Fit by skin type
General, ingredient-based — not your personalized match.
See how this fits your skin
Take the skin test and I'll show you how suitable this product is for you.
Take the skin testLightweight, daily serum enriched with pantothenic acid for excess oil control, preventing pores from clogging and causing breakouts and acne. Absorbs quickly within 7 seconds and offers deep hydration for clear, soothed, and breakout-free skin.
No.1 Pantothenic B5 Active Soothing Serum is a lightweight serum from Numbuzin, a brand based in Korean. The formula is built mainly around hydration and soothing. The ingredient list runs to 55 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. Hydration is handled by Butylene Glycol, Glycerin and Panthenol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Panthenol and Propanediol.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Allantoin, Centella Asiatica Extract and Beta-glucan.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Alpha-arbutin, Glycyrrhiza Uralensis Root Extract and Dipotassium Glycyrrhizate.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Panthenol, Hydrogenated Lecithin and Pantothenic Acid.
On richness alone it suits Balanced, Combination (oily) and Oily 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 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.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
