TEA TREE OIL Side Effects & Safety. Tea tree oil is POSSIBLY SAFE for most people when put on the skin, but it can cause skin irritation and swelling. In people with acne, it can sometimes cause skin dryness, itching, stinging, burning, and redness.
Baby acne is a very common skin rash which usually develops in the first few weeks after birth. It is more common in boy babies than girl babies. This rash confuses many parents who assume (and not unreasonably) that acne is something which affects adults, especially teenagers.
In most cases, baby acne will go away on its own within three weeks to three months. If after three months the baby acne shows no signs of improvement, parents should point out the acne at their child's wellness visit to see if there is an underlying skin condition that needs to be addressed.
