"I do have concerns about them using ingredients like vitamin C, vitamin A (retinoids) and exfoliating acids like AHAs and BHAs."

As someone who's 'into' skincare, it also happens that the ingredients mentioned are also amongst the best treatments for blackheads, spots, sebaceous filaments and other assorted teenage/hormonal changes skin issues - I suspect this article is not about ageing, but about "youngsters" being more educated about what they need!

Vit C has also been shown to help boost spf's, so is something recommended to anyone at any age (if your skin 'gets on' with it).

This is a stupid article, as Guardian subscriber I'm very disappointed, it's a 'nothing' article that I'd more expect of the Mail!
