Sam'u

SAM'U is a Korean skincare brand focused on sensitive, barrier-friendly care. The range we stock runs across two main lines: the pH Sensitive series of low-pH toner, cream, mask, sunscreen, and sunstick, and the Panthenol line of soothing serums, a peel toner, a healing mask, and a jelly wash, plus the Galactopore pore serum. Panthenol and a gentle pH are the threads that tie it together, so the brand suits reactive, easily irritated skin that does better with calm formulas than strong actives.

Buying guide

SAM'U: a buying guide to the pH-sensitive and panthenol range

SAM'U is a Korean brand for sensitive, easily irritated skin. We carry 25+ products from the line, and most of them belong to one of two families: the pH Sensitive series, which keeps formulas at a low, skin-friendly pH, and the Panthenol line, which leans on panthenol to calm and repair. Around those sit a pore serum and two sun products. This guide explains what each part does and how to build a gentle routine from it.

Who SAM'U is for

SAM'U is built for reactive skin that flushes, stings, or flakes when pushed too hard. Rather than chasing strong actives, the brand keeps its formulas at a gentle pH and reaches for panthenol, a well-known soothing and barrier-supporting ingredient. If your skin reacts to most products, or you are recovering from over-exfoliation, this is the kind of low-drama range that lets the barrier settle.

The pH Sensitive line

The pH Sensitive series is the brand's backbone, and we stock most of it: the PH Sensitive Toner (130ml), the PH-sensitive Cream (60ml), the PH Sensitive Mask Pack (150ml), and PH-sensitive Sunscreen (50ml). Keeping cleansing and care close to the skin's natural acidity helps protect the barrier instead of stripping it. Used together, these give you a full low-pH routine from toner through moisturiser and sun protection, which is useful if your skin is sensitised and you want every step to stay gentle.

The Panthenol line

The Panthenol products are the soothing core. The This Panthenol To To Serum (50ml) and the This Panthenol Healing Mask Pack (25ml) deliver concentrated panthenol to calm redness and support repair, while the Bon Panthenol Peel Toner (180ml) is a gentler take on a peel toner and the Bon Panthenol Jelly Wash (100ml) is a low-stress cleanser. Panthenol (provitamin B5) is valued for reducing irritation and helping skin hold water, so this line is where you turn when skin feels tight or angry.

Galactopore pore serum

The Galactopore Serum (40ml) is the brand's answer to enlarged pores and uneven texture. Galactomyces-style ferment serums are a long-running Korean category aimed at refining the look of pores and brightening tone while staying mild enough for sensitive skin. Use it after toner and before your cream. It pairs naturally with the pH Sensitive and Panthenol products, since all three keep to the same gentle approach rather than fighting each other.

Sun care: sunscreen and sunstick

Two sun products round out the range. The PH-sensitive Sunscreen (50ml) is a daily facial SPF formulated to match the rest of the sensitive line, and the Sensitive Pocket Sunstick (10g) is a compact stick for reapplying over the day or on the go. A stick is handy for topping up sun protection over makeup or out and about, where a cream is awkward. For sensitive skin, a sunscreen that shares the brand's gentle formulation philosophy is an easy way to keep the last step from causing a reaction.

Cleansing and the first step

The Bon Panthenol Jelly Wash (100ml) is the cleansing option in the range. A jelly or gel wash tends to be lower-stress than a foaming cleanser for sensitive skin, lifting the day off without leaving the face squeaky and tight. Starting your routine with a gentle cleanse matters most for reactive skin, because an aggressive first step undoes whatever the soothing products do later. Follow it with the pH Sensitive Toner to bring the skin back to its preferred acidity.

Building a routine from the range

A full SAM'U day looks like this: cleanse with the Bon Panthenol Jelly Wash, balance with the PH Sensitive Toner, treat with the Panthenol serum or Galactopore serum depending on whether your priority is calming or pores, seal with the PH-sensitive Cream, and finish with the PH-sensitive Sunscreen in the morning. Add a mask, either the PH Sensitive or the Panthenol Healing mask, once or twice a week. Because everything is built to be gentle, you can layer the lines without the usual worry about clashing actives.

Choosing the right products and sizes

Pick by your main concern. If redness and irritation lead, start with the Panthenol serum and mask. If you want a complete gentle base, the pH Sensitive toner, cream, and sunscreen cover the essentials. The 180ml Bon Panthenol Peel Toner is a generous everyday size, while the 25ml Healing Mask is a smaller targeted treatment. The 10g sunstick is the travel and reapply companion to the full-size sunscreen rather than a replacement for it.

Authenticity and Korean sourcing

Every SAM'U product we list is sourced from Korea and sold as genuine brand stock. For sensitive-skin care this matters more than usual: a counterfeit or mishandled formula can shift its pH or active level and trigger exactly the irritation the range is meant to prevent. If your skin is reactive, start with one product, patch test it on a small area for a few days, and add the rest of the routine once you know it sits well.
