I have never been able to justify 'high-end' skincare, cosmetic or haircare products as a mother of three. Now at 40, I am really trying to be intentional about my own selfcare. I tried several of Kajinoor's products and I must say all have been life-changing (going from drugstore brands to high-end) but the retinol especially. If I use it the night before, I can immediately notice a change in my skin the next morning! My 'thinking wrinkle' between by brows has nearly disappeared and also my frown lines! This product DEFINITELY reduces the appearance of fine lines and has never bothered my skin, no rashes either (I don't really have sensitive skin though), be careful using any retinol product in the sun though!!!
