blemishes, 26% reduction in pore size, significantly healthier skin barrier

The glass-like glow effect is often visible immediately after application due to the light-reflecting peptide technology.

Is this suitable for sensitive skin? +

Yes – 94% of users agree it's gentle on the skin. The formula is:

Fragrance-free
Non-comedogenic
Clinically proven gentle
Designed to support (not compromise) skin barrier health

Niacinamide itself is known for its calming, anti-inflammatory properties, making this suitable for sensitive and reactive skin types. However, we always recommend patch testing before first use.

Can I use Niacinamide Peptides with retinol or retinal? +

Absolutely – this is actually an excellent combination. Use Niacinamide Peptides in your morning routine (with vitamin C and SPF) and your vitamin A product (Crystal Retinal or Intelligent Retinol) at night. This follows Medik8's CSA Philosophy and gives you comprehensive skin improvement:

Morning: Niacinamide for clarifying, barrier support and oil control
Evening: Vitamin A for anti-ageing and cell renewal

How does this compare to The Ordinary Niacinamide? +

While The Ordinary offers affordable niacinamide, Medik8 Niacinamide Peptides delivers a more sophisticated, clinically proven formula:

Added peptide technology (3% Crystalide™) for radiance and cell renewal
Zinc PCA for active sebum regulation
NAG for gentle exfoliation and enhanced brightening
Independent clinical trials with measurable results
Elegant texture that layers beautifully without pilling

For those wanting proven results beyond basic niacinamide, this is the upgrade.

Is Niacinamide Peptides safe to use during pregnancy and breastfeeding? +

Niacinamide Peptides does not contain any ingredients that Medik8 would recommend avoiding during pregnancy or breastfeeding. However, as with all skincare during this time, we recommend discussing the ingredients with your GP or midwife before use for personalised advice.
