Technique & Craft
Sebum production is regulated primarily by androgens (dihydrotestosterone / DHT). In sebocytes, the enzyme 5-alpha reductase converts circulating testosterone into active DHT, stimulating the synthesis of triglycerides and squalane.
Zinc PCA acts as a competitive inhibitor of 5-alpha reductase, directly downregulating sebaceous gland lipid secretion. Furthermore, the pyrrolidone carboxylic acid (PCA) component is a native constituent of human Natural Moisturizing Factor (NMF), ensuring that oil reduction does not result in barrier dehydration.
Niacinamide increases cellular levels of nicotinamide adenine dinucleotide (NAD+/NADH), boosting ATP production within keratinocytes. This accelerates epidermal cell differentiation, helping pores shed dead skin cells cleanly rather than clumping into blackheads.
By stimulating the cutaneous biosynthesis of ceramides and sphingolipids, niacinamide tightens the structural collagen fibers surrounding the follicular infundibulum. This prevents pores from stretching out under heavy oil production, visibly smoothing skin texture.

True niacinamide does not accelerate cellular turnover like retinoids or AHAs, so it does not cause biological purging. However, very high concentrations (10% to 20%) can cause temporary flushing or irritation in sensitive skin. If you experience irritation, try a gentler 2% to 5% formula.
Yes! Modern dermatological research proves that niacinamide is chemically stable with both vitamin C and retinol. In fact, layering niacinamide before retinol is highly recommended because it strengthens the skin barrier and reduces retinoid irritation.
Surface oil reduction and T-zone shine control typically improve within 3 to 5 days. Structural reduction in pore size and fading of post-acne marks generally take 4 to 8 weeks of consistent twice-daily use.
