My PFB DS is 13yo and I've noticed his skin is starting to get a bit greasy/blackheady.
I want something he can use in the shower (or bath.He's more of a bather than a showerer).
I don't want to make a big thing of it, teens have enough to worry about, but I'd rather he gets to grips before one of his mates mentions it.
In the past I've bought him Witch Hazel foaming wash but I think he needs something gritty.
His dad's got RSC (Real Shaving Company) facescrub.
Would that do or be too harsh?
So, what do your teens buy (or more likely, you buy it, they use it) 
TIA
