Factors such as age, health, and skin type all determine how an individual will be affected by UV exposure.
People over the age of 50 and under the age of 5 are generally more sensitive to the harmful effects of UV. Those with immune deficiencies and chronic diseases also tend to be more susceptible to the side-effects of UV exposure.
In general, people with medium to dark complexions are less sensitive to UV exposure. Although people with darker complexions are less likely to get skin cancer than people with lighter complexions, they can still develop malignancies and suffer all forms of UV damage.
Dermatologists divide human skin into six types. Type I is the most sensitive and type VI is the least sensitive. People with skin type I are at a particularly high risk and should try to avoid exposure to UV.
People who need to be especially careful in the sun are those who have:
- Pale skin
- Blonde, red, or light brown hair
- Been treated for skin cancer
- A family member who’s had skin cancer
Certain oral and topical medicines, such as antibiotics, birth control pills, and benzoyl peroxide products, as well as some cosmetics, may increase skin and eye sensitivity to UV in all skin types. Check the label and ask your doctor for more information.
