TEN ZERO PDRN Collagen Hidden Shot 30ml — skin repair booster

Niacinamide + adenosine: certified brightening & wrinkle-care essence

Korean cosmetic regulations (MFDS) certify specific actives for functional skincare claims. Two of the most well-studied are niacinamide — certified for brightening/melanin reduction — and adenosine — certified for wrinkle improvement. TEN ZERO's PDRN Collagen Hidden Shot formulates both as the primary efficacy drivers in a daily-use essence, alongside centella complex, retinol, panthenol, and sodium hyaluronate. The formula additionally contains Sodium DNA (5 ppm) and Hydrolyzed Collagen (2 ppm) at trace concentrations — ingredients that give the product its branding, present at ppm level in the formula.

How the actives work

Niacinamide sits as the 5th ingredient by weight — a high-loading position — and works by blocking the transfer of melanin from pigment cells (melanocytes) to surface skin cells (keratinocytes), reducing the appearance of dark spots and uneven tone. Adenosine, MFDS-certified for wrinkle improvement, acts on skin repair signalling pathways and supports collagen synthesis. The centella asiatica complex (Centella Asiatica Extract, Madecassoside, Madecassic Acid, Asiaticoside, Asiatic Acid) provides barrier-calming and anti-inflammatory support alongside panthenol, and retinol assists with cell turnover at its supporting concentration.

Frequently asked questions

Why is this called a "PDRN Collagen Hidden Shot" if the primary actives are niacinamide and adenosine?

The product name and branding reference sodium DNA (marketed as "PDRN") and hydrolysed collagen, both of which are real ingredients present in the formula at trace concentrations (5 ppm and 2 ppm respectively). However, at ppm-level concentrations, the primary efficacy drivers are niacinamide and adenosine, which appear at significantly higher positions in the ingredient list. Korean cosmetic branding commonly highlights trace specialty ingredients in product names — the "hidden shot" framing reflects their inclusion, not their concentration.

What does niacinamide actually do for skin tone?

Niacinamide (vitamin B3) works by blocking the transfer of melanin from pigment cells (melanocytes) to surface skin cells (keratinocytes). Skin develops dark spots partly because this transfer deposits pigment into cells that reach the surface. By interrupting that transfer, niacinamide prevents new spots from forming and gradually reduces the pigmentation of existing ones as pigmented surface cells shed naturally. At a high loading position in the formula, this effect is consistent with regular use — typically visible at 4–6 weeks.

Can I use this right after a skin treatment (laser, peel, microneedling)?

Niacinamide and centella asiatica are both suitable for post-procedure recovery. Niacinamide's anti-inflammatory properties help calm post-treatment redness, while centella supports barrier repair. Wait until the skin is no longer raw or open — typically 24–48 hours post-procedure — before beginning use. Note that this formula contains retinol; in the first 1–2 weeks of post-procedure recovery, use with care and reduce to evenings only until skin has healed.

How does this work alongside other brightening actives?

Niacinamide is well-tolerated alongside most brightening actives. If you're using a vitamin C serum, apply it first (it performs better at lower pH), allow it to absorb, then apply this serum. Niacinamide is fully compatible with retinol when applied in the same routine. The centella complex in this formula also complements acid-based exfoliants used on alternating evenings.
