It may not be possible to wear foundation on the neck wound for six months after thyroid surgery, but this will depend on the recovery of the wound. After thyroid surgery, there will be obvious wounds on the neck and the damaged skin tissues need some time to recover. If the local wound has recovered well after six months of surgery, and there is no scarring, inflammation or infection, you can wear foundation after six months. If there is obvious scar growth or inflammation and infection after the surgery, resulting in the wound not healing for a long time, it is not recommended to use foundation after six months. This is because foundation contains chemicals that can cause damage to the skin tissue if used for a long time, and you need to use make-up water or make-up oil to clean up after using foundation, and using cleansing products for many times will not be conducive to the recovery of the damaged tissues. For more information about medical care after thyroid surgery, please consult a professional physician or nurse practitioner.
