n the 1970s, scientists testing anti-ageing treatments uncovered the astounding effects of cow collagen injected into human skin. Previously they\'d experimented by injecting substances such as paraffin and silicone into the skin - however, it turned out that the former was highly toxic and cancer-causing, and the latter was eventually banned for its high abuse potential. Collagen offered the safest, most effective option yet. Over the years, the collagen solution has been developed and improved to an increasingly high standard and, today, dermatologists more commonly use a synthetic version grown from human tissue in a lab.
Collagen injections last up to six months and are most effective on:
- frown lines
- crow\'s feet
- forehead lines
- lip border
- scar filling
- vertical lip lines.
Collagen injection brand names include:
- Zyderm®
- Zyplast®
- Cymetra®
