Development Background

While azelaic acid is widely used overseas for various skin concerns, in Japan, high-concentration formulations have often caused irritation, making it difficult for those with sensitive skin to use.

Additionally, many individuals with easily irritated skin have expressed interest in azelaic acid but hesitated due to concerns about irritation, or desired a product that combines moisturizing care with functional skincare benefits.

Four Key Features

[Feature 1] Pure Azelaic Acid※2 Encapsulated in Liposomes

Instead of azelaic acid derivatives, the formula uses pure azelaic acid※2 encapsulated in liposomes. By encapsulating the ingredient into ultra-fine particles smaller than pores, the formulation minimizes irritation while effectively delivering it to the stratum corneum.

[Feature 2] Hydrating Formula to Counteract Azelaic Acid’s Drawbacks

While azelaic acid is beneficial, it can also cause dryness. The formula includes hyaluronic acid※3—known for its ability to retain up to six liters of water per gram—and ceramides※4, natural moisturizing components of the skin, to counteract the drying effects of azelaic acid.

[Feature 3] Thoughtfully Designed Texture for Any Occasion

To maximize the benefits of the ingredients, the product features a unique formulation that delivers a lightweight, non-greasy texture—ideal for daytime use and under makeup. Its light milk texture is suitable for both morning and evening routines.

[Feature 4] Ingredients to Help Prevent Skin Irritation

Chamomile flower extract※5 and dipotassium glycyrrhizate※6 are included to help prevent skin irritation. These ingredients support the maintenance of sensitive skin and make daily skincare easier to sustain.

Ideal For:

- Individuals with sensitive or delicate skin
- Those with skin prone to sensitivity
- People interested in azelaic acid but hesitant to try due to irritation concerns
- Those who have tried azelaic acid but found it too irritating

How to Use
