DSR Co., Ltd. (Headquarters: Suita City, Osaka Prefecture, Representative: Jiro Miyatake, hereinafter DSR) will restock the mini size of its new beauty serum 'Advanced Essence RO', to be released on April 14, 2026 (Tuesday) from the ceramide cosmetic brand 'Chercheur' for sensitive skin, at 12:00 PM on April 7, 2026 (Tuesday).
Background of the pre-sale sold out
'Advanced Essence RO' combines a 10% concentration of azelaic acid with a serum containing 5 types of human-type ceramides using Chercheur's unique formulation.
While items containing azelaic acid are attracting attention from those concerned about sebum, rough skin, and skin stiffness, it is also an ingredient that can easily cause irritation depending on the skin type.
In response to voices such as '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', DSR held a special pre-sale of a 10mL mini size ahead of the official launch, which sold out due to a response exceeding expectations.
■ Features of Advanced Essence RO
Contains 10% azelaic acid to smooth out skin concerned with sebum, roughness, and stiffness
'Advanced Essence RO' is a beauty serum formulated with a 10% concentration of azelaic acid.
Based on feedback that high concentrations tend to cause irritation, while low concentrations feel insufficient, it was designed aiming for a balance between 'ease of continued use' and 'effectiveness'.
It aims to prevent spotty skin roughness, prevent skin troubles caused by sebum, care for skin stiffness, and condition the texture to lead to glossy skin.
Formulated with 5 types of human-type ceramides to support the moisture barrier
Focusing on the moisture barrier, which is important for people with sensitive skin, it is formulated with 5 types of human-type ceramides: Ceramide EOP, Ceramide NG, Ceramide NP, Ceramide AG, and Ceramide AP.
Taking into consideration the dryness that tends to be a concern when using azelaic acid, we aimed for a formulation that can be used while protecting the skin with moisture.
