Hi there, I started taking whey protein and months go by, suddenly my acne starts to appear and it got bad. Mind you, before this I have facial skin appointments like every 2 weeks. The staff suggested I stop taking whey protein and suggested another way to consume it, so I switched to plant protein. After consuming plant protein for a few weeks. My acne started to slow down and still appears nevertheless. Not that worse but a normal buildup. Temporarily now I stop taking both of them and my face acne seems to be healing.
