Retizen in Seoul — a collagen skin booster that firms from within

A true collagen skinbooster that firms from within the skin

Retizen — Better Face Line at VOS Dermatology Clinic, Gangnam Seoul

Overview

Retizen in Seoul (also known as Laetigen) is a collagen skin booster: instead of asking your skin to make collagen from scratch, it replenishes intercellular components directly, improving elasticity, tone and pore appearance. It is one of the gentler options at VOS, often chosen by people who want a treatment with very little pain.

Dr. Hongseok Kim recommends Retizen for dry, dull skin, sagging pores and fine lines, and for thin skin with low elasticity. Improvement is usually felt within 1–2 weeks and lasts around 6–12 months with maintenance; results vary by person.

How it works

What Retizen does in the skin

01Enhances skin functionality by replenishing intercellular matrix with 100% pure real collagen.

Laetigen is a collagen booster injection that directly replenishes Type 1 collagen, a key component of the dermis layer. Healthy skin has a firm structure in its layers, but as we age, the dermal layer deteriorates, collagen production declines, and elastin decreases. This leads to wrinkles and dryness in the epidermis. Laetigen restores the skin’s natural strength by delivering 100% pure Type 1 collagen directly into the skin layers. It rebuilds the weakened structure and enhances the skin’s inherent functionality. Directly inject collagen into the weakened skin layer, rather than boosting collagen production. Collagen, elastin, and hyaluronic acid levels increase, filling the gaps between cells to enhance elasticity and radiance.

02A safe injection produced through a sterilization process and proprietary purification process.

Laetigen, composed of 100% Type 1 collagen—the primary component of the human dermal layer—is produced through a sterilization process to ensure safety. This product is made using a advanced multi-stage filtration system to extract high-purity collagen, resulting in a neutral formulation that minimizes post-treatment swelling and discomfort. Additionally, it is certified by the U.S. FDA, offering enhanced reliability and trust.
