Ingrown hairs can lead to an infection, but at the very least they look bad and can become very tender or uncomfortable. This is especially troubling when they appear in noticeable places on your face.  Ingrown hairs need to come out. Once you notice an ingrown hair, stop shaving or waxing the area at once so that the hair has an opportunity to grow for a little bit. You should never break the skin or dig into it in order to reach an ingrown hair. Instead, you should let it come to the surface on its own so you don't do more damage to your skin.   The safest way to extract an ingrown hair is by pulling it out with tweezers. However, you have to wait for the hair to reach the surface on its own before you can do so. Apply a hot compress to the area a couple of times a day to encourage the hair to reach the surface. Sometimes the worst part about an ingrown hair is how it looks, especially when it is on your face for the whole world to see. Ingrown hairs can really irritate and damage healthy skin. Treat the damaged skin with some soothing aloe vera or a gentle moisturizer. In rare cases, you may need to go see your doctor for some antibiotics if your ingrown facial hair becomes infected. Since the ingrown hair creates an opening in your skin, it is possible for bacteria to seep into the hole and cause an infection. Whenever you have an ingrown hair, you should be vigilant in watching for signs of redness, swelling, and discomfort that last more than a few days. If the pain and swelling does not dissipate within three to four days, call your doctor and tell them about your symptoms.

Summary:
Pluck the ingrown hair when you're able to. Treat the irritated skin. Get antibiotics.
