Hi! First, I just wanted to let you know that I got your first message too but my response was too long to post as an answer so if you want to give me your e-mail that would be great!
I have used Yoghurt + Egg white + Lemon juice masks before that it did help my skin. Sometimes with masks such as these that ‘draw’ out impurities your skin might breakout slightly initially because the toxins are being pulled to the surface. It should clear up, but if it doesn’t perhaps it is a skin sensitivity to the dairy or citrus.
