Which Fitzpatrick skin type is MOST likely to tan and LEAST likely to burn?

• A. Type I
• B. Type IV
• C. Type II
• D. Type III

Answer: (B)

Sun exposure tolerance depends on melanin, which acts as a natural shield against UV rays. The more melanin in the skin, the more likely the skin is to tan rather than burn. Fitzpatrick type IV has a relatively higher level of melanin, so individuals with this type tend to tan easily and burn only minimally. They still can burn with intense or prolonged sun exposure, but compared with lighter skin types, burning is less likely and tanning occurs more readily. In contrast, lighter types burn quickly and tan poorly or gradually, which is why they don’t fit the description of someone who tanS readily and burns least. So the person most likely to tan and least likely to burn is Fitzpatrick type IV.
