In-growing facial hairs are often caused by incorrect shaving.
Rule number 1 when having a wet shave: never shave against the direction of hair growth! If you shave in all directions, this quickly pulls the facial hair out, causing unnecessary stress for the skin and possibly inflammation. Very horny skin can make it even more difficult for facial hair to grow out – the hairs remain underneath the surface and grow inwards.
Tip: Regular exfoliation removes dead skin cells. Last but not least, if your skin is particularly bad, this can distort the hair follicles and sometimes the direction of hair growth, which can lead to hair growing along under the skin. In-growing facial hair can often be removed using tweezers (carefully!) – but only when a red circle has not yet formed around the hair. If this is the case, consult a dermatologist.
