My mother bought this range as she wants to combat ant-ageing, and she had mentioned that she felt the necessity of all four products instead of using just one, as they all highlight & the results are more beneficial with the entire range. I had been using these products for a little out of curiosity & I have heard that using anti-ageing products from a young age is so important to combat early signs. All the product smells similar & the black & white packaging is super professional and simplistic (less is more). This cleanser isn't as 'gentle' as I thought it was going to be - it also would remove my makeup if I washed my face with it. My tube never leaked and it always made my face feels fresh and very clean right after using it.
