Both my sister and I have tested this cream of Florena, and each with different results. I'm 30 and I still have no visible wrinkles. My sister is 40 and also very slim. Fold has been rather small laugh lines, etc. A visible reduction of wrinkles, we could not tell, but my sister had to stop after a short time with the towel as their (already very sensitive) skin has a negative reaction. She got redness and pimples away.
I myself have seen no such reaction. Although my skin is also sensitive and can react quickly to unfamiliar incompatible products, but the Florena Creme is not among them. My skin is not as dry, but slightly softer. After prolonged use, I can say for me that my skin the cream tolerates definitely.
