This technology can significantly improve the firmness and luster of the skin, and help restore facial rejuvenation. Dermal injection is simple to operate, short recovery period, and high safety. It has become one of the most popular medical beauty projects. It not only improves skin quality, It can also enhance the overall facial contour, make the skin glow, and truly reveal the mystery of facial rejuvenation.

什么是真皮注射？

真皮注射,顾名思义，是指将药物或生物活性物质直接注入真皮层的一种注射技术，与传统的皮下注射不同，真皮注射更注重药物在真皮层的精准分布，从而达到更自然、更持久的美容效果。

真皮层是皮肤的重要组成部分,富含胶原蛋白、弹性纤维和毛细血管，通过将特定成分注入真皮层，可以刺激collagen regeneration、改善皮肤弹性、减少皱纹，甚至促进色素沉着的均匀分布。

Indications for dermal injection

1. facial rejuvenation
   Dermal injection is often used for facial rejuvenation treatment, such as filling in fine wrinkles, improving skin slack, and improving facial contours. Compared with traditional filler injection, dermal injection pays more attention to creating a layered feeling and has a more natural effect.

2. large pores
   Dermal injection can evenly distribute the drug around the pores, helping to shrink pores and improve rough skin problems.

3. skin pigmentation
   For pigmentation problems such as spots and acne marks, dermal injection can accurately inject whitening ingredients or photosensitizers into the dermal layer to promote melanin metabolism and achieve uniform skin tone.

4. acne scars
   Dermal injection can be used to treat depressed acne scars, improving skin surface irregularities by filling depressed areas.

1. 效果自然
   Dermal injection focuses on layering and uniformity, avoiding the "fake feeling" or "agglomeration" phenomenon that may occur in traditional injection, and the effect is more natural.

2. 恢复期短
   Because dermal injection is a minimally invasive operation, the postoperative recovery period is short, and it usually only takes a few days to resume normal life and work.

3. 安全性高
   Under the operation of a professional doctor, the risk of dermal injection is low, and adverse reactions such as redness, swelling and bruises are not likely to occur after surgery.

4. 适用范围广
   Dermal injection can be used not only for facial beauty, but also on other parts of the body, such as neck, hands, etc., to meet the needs of different beauty seekers.

Operating procedures for dermal injection

1. 术前评估
   Doctors will formulate personalized treatment plans based on the beauty seeker's skin condition, facial characteristics and beauty needs.

2. local anesthesia
   In order to reduce discomfort during injection, the doctor will apply local anesthesia at the injection site.

3. 精准注射
   Use thin needles to inject the drug evenly into the dermis layer. The depth and dose must be strictly controlled during the injection process to ensure maximum effect.

4. 术后护理
   Avoid pressing or rubbing the injection site after injection, keep the face clean and avoid infection, and doctors usually give detailed advice on postoperative care.
