she needs to hydrate from the inside as well as the outside, but this won't hurt her and basically will hopefully prevent further decline of the neck skin.

As a Derm., my question would be (typical doc lingo, sorry). Yes, certainly safe, but completely unnecessary on such young skin. Typically, a 15year old has sufficient elasticity on their collagen cells. So, while, it would provide no adverse effects, it also would not provide any benefit, except hydration.
