IT'S SKIN: Real Results, Real Beauty Your Skincare Journey Starts Here!

There is a small group of Korean skincare brands that built their name on one formula and earned it honestly, and IT'S SKIN is one of them. Power 10 on the ingredient list, PRESTIGE Ginseng on the box, and a product range that manages to span clinical actives and gentle daily care without losing the plot.

This piece is a proper introduction to IT'S SKIN: where the brand comes from, what the Power 10 system actually does, which lines earn their place in a real routine, and who should probably look elsewhere. Every IT'S SKIN reference we mention is in stock at Kool Seoul, sourced from Seoul and shipped worldwide via DHL Express — free shipping on orders over $150.

Where IT'S SKIN actually comes from

IT'S SKIN is a Seoul-based Korean skincare brand that launched in the mid-2000s during the first big wave of K-beauty going global. Unlike brands that staked everything on novelty ingredients, IT'S SKIN built its reputation on the Power 10 Formula system — a set of small, numbered, single-ingredient serums that gave customers a way to target their skin concerns without buying a complete new range every time one ingredient became fashionable. That system is still its most recognised export.

The brand is manufactured in South Korea, and every product we stock at Kool Seoul carries Korean-language packaging, Korean production codes, and Korean barcodes. That matters because IT'S SKIN is popular enough to attract grey-market repacking — the kind of thing that swaps genuine Korean-market bottles for repackaged stock with a sticker over the origin label. We do not do that. If a batch does not clear our sourcing check in Seoul, it does not ship.

IT'S SKIN sits in a space between a clinical Korean brand and an affordable everyday shelf. Some lines — PRESTIGE Ginseng, the newer Glutathione Shot — lean premium. Others — the Snail Collagen Active trio, the Power 10 masks, the single-item cleansers — are designed for everyday, budget-conscious K-beauty shopping. That breadth is deliberate, and it makes IT'S SKIN one of the more practical all-in-one-brand routines you can build without switching houses.

The Power 10 Formula system — IT'S SKIN's signature

It's Skin Power 10 Licorice Julen Jelly Mask Packa licorice jelly mask from the brand's hero Power 10 line$5Shop now →

The Power 10 Formula concept is straightforward: pick an active ingredient, concentrate it at serum-grade levels, and sell it in a small bottle labelled by function. Vitamin C for brightening. Hyaluronic acid for hydration. Niacinamide for pore refinement. Licorice root for uneven tone. The customer chooses the one — or two — that fits their current concern, layers it under a moisturizer, and moves on. No guesswork about "complete systems" sold as a bundle.

The Power 10 range has since expanded into sun creams and mask packs. The Power 10 Licorice Julen Jelly Mask Pack brings the licorice brightening concept into a single-use format — one of the most affordable entry points to the Power 10 system and a good way to trial the ingredient before committing to a serum. The Power 10 Licorice Julen PAdepree Sun Cream folds licorice root into a Korean-style daily SPF50+ PA++++ — the kind of protection the Korean market has been doing well for longer than the rest of the world noticed.

The Power 10 VC Tone Up Sun Cream takes the same format and replaces licorice with vitamin C, giving skin a soft luminance from the first application. Korean sunscreens are formulated and tested differently to European and American SPFs — lighter textures, more elegant wear, and reformulated more frequently — and the Power 10 VC is a good example of why this category has become its own genre.

The Snail Collagen Active line — the everyday workhorse

Snail filtrate has been part of the Korean skincare vocabulary for longer than most international customers realise. The Snail Collagen Active line from IT'S SKIN is not about a trend — it is a straightforward, three-step routine built on snail secretion filtrate and marine collagen: toner, emulsion, cream. Each step prepares the skin for the next, and together they build the kind of baseline hydration and skin-feel improvement that makes everything else in the routine work better.

The Snail Collagen Active Toner is a watery first layer after cleansing — priming, softening, and starting the hydration stack. Follow it with the Snail Collagen Active Emulsion, a milky mid-step that bridges the gap between toner and cream. Finish with the Snail Collagen Active Cream to lock everything in. The three together at $77 is a full Korean-style moisturizing routine at a price point that undercuts most European equivalents by a significant margin.

The Blue Snail variant — the Blue Snail Cream and Blue Snail Serum — reformulates the snail filtrate concept with a calming, slightly soothing bias. It is the version we recommend to customers coming off a period of over-exfoliation or dealing with post-breakout redness.

Glutathione Shot B3 — IT'S SKIN's brightening duo

It's Skin Glutathione Shot B3 Serum · 30mla glutathione and niacinamide serum for even, luminous skin$34Shop now →

The Glutathione Shot B3 line is IT'S SKIN's answer to the growing international interest in complexion-evening through antioxidant-forward formulas. Glutathione is a naturally occurring antioxidant present in skin cells; at the concentrations used in Korean cosmetic formulas, it is widely paired with niacinamide (B3) for a dual approach to uneven tone — glutathione as the antioxidant net, niacinamide as the barrier support and pigmentation suppressor.

The Glutathione Shot B3 Serum is the treatment step — 30ml of a concentrated, quick-absorbing serum that layers cleanly under the Glutathione Shot B3 Toner, which functions as both a hydrating first step and a mild brightening prep. Together they make a two-product brightening sub-routine that sits inside any existing stack without adding significant time or weight.

We flag an honest caveat here: glutathione in topical cosmetics is an active area of discussion between formulators, and the research on transdermal penetration of glutathione specifically (as opposed to related antioxidants) is still developing. What we can say from experience with customers is that the Glutathione Shot B3 line reads lighter and less irritating than many brightening serums that rely on high-percentage vitamin C, which can sting sensitised skin.

PRESTIGE and the premium side of IT'S SKIN

It's Skin Prestige Edatpair Glow Firming Sleeping Mask · 80mla firming overnight mask from IT'S SKIN's premium PRESTIGE range$54Shop now →

The PRESTIGE line is where IT'S SKIN moves away from accessible-everyday and toward premium-occasion. The hero ingredient family is Edatpair — a portmanteau of "elastin, adenovirus (purified plant cell), and peptide repair" — built around a cocktail of skin-firming and recovery actives. It is the range IT'S SKIN reaches for when it wants to sit next to a department-store brand rather than next to a convenience-store shelf.

The PRESTIGE Edatpair Glow Firming Sleeping Mask is the centrepiece: an overnight mask at 80ml that delivers firming, radiance, and hydration while you sleep. At $54 it is the priciest thing in the IT'S SKIN range at Kool Seoul, and it earns that position because the texture — rich but non-greasy, absorbs without transfer onto the pillow — is genuinely different from anything in the more affordable IT'S SKIN lines.

The Prestige Snail masks sit at a much friendlier price point. The Prestige Snail Hyaluron Mask layers snail filtrate with hyaluronic acid in a sheet format — a fifteen-minute treatment that reads more restorative than the typical single-HA sheet mask. The Prestige Snail Niacin Mask replaces the HA with niacinamide for a brightening-and-repair variant. Both are at $6 per sheet — the entry door to the PRESTIGE range without the commitment of a full cream.

Suncare and specialty — the rest of the IT'S SKIN range

It's Skin Good Day Mate Daily Sun · SPF50+ PA++++a lightweight Korean daily sunscreen for year-round wear$30Shop now →

Beyond the Power 10, Snail Collagen, and Glutathione lines, IT'S SKIN's catalogue has expanded into a set of specialist references that are worth knowing. The Good Day Mate Daily Sun SPF50+ PA++++ is the brand's general-use daily sunscreen — light, non-chalky, and formulated to sit without pilling under makeup. Korean SPF50+ PA++++ means maximum phototype protection across both UV-A and UV-B wavelengths by Korean testing standards; use it as an everyday urban shield and reach for a higher physical-filter SPF if you are at the beach for extended periods.

The All About Glow Tone Up Cream bridges moisturizer and base makeup — a cream-format tone corrector that adds soft luminance without covering. Paired with the All About Glow Cover Cream SPF50+ PA++++, which adds a light coverage layer and built-in sun protection, the two form a stripped-down Korean "skin prep" — something between a primer, a moisturizer, and a light base — that is popular for the warmer months or low-coverage summer looks.

For cleansing, the Minofull Bubble Cleanser is a foaming water-based cleanser built for a mild, everyday second-cleanse. The Power 10 Formula Cleansing Foam Soothing brings the Power 10 active logic to cleansing — a soothing foam that lifts without stripping. On the exfoliation side, the Apple Jam Scrub Foam combines a gentle physical scrub with a foam cleanser, a once-or-twice-a-week step for skin that feels rough or congested rather than sensitive.

How to build an IT'S SKIN routine (AM + PM)

A simple IT'S SKIN morning: the Power 10 Cleansing Foam Soothing or a light rinse, the Glutathione Shot B3 Toner, the Glutathione Shot B3 Serum if you are targeting uneven tone, the All About Glow Tone Up Cream or the Snail Collagen Active Cream, and finish with the Good Day Mate Daily Sun or one of the Power 10 sun creams. Four to five steps, under ten minutes.

A simple IT'S SKIN evening: Minofull Bubble Cleanser or Apple Jam Scrub Foam (on exfoliation nights), the Snail Collagen Active Toner, the Snail Collagen Active Emulsion, and the Snail Collagen Active Cream. Once or twice a week, swap the emulsion step for the Prestige Snail Hyaluron or Niacin Mask. On nights you need a firming boost, use the PRESTIGE Edatpair Sleeping Mask instead of the cream and leave the rest of the routine beneath it.

Who IT'S SKIN is really for — and who it isn't

IT'S SKIN is a great fit if you want a brand that can cover most of your routine without switching houses, if you like the idea of picking a targeted active (licorice, vitamin C, glutathione, niacinamide) rather than a complete "system", and if you want Korean skincare at a price point that does not require a premium budget for every step. It also suits people building their first proper K-beauty routine who want clear ingredient logic rather than poetic brand narratives.

IT'S SKIN is not the right brand if you want a single ultra-clean, short-INCI, organic-first range — this is a mainstream Korean brand that uses conventional cosmetic chemistry alongside its active ingredients. It is also not the place to look if you want very high-percentage clinical actives like 2% retinol or pharmaceutical-grade vitamin C. And if you find multi-line brands overwhelming, the breadth of IT'S SKIN's catalogue — Power 10, Snail Collagen, Blue Snail, Glutathione, PRESTIGE, All About Glow, Good Day Mate — can feel like too much choice. The short answer to that: start with Snail Collagen Active toner, emulsion, cream. Everything else is optional.

What to expect in the first few weeks

The Snail Collagen Active routine reads quickly — within a week or two most people notice skin feels softer and looks less dull at the end of the day. The Glutathione Shot B3 takes longer; brightening actives work over weeks, not days, and the visible change tends to be subtle at first (even tone rather than dramatic lightening). The Power 10 masks give the most immediate feedback — the licorice jelly mask in particular gives a visible glow within thirty minutes that makes it useful before an event or a video call.

What you should not expect: a complete complexion transformation in under a month. IT'S SKIN is a consistent, long-term skincare brand. It rewards daily use more than occasional experimentation, and the customers who get the most from it are the ones who build a simple foundation — toner, serum, moisturizer, SPF — and stick with it through a full skin cycle rather than switching brands every three weeks.

IT'S SKIN — frequently asked questions

Is IT'S SKIN a legitimate Korean brand?

Yes. IT'S SKIN is a South Korean cosmetics brand manufactured in Korea, with a long retail presence in Korean convenience stores, major Korean beauty chains, and international K-beauty export channels. Every product Kool Seoul ships carries Korean-market packaging with Korean production codes — not grey-market or repackaged stock.

What is the Power 10 Formula?

Power 10 Formula is IT'S SKIN's signature line of concentrated serum-ampoules, each built around a single active ingredient. The name refers to a "10 times concentrated" actives claim. The range includes formulas built around licorice root (brightening), vitamin C (radiance and antioxidant), niacinamide (pore and barrier), and hyaluronic acid (hydration), among others. The same Power 10 logic has extended into mask packs and sun creams.

What is the PRESTIGE Ginseng range?

PRESTIGE is IT'S SKIN's premium sub-brand. The Edatpair family within PRESTIGE uses a blend of elastin, purified plant-cell extract, and peptides for a firming and radiance focus. The Prestige Snail masks use snail filtrate alongside either hyaluronic acid (Hyaluron) or niacinamide (Niacin) for accessible, single-use treatment options. Ginseng is one of the older hero ingredients associated with the PRESTIGE range in Korea, where red ginseng in skincare has a long established history as a luxury ingredient.

Which IT'S SKIN product is best for brightening?

The Glutathione Shot B3 Serum and Toner are the most targeted brightening duo in the current IT'S SKIN range. For a budget-friendly first trial, the Power 10 Licorice Julen Jelly Mask Pack is the lowest-commitment entry point to IT'S SKIN's brightening logic. The Power 10 VC Tone Up Sun Cream adds daily vitamin C protection without a dedicated serum step.

Is IT'S SKIN good for sensitive skin?

The Snail Collagen Active trio and the Blue Snail lines are the most barrier-focused and generally the most tolerated by sensitive skin types in the IT'S SKIN range. The Glutathione Shot B3 reads lighter and less irritating than high-percentage vitamin C serums. The Power 10 actives are more concentrated, so if your skin is reactive, introduce them one at a time and patch-test on the inner arm for 48 hours first. For very sensitive or reactive skin, consult a dermatologist before adding any new active to your routine.

How is IT'S SKIN different from COSRX or Innisfree?

All three are mainstream South Korean skincare brands with broad international distribution, but they sit in different positions. COSRX is arguably the most clinical of the three — minimal formulas, very few steps, heavy focus on acids (BHA, PHA) and snail mucin. Innisfree leans on Jeju Island botanicals — green tea, lava seawater, volcanic clay — with a nature-story that runs through everything. IT'S SKIN sits in a third place: ingredient-logic through the Power 10 system, affordable multi-step routines through the Snail Collagen Active line, and a premium tier through PRESTIGE. If you like clean-formula minimalism, COSRX. If you want a botanical-first brand with a strong island story, Innisfree. If you want a broad toolkit of actives in accessible, layerable textures, IT'S SKIN.

Does IT'S SKIN ship worldwide?

IT'S SKIN products at Kool Seoul ship from Seoul worldwide via DHL Express with full end-to-end tracking. Transit to the US, Europe, and Australia is typically three to six business days from dispatch. Shipping is free on orders over $150. Kool Seoul sources all IT'S SKIN stock through Korea's own distribution network, so you receive Korean-market inventory — not repackaged or grey-market product.

What is the Hyaluronic Acid Moisture Serum from IT'S SKIN?

The Hyaluronic Acid Moisture range is IT'S SKIN's dedicated hydration line, built on multi-weight hyaluronic acid molecules designed to sit at different skin depths. Lighter, low-molecular-weight HA penetrates closer to the surface and draws water in; heavier HA forms a film at the surface to slow transepidermal water loss. The range is designed for dehydrated skin — specifically the kind that feels tight within an hour of cleansing regardless of weather — and pairs well with either the Snail Collagen Active cream as a sealing step or with the PRESTIGE Sleeping Mask on drier nights.
