Why You'll Love It
Targeted Care for Dryness-Related Visible Pores
Doctor K developed C Control Repair Serum with adult pore concerns in mind, particularly pores that become more noticeable as skin becomes dry and its texture loses uniformity.
The formula delivers moisturising ingredients into the stratum corneum, helping condition uneven texture and leave skin looking smoother, more refined and firm.
The product's pore claims specifically refer to the appearance of pores caused by dryness.
1.5× Vitamin C Derivative
At the heart of the formula is Magnesium Ascorbyl Phosphate, a Vitamin C derivative used as a moisturising ingredient.
The updated formula contains 1.5 times the amount found in the previous Doctor K Control Essence, strengthening the brand's vitamin-focused approach to dryness-related pore and ageing care.
Eight Cocktail Vitamins
Doctor K's proprietary Cocktail Vitamin approach combines eight vitamin-related moisturising ingredients:
- Magnesium Ascorbyl Phosphate
- Retinyl Palmitate
- Glucosyl Hesperidin
- Sodium Riboflavin Phosphate
- Sodium Tocopheryl Phosphate
- Tocopheryl Acetate
- Pyridoxine HCl
- Cyanocobalamin
Together with Glutathione, these ingredients provide intensive moisture care to the stratum corneum, helping improve the appearance of dryness, uneven texture and lack of radiance.
Vitamin A + Vitamin B + Vitamin C Care
The formula brings together several vitamin families rather than relying on Vitamin C alone.
Retinyl Palmitate is a vitamin A derivative used here as a moisturising ingredient. It should not be confused with pure retinol.
The formula also contains Vitamin B-related ingredients including Sodium Riboflavin Phosphate, Pyridoxine HCl and Cyanocobalamin, alongside its Vitamin C derivative.
Glutathione
Glutathione is included as a moisturising ingredient.
It works alongside the Cocktail Vitamin complex as part of Doctor K's approach to moisturising skin affected by dryness-related dullness, uneven texture and lack of firmness or radiance.
NMN Derivative & Tripeptide
For age-related skincare concerns, the serum also incorporates two moisturising ingredients:
NMN Derivative — Dihydronicotinamide Riboside Acetyl Tri-t-Butyl Tryptophan
Tripeptide — Palmitoyl Tripeptide-5
These ingredients help moisturise skin showing visible signs associated with dryness and ageing, supporting a smoother and firmer-looking complexion.
12 Plant-Derived Skin-Conditioning Ingredients
The formula contains a broad botanical complex of 12 plant-derived skin-conditioning ingredients, including:
- Licorice Root Extract
- Mandarin Orange Peel Extract
- Artichoke Leaf Extract
- Centella Asiatica Extract
- Geranium Robertianum Extract
- Green Tea Leaf Extract
- Japanese Knotweed Root Extract
- Scutellaria Baicalensis Root Extract
- Bilberry Leaf Extract
- Chamomile Flower Extract
- Rosemary Leaf Extract
- Cysteine/Oligomeric Proanthocyanidins
These ingredients complement the vitamin-focused formula to help maintain healthy-looking skin.
Caffeine & Glycine
Caffeine and Glycine are included as skin-conditioning ingredients, contributing to the serum's focus on the appearance of smooth, refined and firm-looking skin.
Suitable For
Doctor K C Control Repair Serum is particularly suited to:
- Dryness-related visible pores
