Vitamin A or Retinol works as an anti-oxidant for the skin, disarming free radicals that cause tissue and cell damage. It smoothes wrinkles and lines gradually, improves moisture and elasticity, diminishes sun damage and provides glow to the skin complexion. In addition, vitamin A increases the skin's cell turnover, while also boosts collagen, resulting in a more youthful overall appearance. 

As well as working to diminish stretch marks, vitamin A assists the skin's natural healing processes. This vitamin and its derivatives have displayed beneficial effects in controlling agne and in reversing skin damage caused by environmental factors.
