Milk of magnesia for skincare?
So I live in NC on the beach and it's extremely hot and humid here and I've been fighting with my makeup trying to avoid it from sweating off. I read online that using milk of magnesia as a primer works great at soaking up oil and preventing your face from sweating like crazy. There were also a ton of articles listing all the benefits of using it on your skin, like helping to clear up acne, stop excessive oil production, help clear up blackheads, etc. Then, of course, there are many other articles saying it's a terrible idea to use milk of magnesia on your face because it has a pH of 10.5. I understand it's usually best to stick with skincare products that are around the same pH of your skin but is MOM really going to cause extreme problems or issues?
