The least harmful burn is the first-degree burn, also called superficial skin burn. This burn makes your skin red, dry, and painful when you touch it. This is the most common type of sunburn and can heal within 3 to 6 days.
The second-degree type of burn, also called superficial partial-thickness burn, effects the top two layers of your skin. It will hurt if the temperature changes or if you touch it. You may see blisters appear on your burn, which hold leak fluid. This type of sunburn will heal in 7 to 21 days and the color of the original skin may be lighter or darker. You might develop a scar with this type of burn.
The third-degree burn, also called deep partial-thickness burn, is deeper than the second-degree burn and is more severe. This burn will most definitely give you blisters and takes even longer to heal. This burn will give you a scar if it doesn’t heal by the 21st day.
The last type of burn is very serious and to be avoided at all costs. This is the fourth-degree burn, also called full-thickness burn, and it would be treated like a surgery. It affects all the layers of skin and possibly the fat and muscle underneath as well. This burn makes the skin turn a different color, normally white, grey, or black! You could end up in the hospital for days taking medications. To say this would put a damper on your vacation would be an understatement – this type of burn can cause severe long term damage to your skin.
Sunburn damage may cause different types of sunburn ranging from very mild redness to excruciating vast burn with blistering but rarely reaches the deep-partial thickness type of burn.
