The derma roller is the hottest item right now among beauty enthusiasts. Also known as “skin roller,” the derma roller is a small handheld tool used in microneedling, skin needling or collagen induction therapy (CIT).
The derma roller is covered with thousands of thin and tiny microneedles. When used to roll on the skin, it creates tiny punctures on the skin’s epidermis. These micro-punctures trick the skin into regenerating, because the body thinks that the skin has been injured. As the derma roller create those tiny punctures, it stimulates the formation of new natural collagen and elastin which helps in rejuvenating the skin. The tiny infiltration channels also allow faster and more effective absorption of active ingredients applied on the skin.
But as with most things, there is a limit to the use of the derma roller. Otherwise, too much rolling won’t render the derma roller effective any longer. So, how to tell when it is time to replace your derma roller? How long do derma rollers last?
It depends on a lot of a factors. One of them is the manufacturer’s instructions. For example, Dr. Roller’s manual says that the derma roller should be disposed of after six months of use. But then, it depends on how often you are using it. If you use it too much, the needles will start to lose their original sharpness, and dull needles are ineffective in making micro-penetrations in your skin’s outer layer. Another, the longer the derma roller needle is, the more necessary that you should change it often.
The price point of the derma roller can also be a good determinant of its quality. Usually, the more expensive the derma roller, the higher quality it has – and therefore, the longer it should last. Higher quality derma rollers should have needles that are constructed from excellent materials. Most needles are made from medical-grade stainless steel, but there are others which are made from titanium alloy.
The following lists the pros and cons of stainless steel and titanium microneedles:
1. Stainless steel microneedles
- Extremely sharp
- Extremely hygienic
- Easy to clean and to sterilize
- Not as durable as titanium
- Prone to wear and tear
2. Titanium alloy microneedles
- Extremely durable and robust
- Highly resistant to wear and tear
- Highly resistant to bending
- More aesthetically pleasing, particularly the gold-plated varieties.
- Requires more cleaning and sterilizing
- Needles not as sharp as stainless steel
Another factor that determines a derma roller’s useful life is the way you use and maintain it. Clean and sterilize your derma roller regularly (before and after use) and do not leave it lying on dirty surfaces. These tips will help extend the useful life of your derma roller.
