2 in 1 plasma pen has three kinds of tips: 3pcs thin needle, 1pc thick needle, 3pcs ozone tips(large,middle,small). Ozone has strong oxidizing and bactericidal properties, which can effectively eliminate bacteria, viruses, and fungi.

When the pen comes into contact with the skin, the ozone helps to kill bacteria and viruses on the surface, making it an effective tool for sterilization and disinfection. This is particularly important during skin treatments, as it helps to prevent infections and promote faster healing.

In addition to its sterilizing properties, ozone also has anti-inflammatory and antioxidant effects. It can help to reduce redness and swelling after a treatment, as well as protect the skin from free radical damage. Ozone can also stimulate collagen production, leading to firmer and more youthful-looking skin over time.

It can offer various treatments for the skin, including:
1. Skin tightening: The plasma pen can help tighten loose or sagging skin by stimulating collagen production, resulting in a firmer and more youthful appearance.
2. Wrinkle reduction: The pen can target fine lines and wrinkles, smoothing them out for a more youthful look.
3. Scar reduction: The plasma pen can help reduce the appearance of scars, including acne scars, surgical scars, and stretch marks.
4. Pigmentation correction: The pen can target areas of hyperpigmentation, such as age spots or sun spots, helping to even out skin tone.
5. Skin rejuvenation: The plasma pen can improve overall skin texture and tone, leaving the skin looking brighter and more refreshed.
