Why You'll Love It

11-Vitamin Lip Care

ABC-G Lip Serum takes Doctor K's vitamin-focused skincare concept and adapts it specifically for the delicate lip area.

Its 11-vitamin complex includes:

• Retinyl Palmitate — vitamin A derivative
• Riboflavin Butyrate — Vitamin B2-related ingredient
• Niacinamide — Vitamin B3
• Calcium Pantothenate — Vitamin B5
• Pyridoxine Trihexyldecanoate — Vitamin B6 derivative
• Cyanocobalamin — Vitamin B12
• Tetrahexyldecyl Ascorbate — Vitamin C derivative
• Magnesium Ascorbyl Phosphate — Vitamin C derivative
• Tocopherol — Vitamin E
• Biotin — Vitamin H
• Glucosyl Hesperidin — Vitamin P-related ingredient

These ingredients are included as antioxidant components for the product formula.

Retinyl Palmitate + Two Vitamin C Derivatives

The serum contains Retinyl Palmitate, a vitamin A derivative. Retinyl Palmitate should not be confused with pure retinol.

It is paired with two Vitamin C derivatives — Tetrahexyldecyl Ascorbate and Magnesium Ascorbyl Phosphate — as part of Doctor K's multi-vitamin lip care formula.

Five Human-Type Ceramides

To support the delicate lip area, ABC-G Lip Serum contains five human-type Ceramides:

• Ceramide AG
• Ceramide AP
• Ceramide EOP
• Ceramide NG
• Ceramide NP

These moisturising ingredients help condition the stratum corneum of the lips and support a smoother, more comfortably hydrated feel.

Hyaluronic Acid + Peptide

The formula combines two forms of Hyaluronic Acid:

Sodium Hyaluronate
Hydrolysed Hyaluronic Acid

Both are moisturising ingredients that help keep lips feeling hydrated and supple.

Palmitoyl Tripeptide-1 is also included as a moisturising peptide, complementing the formula's intensive moisture care.

Glutathione

Glutathione is included as a moisturising ingredient, supporting lips that look fresh and translucent through hydration.

Rather than making a pigmentation claim, the formula's “translucency” positioning refers to the appearance created by well-moisturised lips.

Helps Prevent Lip Roughness

Dipotassium Glycyrrhizinate is included as a skin-conditioning ingredient to help maintain lips in a healthy condition and protect against roughness.

Combined with the serum's moisturising ingredients, it makes the formula particularly suitable for lips prone to dryness and uneven texture.

Smooth, High-Adhesion Moisture

Doctor K uses a smooth, high-adhesion formula designed to combine easy application with lasting protection against dryness.

The serum glides smoothly over the lips, then adheres closely to help maintain a moisturised, supple feel without requiring a thick or difficult-to-spread texture.

Three Ways to Use It

As a Lip Primer

Apply before lipstick or other lip makeup to smooth and moisturise the lips.

As a Lip Gloss

Wear it alone as a moisturising lip serum and gloss for a smooth, hydrated finish.

As an Overnight Lip Treatment

Apply before bed to protect lips from dryness while you sleep. An additional layer can be applied to particularly dry or rough areas.

Texture & Scent

Texture: Smooth, moisturising and high-adhesion
Finish: Supple, smooth and hydrated
Scent: Relaxing Orange

The serum's natural orange colour comes from Cyanocobalamin (Vitamin B12) contained in the formula rather than added colour for decorative effect.
