Dangers of sunscreen use

Creams and other products with skin-protection role against harmful UV rays of the sun are those that filters ultraviolet rays when applied to the skin.

They absorb some UV rays to protect skin and prevent burns or conditions caused by sun exposure, such as melanoma.

It is important to protect skin of UV rays, especially if you have a colored or sensitive skin. However, there are some dangers associated with use of the products with filtering role against sunlight.

Chemical controversy

Some types of sunscreen- role products contain chemicals that can be harmful to the body.

Biochemists say the ingredients that are found in the composition of sunscreen products, can act like estrogen and can determine some confusions through chemical messages in the body.

Other researchers argue that some sunscreen chemicals are actually toxic to humans, actually can be carcinogenic.

However it is important to understand that these statements have not been tested enough and many sunscreen products can be used safely. If however you are concerned about certain chemical reaction, you should ask your doctor.

Vitamin D deficiency

Vitamin D is an important chemical compound for humans. This helps maintain the stability level of blood calcium and phosphorus, calcium absorption and helps protect against osteoporosis and hypertension.

Some studies have shown that vitamin D may provide protection for certain types of cancer and autoimmune diseases. Vitamin D can be assimilated from different types of foods and vitamin supplements, but is most easily absorbed by exposure to UV rays. Sunscreens prevent the adequate levels of vitamin D absorption.


Some people with sensitive skin who have allergies or asthma may react negatively to the additives in the products that offer UV protection. In some cases of asthma, fragrances can be irritating. If you suffer of asthma, opt for creams that contain no dyes, fragrances and preservatives.

Sun protection

After some studies have shown that there are enough people excessively using UV blocking products, without taking into account other sun protection methods (such as for example clothes or avoid spending time outdoors in the middle day when the sun’s rays are strongest).

However, the role of sunscreen creams, even if they can give people a sense of protection, is not sufficient, especially in people who spend time in the sun and do not use products with an appropriate SPF or not applied often enough as should be.

Can’t set yet a clear relationship between melanoma incidence and use sunscreen products, but this is further investigated.
