Sunscreen – the indomitable object on a hot summer day
As one of the indispensable products on a summer day, sunscreen helps people protect the skin, avoiding the effects of ultraviolet (UV) rays in the sun. Ultraviolet rays are divided into 3 types, UVA, UVB, and UVC rays. In which, UVA, UVB rays can pass through ozone layer and harm human health; UVC rays are blocked by the ozone layer, unable to penetrate the ground. Therefore, when going outdoors, our skin will be affected by UVA and UVB rays, which darken the skin, damage the skin, accelerate the aging process and increase the risk of skin cancer.
Sunscreen helps people protect the skin from the effects of ultraviolet (UV) rays in the sun.
To protect the skin from the effects of UV rays, consumers who choose sun protection products, including sunscreens, should pay attention to choosing a cream with a higher SPF number, which protects the skin from UV rays. higher. For example, SPF 2, skin protection ability is 50%; SPF 15, skin protection ability is 94%; SPF number is 100, the ability to protect the skin is 99%. However, consumers should not choose products with the SPF number too high, as it can cause skin irritation. Therefore, consumers only need to choose at 30, 50 for the best.
Besides, when buying a sunscreen, consumers also pay attention to the PA index (denoted PA ++, +++…) on the sunscreen. The more + sign, the better the resistance to UV rays.
However, consumers also note, it is possible that the sunscreen is suitable for one person, but irritates the skin for another. So, consider before choosing this skin protection product.
Experts warn against the harmful effects of sunscreen if used in the wrong way
Recently, the US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection. Two safe and effective ingredients in sunscreen are zinc oxide, titanium dioxide. Meanwhile, the ingredients aminobenzoic acid (PABA) and trolamine salicylate have been warned by the FDA to be unsafe.
FDA also requires manufacturers to demonstrate the safety of 12 sunscreen ingredients: cinoxate, dioxybenzone, oblulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone. Therefore, consumers need to pay close attention to the ingredients on the product label when choosing sunscreen.

To prevent skin cancer, Associate Professor, Dr. William W. Huang, Wake Forest School of Medicine, recommends applying sunscreen about 30 minutes before going out in the sun and reapplying at least every two hours. Facial skin is a sensitive, vulnerable place to ultraviolet rays leading to skin cancer, so priority is given to applying cream on the face.
Ohio-based dermatologist Amy Kassouf also noted that sunscreen should be applied to small areas of skin like the eyelids, lips, and ears. Most lip cosmetics do not contain SPF. The skin on the edges of clothing is also often sunburned, so more sunscreen should be applied, according to dermatologist Jennifer Stein in New York. People with sensitive skin should use sunscreens containing zinc oxide and titanium dioxide in place of the chemical sunscreen ingredient.
According to chemist and founder of the beauty website The Beauty Brain – Perry Romanowski, expired sunscreens will no longer be able to protect your delicate skin. At this time, sunscreen, whether physical or chemical, has no longer reached the SPF level as advertised. Meanwhile, chemical sunscreens with ingredients containing oxybenzone, avobenzone and homosalate can oxidize and become less effective. Physical sunscreens contain zinc oxide or titanium dioxide, although there is no oxidation, they still lose the quality and effectiveness of sun protection. Simply put: while the sunscreen ingredients are active, they may not be able to function properly in skin protection.
Also sharing about the harmful effects of sunscreen, Dr. Erin Gilbert said that when you open the bottle of sunscreen with dirty hands, or open too many times can cause bacteria to enter the product. Decreases the quality of the cream and causes acne breakouts when used.
Dr. Gilbert recommends that if you leave sunscreen in a hot place such as in a car, swimming pool or in a bag, it will expire more quickly due to high temperature environments. In this case, you should replace it every few months to ensure that the sunscreen will always work effectively.
