There are many myths about SPF products, and in order to know exactly how to use sunscreen to prevent the harmful effects of ultraviolet rays, it is important to understand the most common misconceptions.
Myth No. 1: SPF application in the morning will protect you throughout the day
Apply SPF before going out into the street is the right step, but to believe that this is enough for the whole day is wrong. Sunscous cream loses its effectiveness when exposed to light and is gradually destroyed. It is best to update it every 2 hours, and if you are not under the straight sun – every 4 hours.
Myth No. 2: Most of the sunscreen waterproof creams
Even if the package indicates that the cream is waterproof, this is not so. In fact, such products do not exist. The most powerful sunscreens withstands water exposure to only 40-80 minutes. Therefore, especially on vacation, it is necessary to regularly update the layer of cream after bathing and sweating.
Myth No. 3: SPF in your moisturizing cream or makeup enough to protect
SPF moisturizer is a good addition, but it will not replace full protection. Dermatologists recommend using individual products with a minimum of SPF 30. To apply the product in the right amount to the body, it will take about 30 grams (approximately a glass), and a teaspoon on the face and neck.
Myth No. 4: Sunscreen cream should only be used in the summer
Many believe that sunscreen is needed only in the summer, but this is not so. Rays UVA and UVB are dangerous all year round. In winter, snow and ice can reflect up to 90% ultraviolet rays, increasing the risk of burns. Even in cloudy weather, ultraviolet can harm your skin, reports Yon-KA.RU (18+).
Myth No. 5: the darker the skin color, the less need SPF
SPF needs everyone, regardless of skin color. The dark shade of the skin is less susceptible to burns, but ultraviolet rays still harm. Daily use of SPF 15 can reduce the risk of skin cancer by 40% and melanoma by 50%, and also prevents premature skin aging.
Myth No. 6: You do not need to reuse with a high SPF tool as often as with low SPF
Sunscreen with a higher SPF really provides better protection, but it does not extend the validity of the product. Regardless of SPF, the cream should be applied every 2 hours, as well as after bathing and sweating.
Myth No. 7: Sunscreen has no expiration date
This is wrong. Like any other cosmetic agent, the active ingredients of the sunscreen can collapse over time. Always check the label. If it is not, then count three years from the moment of purchase of the product. To obtain a sufficient dose of vitamin D, dermatologists recommend spending only 5-30 minutes a day in the sun. The rest of the time is important to protect the skin with the SPF 50 cream, which also supports the epidermis water balance and helps to fight oxidative stress and photographs of the skin.
These SPF myths often mislead people. Knowing the truth, you can better protect your skin and maintain its health and beauty for many years.
