I.st

I.st is a treatment-led skincare brand rather than a basics-only line. The products we stock cluster around brightening and repair: a peeling gel for gentle exfoliation, collagen toner pads, a couple of targeted creams, and a hydrogel mask. The thread running through the range is improving tone and texture, so it suits someone whose main concerns are dullness, uneven surface, or skin that needs recovery support.

The Brightening Peeling Gel comes in a 120ml size, and there is a newer reformulated version in the lineup alongside the original. A peeling gel is a gentle, roll-off exfoliant: you massage it over damp skin and it lifts away dead surface cells without the grit of a scrub. Used once or twice a week, it clears the way for the rest of your routine to absorb better and helps skin look brighter. It is the prep step that makes the creams and pads work harder.

The Collagen VC Tangle Pad comes as a 70-sheet pad pack, pairing collagen with a vitamin C theme for brightening and a plumped feel. Toner pads are a convenient way to deliver an essence step: you wipe one over clean skin to tone, lightly exfoliate, and lay down active ingredients in one move. A 70-count tub lasts a long stretch of daily use, which makes it the everyday workhorse in the I.st range, sitting between cleansing and your creams.

The Dermo PDRN Rejuvenation 100 Cream is a 50ml treatment cream built around PDRN, an ingredient popular in Korean skincare for its repair and rejuvenation associations. This is the targeted step for anyone focused on skin recovery, resilience, and a smoother look over time. As a richer cream it sits later in the routine, sealing in the lighter pad and serum steps and giving your skin a treatment-grade finish at the end of the day.

The Didier Hempstem Cream is a 50ml moisturiser, the second cream in the range and a more general hydration and comfort option next to the PDRN treatment cream. If the PDRN cream is your concentrated repair step, the hempstem cream is the everyday moisturiser that keeps skin soft and balanced. Having both lets you choose a lighter daily cream and a richer treatment cream depending on the night and what your skin needs.

The Repair Hydrogel Mask Pack is a 5-sheet set of hydrogel masks, the intensive weekly step in the I.st lineup. Hydrogel masks hug the face more closely than paper sheets and hold their essence well, so they are good for a concentrated burst of repair and hydration. Use one when skin feels stressed or after exfoliating, then follow with a cream. Five sheets makes it an occasional treat rather than a daily product.

A sensible I.st routine runs as cleanse, exfoliate, tone, treat, seal. Use the peeling gel once or twice a week for exfoliation, then on daily nights wipe a collagen toner pad over clean skin, apply your treatment, and seal with a cream. Reserve the PDRN cream for repair-focused nights and the hempstem cream for lighter ones, and slot a hydrogel mask in once a week. The key is not to stack the peeling gel and a strong mask on the same evening so your skin is not overworked.

The brightening and repair focus suits skin that looks dull, uneven, or tired, and the range gives you both gentle exfoliation and rich treatment creams. If your skin is sensitive, go slow with the peeling gel and patch the PDRN cream before nightly use. Drier skin will lean on the hempstem cream and hydrogel mask for comfort, while anyone chasing tone will get the most from the peeling gel and collagen pads. Introduce one new step at a time so you can tell what is working.

Every I.st product we list at skinsli is sourced as authentic stock and shipped from our own inventory, so you receive the genuine Korean formula in the correct size rather than a grey-market repackage. Ingredient-led skincare like the PDRN cream and collagen pads is exactly where authenticity matters, since the actives are the reason to buy. Items arrive sealed and as the brand intended.
