Which skin type is most likely to experience immediate tanning response?

Skin type 5 is most likely to experience an immediate tanning response due to its characteristics, which include a higher level of melanin production. Individuals with this skin type usually have a medium brown skin tone and are less likely to burn when exposed to UV light. This intrinsic pigment offers a baseline of protection and allows for a faster tanning process when compared to skin types with less melanin.

In contrast, skin types 2 and 3, which have lighter skin tones, tend to have a slower tanning response and are more vulnerable to sunburns. Their reduced melanin levels mean that it takes longer for these skin types to develop a tan, as they require more UV exposure to stimulate melanin production.

Skin type 6 has even more melanin than type 5, typically presenting as very dark brown or black skin. While individuals with skin type 6 can tan well and maintain pigmentation, they usually experience a more gradual tanning response compared to those with skin type 5, who can achieve a more immediate tan due to their already elevated baseline melanin levels.
