Radara’s ultra-thin flexible, polymer patches are coated with microscopic plastic structures (similar to needles) less than half a millimetre in length. They feel bumpy to the touch and are not sharp or painful at all. When applied, these painlessly create thousands of tiny micro-channels in the skin, helping to kickstart the skin’s own natural regenerative processes including new collagen formation to repair the ‘damage’. Although the patches contain no adhesive, the serum will hold the patch in the correct position.
