People who have to say 'no' to sunscreen

Sunscreen is the most "unseen thing" of women because it not only helps skin avoid darkening but also prevents cancer. However, not everyone can use this cream.

Sunscreen as a shield, helps protect skin from sun damage - the cause of melasma, tanning and especially dangerous skin cancer risk.

According to research in the Annals of Internal Medicine, people who use sunscreen daily have skin that looks much younger. SPF 15 or higher sunscreen prevents 93% of UVB ultraviolet rays and also filters out UVA rays. In addition to being the culprit for skin cancer, UVB and UVA rays also cause skin aging.

Scientists at the Queensland University of Technology have studied the impact of sunscreen on skin cancer prevention.

Scientists have tested that sunscreen is able to protect a gene called P53 . Genes against three types of skin cancer are basal cell carcinoma, keratocellular cancer and melanoma cell cancer.

Elke Hacker, the lead researcher, said that when a region of the skin is affected by sunlight, the P53 gene will immediately move there and heal the damaged skin, while not allowing the cell. Cancer formed.

Therefore, without the protection of sunscreen when the skin is constantly exposed to sunlight, the P53 genes will be altered to facilitate cancer cells to form and develop.
