This is my favourite product from the Hydroboost range, and I've repurchased it twice.
I'd been looking for a cheaper product to do what my Clarins HydraQuench cream does, and while this isn't AS good (nothing will be, but for R550 a tub, you're getting what you pay for I think), but this comes the closest of any other product I've tried.
It hydrates and soothes, gives enough nourishment to me at night during summer, and I pop it on under a richer moisturiser even now at night to give an extra boost of hydration.
I'll definitely repurchase again.
