Take the skin testFirst acne-drying powder in Korea with pantothenic acid. Instantly soothes and flattens new acne, micro breakouts, and red bumps by controlling excess oil and reducing impurity buildup.
No.1 Pantothenic B5 Active Drying Powder is a lightweight treatments from Numbuzin, a brand based in Korean. Its job is UV protection, with the rest of the formula working on oil control and soothing. The ingredient list runs to 17 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order.
It is a mineral sunscreen, filtering with Zinc Oxide. Between them those filters cover UVB, UVA II and UVA I, so the formula is broad-spectrum in the meaningful sense: it reaches past 340 nm, where the ageing wavelengths sit. Every filter in the formula is photostable, so its protection does not fall away over the first hour in the sun — reapplication is still about sweat, water and rubbing rather than degradation.
Oil control: High. Ingredients that moderate sebum or absorb shine, and here that comes from Silica, Zinc Oxide, Niacinamide and Maltodextrin.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Asiaticoside, Madecassoside and Zinc Oxide.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Pantothenic Acid and Madecassoside.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Dipotassium Glycyrrhizate and Pueraria Lobata Root Extract.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working. It carries UV filters, so it belongs in your morning routine.

Possibly. It filters with mineral UV filters, which sit on the surface and can leave a visible cast on deeper skin tones, especially at high SPF.
It contains none of the filters named in the Hawaii and Key West reef legislation (oxybenzone and octinoxate). "Reef safe" is not a regulated term, so treat that as a fact about the filter list rather than a certification.
