What are these white bumps on my upper lip? what are they caused from and can I prevent them with out special products?
The best way to reduce the likelihood is to work clean and to exfoliate between treatments. The white pustules are usually caused by inflammation and infection in the hair follicle.
Using witch hazel to cleanse before and after can help, and wash your hands well before starting. You can also use an antibacterial soap.
If you do get pustules despite all that, the best thing I’ve found is Tend Skin, but you can also use acne medications like benzoyl peroxide.
The main thing is not to scratch or pop them, which can sometimes make things worse or even lead to scarring or skin discoloration.
