[Development Background]

As interest in aesthetic medicine grows, so does consumer demand for professional-grade skincare at home. Vitamin C, in particular, is widely recognized by aesthetic medical professionals as a key ingredient supporting post-treatment care and daily anti-aging*3 routines.

However, some users remain concerned about issues such as skin irritation or dryness when using vitamin C products.

Developed exclusively for aesthetic medical institutions, VC SERUM DR 34 prioritizes both concentration and purity, achieving a high-concentration formula that is gentle and minimizes irritation.

Suitable for both first-time users and existing vitamin C enthusiasts, this serum can be incorporated into daily skincare routines.

[Key Features of VC SERUM DR 34]

◆ 34% Pure Vitamin C Serum

Dr.MESOCEUTICAL® is the first to successfully formulate a 34% concentration of pure vitamin C—over 99% purity—into a stable serum through years of dedicated research.

Using proprietary penetration technology, this high-concentration pure vitamin C penetrates deep into the skin, refining skin texture, enhancing firmness, and promoting a clear, radiant complexion*5 by reducing dullness*4.

*4 Appearance of skin lacking luster

*5 Dull, dehydrated skin becomes hydrated and refined, resulting in a brighter, more luminous appearance

◆ Proprietary Penetration Technology "VCore-XTM"

The serum base is amphiphilic—compatible with both water and oil—enabling active ingredients to penetrate beyond the lamellar layers of the skin*6. This unique, anhydrous formulation ensures pure ingredients remain effective while delivering them deep into the skin.

This advanced technology ensures efficient delivery and optimal performance of active ingredients.

*6 Up to the stratum corneum

◆ Formulated to Minimize Skin Stress

VC SERUM DR 34 features a "6-Free Formula"—free from preservatives, antibacterial agents, alcohol, and other common irritants. By including only essential ingredients, the simple formulation reduces skin burden.
