[Restock on 4/7 (Tues)] New Azelaic Acid Serum for Sensitive Skin, Sold Out in 3 Days After Pre-sale, is Back in Stock. A 주목 Product for Preventing Spring/Summer Skin Issues.

Background of the Presale Sellout

'Advanced Essence RO' combines 10% concentration azelaic acid with a serum formulated with five types of human ceramides using Cher-Couleur's unique formula. While items containing azelaic acid are gaining attention from those concerned about sebum, skin roughness, and texture, it is also an ingredient that can be irritating depending on skin type.

DSR responded to voices saying, 'I want to try high-concentration azelaic acid but I'm worried about irritation,' and 'I want to check compatibility with a small amount first.' By offering a 10mL mini-size at a special price ahead of the launch, the response exceeded expectations, leading to a sellout.

Features of Advanced Essence RO

### Formulated with 10% Azelaic Acid to smooth skin concerned with sebum, roughness, and texture

'Advanced Essence RO' is a serum containing 10% concentration azelaic acid. It was designed to strike a balance between 'sustainability' and 'responsiveness,' based on feedback that high concentrations can be irritating and low concentrations can be unsatisfying. It aims to prevent sporadic skin roughness, prevent skin troubles caused by sebum, care for skin texture, and lead to a radiant complexion by refining the skin's surface.

### Formulated with 5 types of human ceramides to support the moisture barrier

Focusing on the moisture barrier, which is crucial for sensitive skin, it is formulated with five types of human ceramides: Ceramide EOP, Ceramide NG, Ceramide NP, Ceramide AG, and Ceramide AP. Considering the dryness that can be a concern when using azelaic acid, we aimed for a formula that protects the skin with moisture while being used.

### Formula designed with skin sensitivity in mind, including being oil-free and alcohol-free

This product is paraben-free, oil-free, colorless, fragrance-free, mineral oil-free, and alcohol-free. Furthermore, we have minimized glycerin to pursue a user-friendly feel for those concerned about sebum or who dislike a heavy sensation. Also, considering the sandy texture or pilling that can be a concern with azelaic acid products, we have created a smooth, easily spreadable texture.

### Also contains skin-conditioning ingredients like Niacinamide

In addition to azelaic acid, it contains skin-conditioning ingredients such as niacinamide, Salix Alba (Willow) Bark Extract, Tomato Fruit Extract, Saxifraga Sarmentosa Extract, and Chlorella Extract. The formula is designed to be easily incorporated into daily skincare, keeping skin prone to recurring roughness healthy.
