Sunscreen…common mistakes and tips for effective protection

As summer temperatures rise, using sunscreen becomes an essential part of your skincare routine, not just a product used when going to the beach. Daily exposure to ultraviolet rays may lead to pigmentation, premature wrinkles, loss of skin elasticity, and increases the risk of skin cancer.

Despite increasing awareness of the importance of sunscreen, there are still questions about how to use it, the meaning of protection factor (SPF), and how to choose the appropriate product for each skin type. Here is the most important information you should know.

Why should you use sunscreen daily?

UV rays are not limited to sunny days, they penetrate clouds and glass, which means that the skin is exposed to them while driving, walking, or even sitting near windows. Therefore, dermatologists recommend using sunscreen daily throughout the year.

What is the difference between UVA and UVB rays?

• UVA: Penetrates into the deep layers of the skin, causes premature aging, wrinkles, and pigmentation, and is present throughout the year.

• UVB: affects the surface layers, causes sunburn, and increases in severity during the summer, and is also linked to an increased risk of skin cancer.

Therefore, it is preferable to choose a condom that provides broad spectrum protection against both types.

What does SPF mean?

Sun protection factor (SPF) refers to a product’s ability to protect against UVB rays. The higher the number, the greater the percentage of protection, but the difference between the degrees is not as large as some think.

• SPF 15 blocks about 93% of rays.

• SPF 30 blocks about 97%.

• SPF 50 blocks about 98%.

• SPF 100 blocks about 99%.

Experts confirm that correct use and reapplication is more important than choosing the highest SPF number.

What is the right amount?

Experts advise using the two-finger rule, that is, applying an amount extending along the index and middle fingers to cover the face and neck. The body needs about 30 ml of condom to ensure complete coverage.

When is it used?

It is preferable to apply sunscreen 15 to 20 minutes before exposure to the sun, while mineral sunscreen can be used immediately before going out, making sure to distribute it well.

When should it be reapplied?

• Every two hours when exposed to the sun.

• After swimming.

• After heavy sweating.

• After drying the skin with a towel.

Is makeup that contains SPF enough?

No, because the amount of makeup used usually does not provide the level of protection written on the package, so sunscreen must be applied first and then makeup.

Should it be used indoors?

If you spend a lot of time near windows, while driving, or in front of light sources for long periods, it is best to continue using it to protect against pigmentation and premature aging.

Chemical or mineral condom?

• Chemical protectant: absorbs ultraviolet rays, has a light texture and does not leave a white residue.

• Mineral sunscreen: Often contains zinc oxide or titanium dioxide, reflects rays away from the skin, and is suitable for sensitive skin.

How to choose the right sunscreen?

• For oily skin: oil-free formulas with gel or fluid textures.

• For dry skin: Products containing moisturizing ingredients such as hyaluronic acid and ceramides.

• For sensitive skin: Mineral sunscreens that are fragrance- and alcohol-free.

• For acne-prone skin: Products bearing the phrase Oil Free andNon-comedogenic.

Does dark skin need sunscreen?

Yes, melanin gives dark skin only partial protection, but it does not prevent pigmentation, premature aging, or the risk of skin cancer, so it is recommended to use sunscreen for all skin colors.

Does sunscreen prevent vitamin D production?

Studies indicate that the normal use of sunscreen does not prevent the body from producing vitamin D completely, and any deficiency can be compensated for through food or nutritional supplements when needed.

Do children need sunscreen?

It is recommended to use a sunscreen intended for children over six months of age, while it is best to protect younger infants with shade and protective clothing and avoid direct exposure to sunlight.

Does sunscreen expire?

Yes, as it loses its effectiveness after the expiration date or when exposed to high temperatures for long periods.

Common mistakes that reduce its effectiveness

• Use a small amount.

• Forget about the neck, ears and back of the hands.

• Do not re-apply.

• Using an expired product.

• Relying on makeup alone.

• Believing that dark skin does not need protection.

Does it replace other means of protection?

No, the best skin protection remains to be based on a combination of sunscreen and wearing hats, sunglasses, and protective clothing, while avoiding direct exposure to the sun between the hours of ten in the morning and four in the afternoon and staying in the shade as much as possible.

Dermatologists confirm that daily and correct use of sunscreen is one of the most important steps to maintain healthy skin and limit the effects of exposure to ultraviolet rays in the long term.
