Retinal content testing service

Postby visanu » Tue Jan 23, 2024 11:13 am

Hello, I would like to ask if the company has a service to check the amount of Retinal from creams that are made to order.

I want to test if after using the cream for 6 months, is there still some amount of Retinal left?


thank you
