Doctor K (株式会社ドクターケイ), a skincare brand born from over 20 years of clinical research into vitamin C, is launching a refill size for its popular exfoliating foam cleanser "ABC-G Peel Wash" on Wednesday, July 1, 2026.
The Long-Awaited Refill Is Here
Since its launch in July 2024, the ABC-G Peel Wash exfoliating foam cleanser has become a favorite among many users. Responding to customer feedback such as "I want to keep using it, so a refill would be great" and "It's a waste to throw away the bottle," a refill version is now arriving.
The ABC-G Peel Wash is a vitamin-colored exfoliating beauty foam cleanser designed for daily at-home skincare. Glycolic acid* gently softens clogged pores and unwanted dead skin cells, while amino acid-derived cleansing agents* wash away sebum and impurities.
Beyond cleansing, the formula features a combination of various vitamins including retinol*, niacinamide*, and vitamin C*, along with glutathione* for skin clarity*, human-identical ceramide* to condition skin cells and provide moisture and firmness, and マンダリンクリア* — a formulation that reflects Doctor K's long-standing commitment to vitamin research. The dense, smooth foam leaves skin healthy-looking, smooth, and refreshed.

Product Features
9 Science-Backed Formulations
① Glycolic Acid — Softens Clogged Pores and Dead Skin*
Glycolic acid*, used in aesthetic medicine as a peeling agent (skin-softening ingredient), is included at a concentration appropriate for skin sensitivity. Daily use helps soften and regulate clogged pores and buildup of dead skin cells, preventing pore congestion and skin thickening for a healthier complexion.
Glycolic acid* is a type of AHA (alpha hydroxy acid).
② カクテルビタミン® Formula — Boosts Skin Beauty Effects
A cocktail of 10 vitamins*, including Vitamin A, B, and C (retinol, niacinamide, vitamin C), each with proven skin benefits. The formula amplifies and complements the individual effects for a synergistic result. Retinol*, which is highly effective in regulating skin rhythm, further enhances exfoliating results.
③ Glutathione — Enhances Skin Clarity**
A tripeptide composed of glutamic acid, cysteine, and glycine, glutathione* naturally occurs in the human body. It provides moisture to skin that is prone to change due to age and external stress, helping maintain a healthy complexion. Combined with vitamin C derivatives (skin-conditioning agents), it helps refine skin texture and achieve a clear, luminous appearance.
④ Amino Acid-Derived Cleansing Agents — Soft and Moisturizing Finish*
Formulated with low-irritant amino acid-derived cleansing agents*, making it suitable even for sensitive skin. While retaining the moisture skin needs, it gently removes sebum, dirt, clogged pores, and dead skin cells.
⑤ Human-Identical Ceramide — Provides Moisture and Firmness*
Five types of human-identical ceramide* with a structure equivalent to the ceramide found in skin are included. The formula helps restore moisture and firmness to skin that has become dry* due to aging or external stress*.
⑥ マンダリンクリア — For a Clear, Even Complexion*
マンダリンクリア* adds firmness to the stratum corneum and imparts a deep, luminous transparency* to the skin. It helps achieve a clear, dullness*-free complexion.
⑦ Rich, Elastic Foam That Gently Wraps Skin
Despite its mild amino acid-derived cleansing agents*, the foam is surprisingly dense and bouncy. The generous lather envelops skin and washes it clean with a gentle touch. The foam's orange color comes from vitamin B12 (cyanocobalamin) in the formula.
⑧ Natural Essential Oil Fragrance
A refreshing citrus scent that energizes and uplifts. The crisp, clean aroma instantly brightens the mood.
⑨ 6-Free Formula
Free of mineral oils, synthetic colorants, synthetic fragrances, petroleum-based surfactants, parabens, and alcohol.
