Have you ever felt strange, exaggerated skin burning or any abnormal changes in your skin in the sun? These symptoms may be caused by photosensitizing chemicals in drugs or cosmetics that produce a biological response when exposed to ultraviolet rays. This type of ultraviolet light may come from the sun or other types of artificial ultraviolet light, such as the “purple light” mosquito killer, which usually does not cause problems.
Photosensitizers can cause two basic types of reactions: photoallergy and phototoxicity.
It is not clear why there is a photoallergic reaction in the body. Ultraviolet rays cause skin reactions to chemicals that have been applied to the skin, such as sunscreens, perfumes, cosmetic or antibiotic ointments, or ingested drugs. It usually causes an allergic reaction in the body in the form of a rash, small blisters or other types of rash. Symptoms usually appear 24 to 48 hours after being exposed to the sun, but may also appear within 20 seconds of UV exposure. Sometimes, photoallergic reactions can be delayed by up to 3 months. And this allergic reaction can spread to other parts of the body that never exposed to the sun.
Phototoxic reactions are more common than photoallergic reactions, but it does not affect the body’s immune system.
In phototoxic reactions, photoreactive components absorb energy from ultraviolet light (usually UVA) and release it into the skin, causing skin cells to damage or die within a few minutes to up to several hours after UV exposure. However, the damaged skin is limited to those parts of the body that are exposed to the sun.
You may be worried about getting photosensitivity. Some people may ask whether the sunscreen can help protect them against it. The answer is not quite sure. Actually, the sunscreen will reduce the amount of UV radiations that reflect your exposed skin. But some sunscreens have ingredients that may cause photosensitivity to some extent. Therefore, the best, easiest and cheapest way to protect you from the sun and its harmful UV rays is to wear a good sun hat. It will not damage your skin or cause phototoxic reaction. If you have sensitive skin, you may not apply much more sunscreen that may cause hypersensitive response. A sun hat is safe solution to your sensitive skin protection.
You need to think about what you want it do when choosing a sun hat. There are many kinds of sun hats in the market. For example, baseball caps, bucket hats, straw hats and so on. Different types of sun hats may have different degree of sun protection ability. Bucket hats are often worn by many stars, hipsters and hip-hop musicians. And it not only performs well in sun protection but it also as a decoration to people’s outfits. The bucket hat comes in different styles, such as solid colors, floral patterns and letter patterns. Most bucket hats are made of lightweight, soft and durable materials, like cotton, nylon and denim. It can be worn all year round. With wide brim can protect your face, eras and neck from being exposed to the sun. A bucket hat can be used for your hiking, fishing, camping, backpacking and more.
