Skin 1004's answer to the question every retinol user has asked: why doesn't my serum absorb deeply enough?

The Retinol 0.2 Boosting Shot Ampoule uses micro-spicules — microscopic sea sponge-derived needles averaging 13μm in size, smaller than the average pore — to create temporary micro-pathways in the skin's surface that drive active ingredients 132.8% deeper than spicule-free formulas. The stretchy, elastic ampoule texture wraps tightly to skin for prolonged contact. Dual retinoids: 0.2% retinol plus retinal in the same formula. Madagascar centella and madecassoside cushion the retinol experience. Clinically improved elasticity, density and wrinkle appearance in 2 weeks. 30ml.

• Micro-Spicule Delivery System — Hydrolyzed Sponge, Avg 13μm — spicules are microscopic needle-like structures naturally found in sea sponges; when applied to skin and massaged, they create temporary microchannels in the stratum corneum (the outermost skin layer) without breaking the skin; these channels allow actives to bypass the barrier layer that normally limits topical absorption; clinical testing showed 132.8% higher absorption rate versus a spicule-free control formula; at an average of 13μm, the spicules are smaller than the average pore opening, ensuring they work without discomfort or irritation
• Retinol 0.2% + Retinal — Dual Retinoid Formula — retinol and retinal are both vitamin A derivatives but work at different speeds; retinol is converted by the skin into retinoic acid over two steps, making it gradual and well-tolerated; retinal (retinaldehyde) is one step closer to retinoic acid, so it works faster and more potently than retinol while remaining gentler than prescription tretinoin; combining both in one formula gives simultaneous slow-acting and faster-acting retinoid activity — clinically proven to improve skin elasticity, firmness and wrinkle appearance in 2 weeks
• Squalane — Retinol Stability + Barrier Support — squalane serves two roles in this formula; it stabilizes retinol (which degrades quickly when exposed to air and light) to ensure the active remains potent; and it reinforces skin barrier lipids that retinol can temporarily disrupt during adaptation — this is one reason retinol beginners often tolerate this formula better than pure retinol serums
• Madagascar Centella Asiatica + Madecassoside + Panthenol — the cushioning complex that makes 0.2% retinol approachable; centella provides full-spectrum cica calming (asiaticoside, asiatic acid, madecassic acid); madecassoside as an isolated active adds concentrated barrier repair on top; panthenol soothes and hydrates — together they minimize the redness, dryness and peeling that beginners typically experience during retinol adaptation
• Sea Buckthorn (Hippophae Rhamnoides) + Mung Bean Extract + Adenosine — sea buckthorn provides rare omega-7 (palmitoleic acid) and a dense antioxidant profile; mung bean extract detoxifies and provides a mild brightening effect; adenosine is Korean FDA-approved for wrinkle improvement and complements the retinoid anti-aging action; tocopheryl acetate (vitamin E) adds antioxidant stability to protect the retinol from oxidation

After toner, apply an appropriate amount to the full face avoiding the eye area and gently massage until absorbed. Follow with moisturizer. Start with 2–3 times per week and increase to daily use once skin has adapted. For targeted use, apply a small amount to concern areas only. Not recommended during pregnancy or breastfeeding. 30ml.
