It’s Skin Effector

The Power 10 Formula Effectors are concentrated single-active serums - each 30ml bottle is built around one main active ingredient at a high dose. Standard serums often blend multiple actives at moderate concentrations; Effectors go deep on one target per variant (GF for texture, VC for brightness, VB for calming, etc.). The 30ml format is intentional - small enough to finish in 4-6 weeks and reassess, which keeps actives fresh and lets you test variants systematically.

GF (growth factor) targets fine lines and uneven texture. VC (vitamin C) brightens hyperpigmentation and dullness. VB (vitamin B / niacinamide) reduces redness and calms reactive skin. All three come in 30ml and sit in the same serum step - after toner, before moisturizer. The two-letter code on the bottle tells you exactly which active you're buying, so reordering is straightforward once you know which one works for your skin.

Yes - Pio is the sebum-control variant in the range. It targets large pores and oily areas by regulating oil production rather than simply mattifying the surface. The Pio Pore Lupin version adds white lupin extract for additional pore-tightening. Both variants have a light, watery texture that sits well under moisturizer without adding heaviness. Oily skin types can use it AM and PM if needed.

VB (vitamin B / niacinamide) is generally the most tolerated variant for sensitive skin. Niacinamide at the concentrations used in Power 10 VB strengthens the skin barrier and reduces redness without the potential irritation of vitamin C or exfoliating actives. If your skin is very reactive, start with VB once daily before introducing other variants. The GF variant is also mild enough for most sensitive skin types.

Yes, stacking two Effectors is a common practice. GF plus VC is a popular combination for texture improvement alongside brightening. Apply the thinner, more watery formula first and let it absorb for about 30 seconds before adding the second. Avoid using L.I. (the exfoliant variant) alongside other active serums in the same routine - save L.I. for evenings on its own to reduce irritation risk.

Effectors are applied after toner and before any heavier serums, ampoules, or moisturizer. Their lightweight formula absorbs quickly, which means they don't create a barrier that blocks what comes after. If you use a dedicated essence, apply it before the Effector. In an AM routine, follow with SPF. In a PM routine, Effectors work well under a richer moisturizer or sleeping mask.

The Propolis Effector Luminous Fairy is a lighter-textured version of the original Propolis Effector. The 'Fairy' version has a thinner consistency that absorbs faster - better suited for warmer months, humid climates, or anyone who found the original Propolis formula too heavy for daily use. Both variants use propolis extract for antimicrobial and firming effects; the main difference is texture and finish, not active potency.

The V V Seragard is a dual-vitamin brightening Effector combining two forms of vitamin-related actives for more visible brightening than a single VC formula delivers. It's aimed at skin that has used standard vitamin C serums without achieving the brightness improvement expected, or for anyone who wants more coverage across the brightening spectrum. Like other Effectors, it comes in 30ml and fits into the same routine step.

The L.I. Effector contains exfoliating acids, so frequency depends on your skin tolerance. Most users start with 2-3 times per week in the evening, then adjust based on how skin responds. Avoid using L.I. on the same night as other actives like retinol or vitamin C. If you experience redness or flaking, reduce to once weekly. In AM routines, always follow any exfoliating step with SPF - the L.I. variant is best reserved for evenings.

Yes - the V-I Nutritionist is one of the richer variants in the Power 10 lineup and is a good fit for dry or dehydrated skin. It combines multiple vitamins in a slightly thicker base that provides more nourishment than standard Effectors. Dry skin types who found GF or VC too lightweight often find the V-I Nutritionist adds enough substance to skip a separate essence step. It still fits in the same serum position in a routine.

Yes - all It's SKIN Power 10 Formula Effectors on skinsli are sourced directly from the Korean market and shipped internationally. It's SKIN is a Korean cosmetics brand; the Effectors sold on skinsli carry original Korean-market packaging with ingredient lists in Korean and English. Batch codes are present on each bottle and match standard It's SKIN manufacturing codes.

At 4-5 drops per application once daily, a 30ml bottle lasts approximately 4-6 weeks. If you're applying twice daily, expect 2-3 weeks per bottle. The 30ml format is sized for a single trial period - long enough to judge whether a variant is producing visible results. Once you confirm a variant works for your skin, ordering two at a time covers about 2-3 months of daily use.
