Collection: numbuzin

numbuzin organises its product range using a clear numbered system: each number indicates a specific function or category in a skincare routine. No.1 covers cleansing and hydration basics; No.2 is for plumping and overnight repair; No.3 is for pore care and refining; No.5 is for brightening and dark spot care (Glutathione line); No.9 is for advanced anti-aging (NMN line). The numbered system makes it easy to build a complete routine from the brand and to identify which product addresses which concern at a glance.

'Bio-retinol' typically refers to a plant-derived retinoid alternative (often bakuchiol or sea fennel extract) that mimics the effects of retinol on skin — smoothing fine lines, refining pores, supporting cell turnover — but without the irritation, photosensitivity or pregnancy contraindications of retinol. The No.3 Blue Bio-Retinol Pore Refining Serum is suitable for users who can't tolerate traditional retinol, are pregnant or breastfeeding, or simply prefer plant-based alternatives. Apply morning and evening on clean toned skin. Visible pore refinement and smoother texture in 4–8 weeks.

The No.5 Glutathione line combines two powerful brightening actives: glutathione (a tripeptide antioxidant that inhibits melanin production) and tranexamic acid (a clinical brightening compound that blocks the inflammation-to-pigmentation pathway). Together, they target stubborn dark spots, melasma, post-acne marks and overall uneven tone. The line includes the Glutathione TXA Ampoule (intensive treatment) and the Glutathione Vitamin Tone Up Sun Serum (daily SPF with built-in brightening). Use both together for comprehensive day-and-night brightening protection.

NMN (Nicotinamide Mononucleotide) is a precursor to NAD+ — a coenzyme involved in cellular energy production and DNA repair that naturally declines with age. NMN has gained attention in longevity research for its potential to support cellular health. In skincare, NMN is used as an advanced anti-aging active that supports skin cell regeneration, energy and resilience. The numbuzin No.9 line (NMN+BIO Lifting Sil Essence, NMN Retinol Volumetox Eye Cream, NMN+Collagen Under Eye Patches) targets mature skin needing deep anti-aging support beyond standard peptide creams.

Typical AM routine: cleanse → numbuzin No.3 Blue Bio-Retinol Pore Refining Serum (or rotate with No.5 Glutathione Ampoule) → moisturiser → numbuzin No.5 Glutathione Tone Up Sun Serum (SPF + brightening final step). PM routine: cleanse → numbuzin No.2 Rose PDRN Overnight Collagen Mask (2–3 nights per week as treatment) → numbuzin No.9 NMN Lifting Essence (anti-aging) → night cream → No.9 NMN Retinol Eye Cream. Don't stack too many actives the same night — alternate Glutathione Ampoule and NMN Essence on different evenings.
