Microneedles, as the name suggests, are tiny needles less than 1 mm in diameter and less than 15 mm in length. They are usually composed of multiple groups of fine needles arranged, used to puncture the skin surface, stimulate the skin, thereby promoting the growth of skin collagen, skin cell metabolism, etc., to tighten the skin, improve skin tone, reduce wrinkles and other effects.
There are many kinds of materials for micro needle heads, the most common are titanium and stainless steel.
1. Titanium material
Titanium has the characteristics of light, tough, corrosion resistance, etc., and has become a popular choice for making micro-needle heads. The titanium microneedle head is light in weight, more flexible in use, and will not cause excessive skin irritation. In addition, titanium metal has low water absorption, good antibacterial property, and is not easy to produce bacterial growth, which can effectively prevent infection. However, titanium is expensive and the cost of use is relatively high.
2. Stainless steel
Stainless steel is also a material that is often used to make microneedle heads. Stainless steel microneedle head has the characteristics of high hardness and long life, and its price is cheaper than titanium metal. However, the needle weight of stainless steel is relatively heavy, which requires greater force when used and causes greater irritation to the skin.
In summary, different materials of micro needle heads have their own advantages and disadvantages, and should be reasonably matched according to the user's personal situation, needs and doctor's choice.
