After suffering from acne for such a long time (>12 yrs) I was told about this product but was initially hesitant to buy. Many acne products I''ve used for >12yrs promised big results but always fell short on their promises. I eventually caved and bought the complete SkinTx package (with the lightening cream and all). I started using SkinTX product since 2012 and although it''s expensive i haven''t used anything else. Yes it''s expensive but totally worth the money. This product is concentrated so you only need a small amount each time. One bottle usually lasts me about 3 months or more. I would highly recommend this to anyone suffering from acne.
