ISOI Skin Concern Pad Duo (PDRN Glow Toning Pad / Fresh Cica Cool Calming Pad)

Ingredient analysis and how the ad lines read

Read on 2026-09-17

What is this product?

A two-SKU pad set from ISOI sold as one retail listing, pairing a brightening pad with a soothing pad that share a hyaluronic backbone but differ in active axis and sheet count. The PDRN Glow Toning Pad (80 sheets) carries niacinamide fifth on a 31-item list and holds a Korean whitening functional-cosmetic notification, with sodium DNA declared at 100ppb as the listed counterpart to the brand's rose PDRN wording. The Fresh Cica Cool Calming Pad (60 sheets) runs a 39-item list built on five centella-derived entries with declared ppb figures, glacial water second, and a trio of plant extracts the brand names as its cooling complex; it carries no functional notification. Neither list names a fragrance ingredient, each carries one essential oil, and both pads are printed for wipe-off or leave-on pack use. Brand-cited in-vivo tests exist for both (21 subjects for efficacy, 31 for irritation) but no report is linked and no grade is printed.

What makes it different?

One catalogue record holds two genuinely different formulations rather than a size or shade variant: the whitening-notified niacinamide pad and the unnotified centella cooling pad share only 21 of their 31 and 39 listed items, so the pairing is a concern-matched duo rather than a line extension. The soothing pad also prints five centella actives with individual ppb figures, an unusually itemised disclosure for a pad, while the toning pad's brand-facing PDRN wording resolves to a listed sodium DNA entry at the same declared figure.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 3 with no dictionary entry, left in Korean.

Key ingredient

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: 센티드제라늄꽃오일, 유칼립투스잎오일
