Our Expert View

Revolutionising the world of anti-ageing devices, 21Skin’s radio frequency device is the only home-use device on the market that harnesses salon-standard Unipolar technology - reaching the deepest layers of your skin.

21Skin works by remodelling collagen fibres and kickstarting the production of collagen and elastin. In doing so, the device helps to tighten sagging and loose skin, and also means visible signs of ageing such as wrinkles are smoothed out too.

How does it work?

21Skin harnesses radio frequency, a low energy electromagnetic radiation which stimulates collagen production and remodels collagen fibres. Working deep below the skin’s surface, 21Skin’s patent-pending 40.68MHz frequency and 30W of power effectively and safely tightens your skin to reverse signs of ageing.

Unipolar Radio Frequency

21Skin harnesses a type of radio frequency technology called Unipolar (or Monopolar), which is used in most salon radio frequency machines. Unipolar radio frequency travels deep into the sub-dermal layers of the skin to stimulate collagen production.

Unipolar devices use one electrode as opposed to two (seen on most other home-use radio frequency devices). Having just one electrode helps the radio frequency directly penetrate downwards to the targeted area, reaching the deepest layers of the skin.

How to use

Step 1: Attach one of the handsets to your 21Skin device. The flat one is for the flat areas of your face, use the other handset for smaller areas such as around the eyes and mouth.

Step 2: Apply a generous layer of DermaDeep Serum over the treatment area.

Step 3: Choose a power level.

Step 4: Press and release the button on the handset to activate radio frequency.

Step 5: Move the handset slowly in small circular motions.

Step 6: Once you’ve heated the skin to the temperature that’s comfortable for you, repeat the process over the whole area to be treated.

Step 7: Turn off the device and wipe off any excess serum from your face and the device.

Step 8: Cleanse your face and follow up with your favourite moisturiser.


21Skin’s sleek design makes this powerful device convenient and simple to use. A full facial treatment only takes 20-30 minutes, and only needs to be used twice a week for best results.

The device also comes with the brand’s DermaDeep Serum, which must be applied before your treatments to ensure optimal conductivity of radio frequency into the skin.
