Our Products formulations contain high concentrations of active natural extracts, their stability cannot be guaranteed if housed in plastic so we use laboratory standard amber glassware, better for our products and better for our beaches. However, I do like to remind all our customers to take care with the glass in their bathroom; slow down and don’t be in such a rush to clean yourselves! As with any skin care products please remember to carry out a skin compatibility test before use – With Kind Regards Dom Bridges
