However, excessive exposure can lead to skin damage, accelerate skin aging, and increase the risk of cancer. Using suitable sun protection is essential to prevent the harmful effects of UV rays.

Can azelaic acid be used in the morning, before sun exposure?

Some topical agents, particularly those used in acne treatment, can make the skin more sensitive to the sun, meaning it is more likely to burn even if this is not typically the case. Let's examine here whether this is true for azelaic acid to determine if it can be safely used during the day or if special precautions need to be taken.

FAQ about uv light

What are the different types of UV rays?

There are three types of UV rays: UVA, which are responsible for skin aging, UVB, which cause sunburn, and UVC, which are blocked by the Earth's atmosphere.

How to protect oneself from UV rays?

To protect oneself from UV rays, it is advised to wear broad-spectrum sunscreen, protective clothing, a hat, and sunglasses, and to avoid the sunniest hours of the day.

Do clouds block UV light?

No, up to 80% of UV rays can penetrate through clouds, which is why it's crucial to protect yourself even on cloudy days.

Are children more vulnerable to UV rays?

Yes, children's skin is more sensitive to UV rays which makes them more susceptible to sunburns and long-term damage.

Do windows block UV rays?

House or car windows block the majority of UVB rays, but allow a significant portion of UVA rays to pass through, hence the importance of wearing sun protection, even indoors.

Does UV light exclusively cause skin cancer?

UV rays are primarily responsible for skin cancers, but they can also damage the eyes and increase the risk of cataracts.

Does tanning protect against UV rays?

Tanning is primarily a skin defense reaction against the damage caused by UV rays. It does not protect against the long-term effects of ultraviolet radiation.

Is the sun beneficial for acne?

While the sun may temporarily improve acne, prolonged exposure often exacerbates inflammation and promotes the development of scars.

What are the risks of prolonged sun exposure?

Extended and/or repeated exposure to the sun can lead to sunburn, premature skin aging, pigmentation spots, and an increased risk of skin cancers.

Can sun exposure trigger allergies?

Yes, some individuals develop reactions such as summer light eruption or phototoxic rashes following sun exposure.
