Are hydrocolloid spot patches a good way to target spots, or are they just a marketing gimmick? I tested a range of pimples patches on my acne-prone skin to find out.
According to consultant dermatologist Dr Justine Kluk, who specialises in acne treatment, hydrocolloid is the most important ingredient when it comes to spot patches. The substance forms a gel when mixed with water, and it’s often used in wound healing, as it creates a moist environment. They can “help by absorbing fluid [oil, sebum, dirt] from spots and creating a protective barrier, which speeds up healing and stops you picking – a big culprit for scarring”, explains Dr Kluk.
