Stabilized hyaluronic acid (S-HA) is used for soft tissue expansion and can also be used for skin hydration. According to previous reports, the injection volume of each injection for skin hydration is 0.02 cc or more. Clinically this is an excessive amount for this purpose, so we have introduced a new method for skin hydration using particle-shaped stabilized hyaluronic acid (S-HA) injection.1,500 patients who underwent 1,000 injections of 1 cc of stabilized hyaluronic acid (S-HA) were analyzed. Patients were examined 1, 2, 6, 12, and 24 months later. Changes in skin texture were determined by roughness and shape of skin, skin hydration due to electrical resistance, skin thickness and biopsy by ultrasound imaging. An intra-individual study was conducted to compare changes in skin texture between dermal injection and subdermal injection.The roughness of the skin improved considerably after this process. Electrical resistance also decreased. Face and hand skin thickened about 4% after dermal injection. The injection depth was confirmed by biopsy. There was no significant change in skin thickness after subcutaneous injection of stabilized hyaluronic acid (S-HA), which only replaced liquid volume. Dermal injections caused changes in both skin texture and thickness.Skin texture was improved after stabilized hyaluronic acid (S-HA) dermis injection (0.001 cc for each injection) in 1000 particle form. Deeper injections only changed the fluid level and did not improve skin texture. The use of syringes or mesotones is recommended for this purpose.안정화 히알루론산(S-HA)는 연조직 확장에 사용되는데 피부수화에도 사용될 수 있다. 이전의 보고에 따르면, 피부 수화를 위한 각 주사의 주사량은 0.02cc 이상이다. 임상적으로 이것은 이 목적을 위해서는 과도한 양이므로, 본 발명자는 피부 수화를 위해서 입자형 안정화 히알루론산(S-HA) 주사를 사용하여 새로운 방법을 도입하였다.1cc의 안정화 히알루론산(S-HA)을 1,000회 주사를 맞은 1,500명의 환자를 분석하였다. 환자들은 1, 2, 6, 12, 24 개월 후에 검사되었다. 피부 질감(skin texture)의 변화를 피부의 거친 정도와 형태, 전기 저항에 의한 피부 수화, 초음파 영상에 의한 피부 두께 및 생검을 고려하여 밝혔다. 진피주사(dermal injection)와 피하주사(subdermal injection) 사이의 피부 질감의 변화를 비교하기 위
