The monsoon season is over and summer is in full swing. After doing outdoor activities under the hot sunlight, the skin becomes red and it is easy to suffer from sunburn (sunburn), which is stinging and burning.
In particular, excessive exposure to UV rays can cause not only sunburn but also skin cancer, so it is best to avoid it as much as possible.
According to the medical community on the 29th, ultraviolet rays are known to be the most important cause of skin aging and pigmentation disorders. UV exposure promotes the breakdown of collagen in the skin and stimulates melanocytes that produce pigment, exacerbating pigment diseases such as freckles.
It is easy to understand if you think of the old man who worked outdoors a lot when he was young, not only full of small wrinkles, but also full of age spots or black spots.
If there are only wrinkles or age spots, it can be said that it is fortunate in terms of health. However, chronic UV exposure increases the risk of skin cancers such as squamous cell carcinoma and basal cell carcinoma.
Professor Kwon Soon-hyo of the Department of Dermatology at Kyunghee University Gangdong Hospital said, “Exposure to ultraviolet rays induces mutations in keratinocytes in the skin, leading to skin cancer.” It is good to expose your arms and legs to sunlight, except for the face, which is an area where skin cancer is most likely to occur.”

It is best to choose a sunscreen that can block both UV A and B UV. The first index to check when choosing a sunscreen is SPF, which indicates the degree to which the skin is protected from UVB. PA is the blocking index for UV A and is expressed as +/++/+++ depending on the degree.
SPF15 blocks 94%, SPF30 blocks 97%, and SPF50 blocks 98%. If you look at the blocking rate alone, it would be good to apply SPF50, but once applied, the sunscreen is washed away little by little under the influence of sweat, so it is important to apply a sufficient amount and reapply frequently even if you choose a high SPF one.
In general, apply it 30 minutes before going out and apply a sufficient amount thoroughly every 2-3 hours. It is also effective to apply an amount of 1.0mg/cm2, which is half the recommended amount, twice.
In particular, different types of sunscreen should be selected for each type of skin. For ‘sensitive skin’, it is recommended to use a physical blocker that does not contain chemical blockers, hypoallergenic products, fragrance-free, and allergy-free products as much as possible.
For ‘dry skin’, a cream type sunscreen is better and a waterproof type with excellent moisturizing power is better, and for ‘oily skin’, an essence or lotion type sunscreen with less oil is better. Chemical sunscreens can make acne worse, so it’s a good idea to choose the right mix of chemical and physical sunscreens.
Ideally, sunscreen should be easy to spread evenly and remain on the skin surface without washing off or dripping following application. It is necessary to consider how wide the area will be applied, how evenly it will be applied due to wrinkled hair, and whether it will not be easily washed off with sweat or water.
A cream type is better than a water-soluble type that is easily removed by sweat, and if you mix it with a cream or oil to improve the spreadability, the blocking effect will decrease.

In addition, the younger you are, the more vulnerable you are to UV damage and the more likely you are to get sunburned, so it is important to reduce your exposure to UV rays and use sunscreen.
Professor Kwon said, “Children have thin skin and a large surface area compared to their body weight, so the amount absorbed is relatively high, so the possibility of systemic side effects is higher. It is recommended to avoid UV rays and to use sunscreen only if it is more than 6 months old.”
He continued, “From 6 months to 2 years of age, it is recommended to use a sunscreen made of only physical blocking ingredients that have low absorption and are less likely to cause side effects such as skin irritation and allergies. product is preferred. It is better to apply it avoiding the area around the eyes and use a water-resistant product.”
