Honestly don’t bother..
Honestly don’t bother..used the growth serum for months, zero difference to my fine lines. Bought the MAC cream which is in a jar so obviously even if it would be an efficient formulation with the repeated air and light exposure the growth factors would become ineffective after a short period of time anyway.. not to mention how unsanitary a jar is. The other cream has fragrance (in 2025..) so didn’t even bother with that one. Overall quite an underwhelming experience.
