A derma roller looks and functions like a paint roller, except it’s less fluff and more spiky. The handheld device is made with a cylindrical end sporting tiny microneedles around its circumference. These come in different lengths, usually between 0.2mm and 1mm, for different levels of intensity. 

As with the use of any beauty tool, you should first cleanse your face thoroughly as this prevents the needles from spreading bacteria.

Then, apply an essence or toner to help skin stay soft and prepped.

Gently work the derma roller with one hand in a systematic, horizontal approach from the centre of your face outwards and on both sides. Start at your forehead, work your way down to the chin and avoid the eye area. 

The theory is derma rollers create controlled injuries to the skin in the form of micro punctures. This sends signals to your body for a boost in collagen and elastin production.

Numerous studies show an improvement for a range of skin conditions such as acne scarring, melasma and hair loss along with overall plumping and firming of the skin.

However, the studies admit larger controlled clinical trials are required for more concrete conclusions.

Those with sensitive skin conditions such as eczema, psoriasis and acne cysts shouldn’t be derma rolling.

Also, avoid introducing derma rolling and retinol products at the same time. Starting both simultaneously may be too intense for the skin. Limit your sessions to once a week and use an SPF product for extra protection while your skin adapts.

Lastly, refrain from using derma rollers with a needle length greater than 1.5mm – they’re to be used by a professional.
