Researchers developed tattoo inks that can be switched on with ultraviolet light and made to disappear in sunlight; tests found the colours remained switchable in skin for up to 2.2 years, opening possible medical uses
- Researchers hope to bring additional colours to market and reduce production costs as development progresses.
- Questions about long-term safety, performance and practical use will also matter as the technology advances.
- A tattoo has traditionally been a commitment etched into the skin, with removal often involving multiple laser sessions, discomfort and considerable expense.
