Seborrhoeic keratoses are harmless, raised spots that often look slightly crusty or stuck onto the skin, usually appearing as brown or skin-coloured bumps as we get older. While completely safe, they can be frustrating if they catch on clothing or feel unsightly. Advanced electrolysis provides a quick and gentle way to clear them. A tiny probe applies a brief, targeted electrical current to carefully loosen the spot from the surface of your skin. A small dry crust forms where the spot was, which naturally flakes off over a few days to leave smooth skin underneath.
