Open Formula - Ruzan review for Retinoid Serum

I find this serum gentle yet quite effective. At the beginning I had a reaction but it was my fault, I kept using strong actives. After my skin healed, it is gentle on my skin and feels soothing. I love it comes in an oil form, little goes long way and it's nourishing for dry skin. It evens my skin tone and makes it plump. I overall think my skin looks better since I started to use this product
