Searching for a single ingredient that tackles multiple concerns without overwhelming the skin? Our 6% niacinamide serum delivers exactly that. Niacinamide (vitamin B3) is one of the most researched and dermatologist-recommended actives in modern skincare - celebrated for brightening, pore refinement, oil regulation, redness reduction and barrier repair. At 6%, this mid-strength concentration offers excellent clinical efficacy while remaining gentle enough for daily use, even on sensitive, acne-prone or reactive skin types.

Why 6% Niacinamide Is an Ideal Everyday Strength

Niacinamide works through multiple pathways: it inhibits melanosome transfer to fade hyperpigmentation, regulates sebum production to control oil and shine, reduces inflammation to calm redness and breakouts, supports ceramide synthesis to strengthen the skin barrier, and improves overall texture and elasticity. At 6% - a sweet spot between the very gentle 2-5% formulas and higher 10% options - it provides noticeable improvements in:

Pore size and skin smoothness

Brightness and evenness of tone

Reduction of dark spots, post-acne marks and mild hyperpigmentation

Oil balance and fewer congestion-related breakouts

Calmer, less reactive skin with improved resilience

Dermatological studies and widespread user feedback show that 5-10% niacinamide delivers significant visible results in 4-8 weeks, with continued improvement in clarity, radiance and barrier function over time. The 6% level is especially popular in the UK for being effective yet low-risk - rarely causing purging or irritation, and compatible with most other actives.

How to use :

After cleansing and applying a treatment tonic, apply 2-3 drops to face and neck. Gently pat in until absorbed, then follow with moisturiser. Use AM and/or PM - many prefer it in the morning for all-day brightness and oil control, or at night for repair. It is gentle enough for daily use from day one for most people. Always apply broad-spectrum SPF 30+ in the daytime. Pairs wonderfully with hyaluronic acid, peptides, ceramides or gentle retinoids; introduce stronger actives slowly if needed.
