Crystal Clear is amazing. I’m so glad I found them. Tanya gives great customer service and nothing is too much trouble. Sell all the best brands but especially Dermaviduals - it’s my favourite and gives the best results.
I recently dropped into Crystal Clear Skin for some advice about Jane Iredale products. I was very impressed by the friendly care and helpful support I received. This is a lovely salon staffed by caring and knowledgeable therapists, and well worth a visit. Highly recommended!
I purchased products from their store and was very happy with my experience. The sales were amazing, shipping was super fast and I especially loved the personal touch with the hand written note. I've even recommended Crystal Clear Skin to my family and friends.
I have been buying online from Crystal Clear Skin for so long. They're so amazing to deal with, I have sent them many emails with my skin concerns and thoughts and they're always to helpful. Tania and the rest of the staff are professional to deal with and very knowledgeable about the product they sell and skin care in general. Highly recommend!
