【Laiwo Medical: Knowledge Sharing】In summer, there is something more annoying than getting tanned
Publish Date: 2026/6/8
I don't know if you have noticed a very strange skin phenomenon: acne that grows in winter and spring seasons, the red marks left after fading, do not need to be deliberately treated, and will gradually fade and disappear after a period of time. But the acne scars that appear in summer or the old scars left over from winter and spring, which have lasted for more than half a year without fading, continue to deepen and even turn black in summer.
Many people subconsciously doubt themselves when they encounter this situation: can't they resist touching their face and getting pimples? Or is it due to poor skin quality or weak metabolic capacity? In fact, most of the time, the problem is not your skincare habits or skin condition, the real culprit is because the seasons have changed.
In summer, giving acne scars a 'privilege'
After acne subsides, the skin is actually in a fragile, semi healed state, more susceptible to external stimuli than normal skin. And the excitement of summer is exactly the most. The two biggest 'enemies' will appear simultaneously in summer:
Firstly, ultraviolet radiation
It is the primary driver of pigmentation. After skin damage, melanocytes are "activated" and automatically run to the injured area to "work" in an attempt to protect the skin - this is the main reason why acne scars turn black. In winter, you get less sunlight, so melanin can still be lazy; In the summer, when you step out a little bit, the ultraviolet rays will repeatedly urge that acne mark: "Hurry up and color it
Secondly, sweat
Many people are unaware that sweat is not friendly to damaged skin. It contains ingredients such as salt, urea, lactic acid, etc. If left on the skin after acne has just disappeared for a long time, it can create a stimulating microenvironment that prolongs the inflammatory response. If inflammation does not subside, melanin will continue to work. So before the red acne mark left, the black acne mark was already on its way. What's even more troublesome is that in summer, you keep sweating, and repeatedly wiping sweat is also a burden on newly repaired skin.
Do two things well, don't let acne marks linger on your face
Sunscreen is a prerequisite for repair
If you don't protect yourself from the sun, it's difficult to apply anything afterwards because UV rays keep melanin "working". It is recommended that everyone try to provide physical shelter when going out: hats, masks, umbrellas, sunglasses can all be arranged. If applying sunscreen, choose gentle and non irritating products. In short, preventing ultraviolet rays from touching acne scars is an effective way to lighten them.
Clean promptly and gently after sweating
After sweating, gently wash with water or use a clean tissue or cotton cloth to press and dry, especially in the area where acne scars are located. Do not let sweat dry naturally. This is not for the ritual of skincare, but to shorten the irritation time of sweat on damaged skin.
Laiwo Medical Warm Reminder: The deepening of acne scars in summer is not necessarily a signal of skin deterioration, but may also be a normal reaction brought about by the season and environment. There is no need to be overly anxious, nor to blindly follow the trend and use various light printing products. As long as you do a good job of sun protection and timely cleaning, give the skin some time and a quiet environment, it will naturally fade away. But if acne scars continue to worsen and there is no sign of improvement for a long time, it is necessary to promptly seek targeted treatment from a dermatologist.
