About the product

What Is It:

Meet HA-EGF, the star ingredient in the WONJIN EFFECT Ulthemage Ampoule, and the brand’s first independent ingredient developed through joint efforts between the WONJIN Medical Group and Harvard Medical School. This unique ingredient combines the plumping effects of Hyaluronic Acid and the anti-aging Epidermal Growth Factor, and is complimented by a myriad of classic K-beauty ingredients, such as brightening niacinamide, skin-conditioning propanediol, nourishing olive and macadamia seed oils, and more.
The Ulthemage Ampoule is divided into three 12ml vials, each containing 10-days worth of product, and comes in a satin-rose box with a reusable applicator. You’ll notice that the liquid inside the vial is separated into three distinct sections. The top yellow-hued layer is the VitaSerum, which boasts pure Vitamin C and a complex of 8 vitamins that revitalize and reduce blemishes on the stratum corneum level.
The middle, clear layer is the star ingredient, HA-EGF, which stimulates the epidermal growth factors in the epidermal basal layer—the deepest layer of the five epidermal layers—to target and improve your skin at its core. EGF alone can produce skin-improving results, but it also has a short half-life and lacks in its ability to effectively absorb into skin. That’s why WONJIN and Harvard put their heads together to combine EGF with Hyaluronic Acid, a beloved skincare ingredient known to quickly absorb into skin and hold over 1,000 times its weight. That means intense anti-aging and skin-plumping action on a deep epidermal level!
Finally, the bottom, turquoise layer makes up the Matrixyl Essence, which features three types of collage and Matrixyl 3000, an anti-aging peptide that restores skin elasticity and your skin’s protective moisture barrier.

Our insight:

The Ulthemage Ampoule has a light fragrance and a fluid texture that absorbs quickly into skin for a non-sticky finish.

How to use:

Make sure to give the vial a nice shake to blend the three layers together. After cleansing and applying toner and/or essence, drop a moderate amount of the ampoule into your palms or directly onto your face and spread evenly. Gently pat in to increase absorption.
