SOME BY MI Yuja Niacin Brightening All-in-One Cleanser – 100ml | K-Beauty Brightening Face Wash

11% Yuja (Yuzu) Extract + Niacinamide + Dual Vitamin C | Deep Cleanse, Gentle Exfoliation & Brightening in One Step | Low pH | Non-Comedogenic | Vegan | All Skin Types

What It Is

The SOME BY MI Yuja Niacin Brightening All-in-One Cleanser is designed to both brighten and refresh skin using vitamin-rich ingredients. It combines Yuja Extract — known for its exceptionally high Vitamin C content — with Niacinamide to gently cleanse and support a more even skin tone.

The skin-friendly gel has a slightly acidic pH value and removes dirt, sebum, and even water-resistant makeup while gently exfoliating dead skin cells with the help of PHA and Succinic Acid.  The gel texture lathers into a rich, dense foam that effectively removes impurities without stripping the skin — leaving it soft, smooth, and healthy-looking. 

Key Benefits

• Brightens & evens skin tone — 11% Yuja (Yuzu) Extract is rich in Vitamin C at a concentration three times higher than lemon, fighting the process of glycation — the binding of collagen fibres — while delivering powerful antioxidant effects that prolong skin's youthful appearance. 
• Fades dark spots & acne marks — Niacinamide, Yuja Extract, and a touch of pure Vitamin C work together to brighten the skin's overall appearance, prevent inflammation, and fade hyperpigmentation such as acne scars and dark spots caused by sun exposure. 
• Gentle daily exfoliation — Gluconolactone (PHA) has larger molecules than AHA acids, making it suitable for sensitive skin — gently removing dead skin cells, evening microrelief, and lightening pigmentation without irritation. Amazon Succinic Acid complements this with mild antibacterial and sebum-mattifying properties.
• Dual Vitamin C delivery — 3-O-Ethyl Ascorbic Acid is a fat-soluble form of Vitamin C acting as a powerful antioxidant and anti-inflammatory agent that slows ageing and increases collagen synthesis, while Sodium Ascorbyl Phosphate is a stable form that whitens pigmentation, blocks inflammation, and stimulates collagen production.
• Barrier-supporting Niacinamide — Niacinamide strengthens the skin's natural protective barrier, stimulates collagen production, prevents the formation of pigmentation, and evens out skin tone. 
• Hydrates while it cleanses — enriched with moisturising Hyaluronic Acids to prevent skin from drying during cleansing and to maintain the moisture balance of the skin after cleansing. Triple Hyaluronic Acid (Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, and Sodium Hyaluronate Crosspolymer) ensures no post-cleanse tightness.
• Vitamin B complex boost — the formula is enriched with Biotin (B7), Pyridoxine (B6), Folic Acid (B9), Cyanocobalamin (B12), Thiamine HCl (B1), and Riboflavin (B2) — a full B-vitamin complex supporting skin cell renewal, metabolic function, and overall skin health. 

Formula & Clean Beauty Credentials

How to Use

Dispense a small amount of cleansing gel into wet palms and roll between palms until it has turned into a lather.

Why Seoulma Skincare Recommends It

A brightening cleanser is one of the most overlooked upgrades in a K-beauty routine — and the SOME BY MI Yuja Niacin is one of the most intelligently formulated versions available. Here's why Seoulma recommends it.

Most cleansers are purely functional — they clean skin and nothing more. This one treats skin simultaneously. The 11% Yuja Extract concentration is notably high for a rinse-off product: Yuzu is one of the most Vitamin C-dense citrus fruits in the world, and at this level it actively works on hyperpigmentation and dullness with every wash — not just as a fragrance note. Paired with dual stable Vitamin C forms (3-O-Ethyl Ascorbic Acid and Sodium Ascorbyl Phosphate) and Niacinamide, the brightening effect compounds over time with consistent use.

What elevates it further is the exfoliation approach. Rather than using a harsh AHA that can sensitise a skin barrier weakened by repeated cleansing, SOME BY MI chose Gluconolactone (PHA) and Succinic Acid — both effective at clearing dead skin cells and congestion, but gentle enough for daily use on sensitive and acne-prone skin without disrupting the pH balance the formula works hard to maintain.

The low-pH, non-comedogenic, alcohol-free formula means it functions as a genuine second cleanser in a double cleanse routine, or as a solo morning wash for those who prefer a lighter approach. And at 100ml, it's a practical, affordable entry point into the Yuja Niacin line — one of SOME BY MI's most beloved brightening ranges.
