Why should it be injected into the superficial dermis 1.2mm?
The thickness of the epidermis is 0.1-0.4mm, and the thickness of the dermis is 0.5-4mm. If it is too deep, the meat group will not see the effect. If it is too shallow, the metabolism will last for a short time. Getting older, the skin is getting older, the ability to lock water is getting worse, nutrients are lost faster, and regeneration is slow, so we need to directly inject the nutrients we need in the superficial dermis to maintain a better skin condition. The light injection product is a single component of broken uric acid, also known as hyaluronic acid, which is a water-locking factor for the skin. Hyaluronic acid is divided into three types of macro molecules, medium and small molecules. It plays a role in shaping and can exist in the skin for a long time. The small molecules do not contain cross-linking agents and can be absorbed by the skin. We use it for water and light. In order to meet higher needs, kinesin appears. To achieve all the desired effects, such as whitening, anti-epidemic, and pores, etc., hyaluronic acid and kinetic energy are the most common water-light needles that can be used as long-term high-end maintenance items.
