Five mistakes and how to fix them when using sunscreen

Dark skin and acne after using sunscreen is not necessarily due to poor quality products, but may be because you are not using it correctly.

Applying sunscreen is an indispensable step to protect the skin from UV rays - the agent that causes premature aging, melasma, dark spots and even skin cancer. However, many people complain that, despite using adequate sunscreen, their skin is still dark, prone to acne and dull.

According to dermatologists, the cause lies in seemingly harmless mistakes that silently destroy the skin's protective barrier, causing premature skin aging.

Choosing the wrong sunscreen

Not all products are suitable for all skin types. People with oily or acne-prone skin should use sunscreens containing mineral oil, thick silicones or fragrances, which can easily clog pores and cause acne.

Dr. Shari Marchbein, a dermatologist in New York (USA), recommends choosing sunscreen that is oil-free, non-comedogenic, and has a light texture, especially in tropical climates like Vietnam.

Applying insufficient amount of cream

Many people only use a small amount of the product because they are afraid of clogging their skin or to be frugal. In fact, to achieve the protection as stated in the SPF on the packaging, you need to apply about 2mg of sunscreen per square centimeter of skin, equivalent to 1/4 teaspoon for the face.

If you use less, your skin will not be properly protected, leading to dark spots, melasma, and even sunburn.

Do not reapply cream every 2-3 hours

Under the influence of sweat, oil and harsh sunlight, the initial layer of cream will wear away, reducing the protective effect. A study published in the Journal of the American Academy of Dermatology showed that UV protection is reduced by up to 50% after only 2 hours if not reapplied.

Dermatologist Sandra Lee (Dr. Pimple Popper) also emphasizes: "If you are outdoors, set a reminder to reapply sunscreen at least every 2 hours."

Do not apply sunscreen to the skin around the eyes and lips.

The habit of ignoring the skin around the eyes and lips is also the reason for uneven skin tone. These are sensitive, fragile areas and are very susceptible to darkening and wrinkles if not properly protected.

Many people are afraid that sunscreen will sting their eyes, but in fact, mineral sunscreens (physical sunscreens) with zinc oxide and titanium dioxide are safe, gentle choices for the eye area.

Not protecting skin from the sun

A serious but often overlooked mistake is using sunscreen as the “only shield” against the sun. In fact, no product provides 100% protection against UV rays.

Sunscreen is just one part of a comprehensive sun protection strategy that also includes wearing a wide-brimmed hat, sunglasses, sun-protective clothing, and avoiding the sun during peak hours (10am-4pm).
