Why You'll Love It
A Gentle Approach to Retinoid Skincare
ABC-G Repair Serum is centred around Retinyl Palmitate, a vitamin A derivative selected by Doctor K for its stability and relatively gentle action.
According to the product formulation concept, the derivative is converted within the skin — specified by the brand as up to the stratum corneum — to provide its skincare benefits.
Retinyl Palmitate is a vitamin A derivative and should not be confused with pure retinol.
Retinyl Palmitate + Niacinamide + Vitamin C
Rather than relying on a single hero ingredient, Doctor K combines Retinyl Palmitate with:
Niacinamide — included as a moisturising ingredient.
Magnesium Ascorbyl Phosphate — a Vitamin C derivative included as a moisturising ingredient.
This multi-ingredient approach is designed to support smooth, healthy-looking skin while providing daily moisture care.
Glutathione for a Translucent-Looking Glow
The formula also contains Glutathione as a moisturising ingredient.
Together with Niacinamide and Vitamin C, it supports hydrated skin with a fresh, translucent-looking appearance.
Here, “translucency” refers specifically to the appearance of skin through hydration.
Glycolic Acid for Smoother Texture
Glycolic Acid is included as a moisturising ingredient that helps soften the keratin layer.
This complements the serum's retinoid-focused formula, helping skin feel smoother and more refined — the inspiration behind Doctor K's description of an “egg-smooth” complexion.
Human-Type Ceramides
ABC-G Repair Serum contains two human-type ceramides:
- Ceramide AP
- Ceramide NP
Both are included as moisturising ingredients and help provide moisture to the stratum corneum, supporting a plump and firm-looking complexion.
Mandarin Clear®
Mandarin Clear®, Doctor K's name for Mandarin Orange Peel Extract, is included as a moisturising ingredient.
It complements the vitamin, ceramide and glycolic acid combination within the serum's multi-ingredient approach to smooth, hydrated-looking skin.

How to Use
Before first use, Doctor K recommends performing a patch test:
- Apply a thin layer approximately the size of a 10-yen coin to the inner arm.
- Allow it to dry naturally.
- Check that no skin abnormality develops before using the product on your face.
For facial use:
- After applying lotion/toner and preparing the skin, spread the serum gently over the entire face.
- It can also be used around the outer corners and under-eye area, as well as the neck, where age-related concerns are noticeable.
- If your skin is sensitive, begin with a small amount and gradually allow your skin to become accustomed to the Retinyl Palmitate formula.
- Once your skin has adjusted, use approximately 2 pumps per application.
The serum can also be used in the morning, but Doctor K specifically recommends always applying sunscreen afterwards.
