You may notice that your eyebrow area feels a little bit sensitive just after hair removal and Beauty Image explains that you should go makeup-free if possible for 24 hours after eyebrow treatments to avoid a negative skin reaction. Dr. Desai further explained to Glamour, "Tweezing, waxing, and threading all have a tendency to cause breakouts and products like brow gel can also clog and block pores in turn leading to blackheads and inflamed breakouts." 

Fortunately, as Total Beauty points out, there are an abundance of brow products on the market that you can tailor to your specific needs including your skin type, but even if you find a product that works, it's important to not just remove the makeup on your face at the end of the day, but also to keep your brushes, wands and beauty applicators clean. According to Medical News Today, if you don't clean your brushes and applicators regularly, they can transfer acne causing bacteria as well as dead skin, dust and pore clogging residue onto your brow line resulting in breakouts and irritation.
