What is this product?

Round Lab's Birch Moisture Soothing Gel is a 150ml oil-free hydrating gel sold on the after-sun shelf. The panel is 32 items and carries none of the usual irritant classes: no fragrance entry, no essential oil, no denatured alcohol, no plant oil, no silicone and no UV filter, with preservation handled by glycols and hydroxyacetophenone. Birch sap is disclosed at 10,000ppm in position 6, which is one percent and is one of the few numeric disclosures in this shelf, but the hydration is actually carried by butylene glycol, dipropylene glycol and glycerin at positions 2 through 4 plus glyceryl glucoside and two hyaluronic forms at 7 through 9. Twelve plant extracts run from position 10 to 26, including neem leaf and flower, holy basil and turmeric root, which is a wider botanical block than the format usually carries. There is no cooling agent in the list, so the cooling is evaporative and stops when the layer dries. The statutory filing row reads 해당사항 없음, meaning no functional-cosmetic filing, which also places the ascorbic acid at position 29 well below any regulated level. Nothing occlusive is present, so dry skin needs a cream over it. The ingredient panel here comes from a retail disclosure record rather than from a brand-published page.

What makes it different?

Three things separate it from the gels beside it. First, it carries a real number: birch sap at 10,000ppm printed inside the statutory panel, which is rarer on this shelf than the marketing suggests and lets a reader check the claim instead of trusting it. Second, the panel is genuinely oil-free rather than low-oil, with not one plant oil, butter, wax or silicone in 32 items and only three light esters, which is what makes a 150ml format usable across a whole body without residue. Third, and least flattering, the cooling the shelf and the listing tag both trade on has no agent behind it: no menthol, no menthyl lactate, no camphor, no alcohol. The cool is the water leaving, which is honest physics and a shorter effect than the word implies.

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.

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: 에틸헥실팔미테이트, 세틸에틸헥사노에이트, 폴리글리세릴-10미리스테이트, 카프릴릭/카프릭트라이글리세라이드
