Seems to be doing the job. It does seem very similar to 4Life TF which I took for some years. Both make my skin dry.

Thanks for your feedback!

I'm passing through a time with weak immune system, so I tried this but didn't noticed any improvement. I think I should stick to the basic: Zinc, Ashwagandha, Glutamine and Vit C.

Thanks for your feedback!
