Recovery time after sunburn on the face depends on the degree of sunburn, usually it takes 3~4 days for short cases and may take 3~4 weeks for long cases. If the sunburn is only mild, the sunburned area is painful, erythema, mild edema, usually the tingling sensation of the skin lasts for 3 to 4 days, then the cells of the basal layer of the skin begin to repair the damage, the sunburned area will slowly fade until it is replaced by new skin, this process usually takes 1 to 2 weeks. If the skin is heavily sunburned, with blisters or even vesicles, the recovery time is much longer and may take 3 to 4 weeks, and in the case of concurrent skin infections, the recovery takes even longer. If repeated mild sunburn, it will lead to skin pigmentation, which is often referred to as tanning, this situation requires a longer recovery time, it may take about half a year. Normally, you need to protect your skin from the sun, and if you have a sunburn, you should seek medical attention in a timely manner.
