Why You'll Love It
Three Forms of Vitamin C
C Concentrate Oil Serum features three Vitamin C derivatives:
- Tetrahexyldecyl Ascorbate
- Trisodium Ascorbyl Palmitate Phosphate
- Magnesium Ascorbyl Phosphate
They form the core of Doctor K's concentrated vitamin oil approach, complemented by vitamins A, B and E.
A Multi-Vitamin Oil Serum
Beyond Vitamin C, the formula contains a broad range of vitamin ingredients:
Vitamin A — Retinyl Palmitate
Vitamin B1 — Thiamine HCl
Vitamin B3 — Niacinamide
Vitamin B5 — Calcium Pantothenate
Vitamin B6 — Pyridoxine HCl
Vitamin B12 — Cyanocobalamin
Vitamin B2 — Riboflavin
Vitamin E — Tocopherol
Retinyl Palmitate is a vitamin A derivative and should not be confused with pure retinol.
Caffeine + Glutathione
Doctor K also incorporates Caffeine and Glutathione into the vitamin-rich formula.
These ingredients complement the serum's moisture and conditioning approach, supporting skin that looks fresh, smooth and healthy.
The product does not make a medicated brightening claim, so Glutathione should be understood here within the serum's cosmetic skincare positioning rather than as a treatment for pigmentation.
Care for Skin Affected by External Stress
Doctor K developed the serum around what it describes as a cycle of skin roughness associated with external stressors such as pollen and dryness.
When skin feels unstable due to environmental dryness, concerns such as visible pores, dullness, excess shine and uneven texture can become more noticeable.
The oil-rich formula helps maintain moisture and skin condition while helping prevent roughness.
Botanical Oils Without a Heavy Feel
The formula begins with Squalane and includes Jojoba Seed Oil, Rosehip Oil and other oil-based ingredients.
Despite being an oil serum, it is designed to blend smoothly and lightly into the skin rather than leaving an excessively heavy finish.
The result is a moisturised complexion with a fresh, supple and luminous appearance.
Natural Essential Oil Aroma
The aromatic blend uses natural essential oils including:
- Rosehip
- Lavender
- Geranium
- Rosemary
The botanical aroma adds a relaxing sensory element to the skincare routine without making therapeutic or mood-treatment claims.
Suitable For
Doctor K C Concentrate Oil Serum is particularly suited to:
- Dry or moisture-depleted skin
- Dryness-related visible pores
- Dull-looking skin
- Uneven skin texture
- Excess shine and sebum concerns
- Skin prone to roughness
- Loss of firmness
- Seasonal dryness
- Skin exposed to environmental stress such as pollen
- Those looking for vitamin-rich facial oil care
It can also be used for dry elbows, heels, scalp and hair ends.
Texture
A lightweight botanical oil serum that spreads smoothly and absorbs comfortably into the skin.
It provides concentrated oil-based moisture without an overly heavy feel, leaving skin looking supple, smooth and radiant.
