Teenage daughter wants a retina prescription to prevent Future aging?

[Patentrain]

My Daughter who is 16 wants a subscription to one of these retin a services from Christmas. She has lovely skin and only gets the odd spot but she wants to keep her skin as good as possible for as long as possible. I think she is being influenced by youtubers Who are probably in their late 20s but most of their content is pitched at teens.

Also her Aunt, my older sister has used prescription strength retin a since her teens (initially for mild acne) and in her mid 40s has absolutely no lines, pigmentation or sag. She is 2 years older than me and looks about 2 decades younger!

I don’t know what to do. On one Hand it seems harmless enough but It seems very young for such high grade stuff and also she’d have to be very diligent about sunscreen. I just don’t know if she’d wear sunscreen everyday without me nagging!

Would it be unreasonable to refuse her request?

Do you have to pay for it? If you do then I'd say no, it doesn't sound like a good idea. I would say the wearing of suncream every day is also doing your sisters skin a world of good, it's the sun that ages our skin more than anything.

If it's free, which I cant imagine it would be, then she doesn't actually need your consent, she just needs to discuss it with her gp who can give her a prescription without asking you. (In the UK, not sure where you are)

I'd feel quite sorry for your dd if how to avoid aging is so important to her at 16 and I'd worry about her self esteem in general. I'd also worry about how long she spends on Instagram etc.
