Which skin type is most likely to see effects after the least amount of tanning sessions?

Skin Type I is characterized by very light skin that always burns and rarely tans. This type has minimal melanin production, which means it offers less natural protection against UV radiation. As a result, individuals with Skin Type I are more susceptible to the harmful effects of tanning, such as burning and skin damage, even after just a few sessions.

Since this skin type does not have the pigmentation that provides some degree of protection against UV rays, effects are noticed quickly, including redness and irritation. Consequently, people with Skin Type I should be particularly cautious and aware of their tanning exposure, as they can easily experience adverse reactions from minimal UV exposure.

In contrast, the other skin types (II, III, and IV) have more melanin, which provides a greater level of protection and allows for a more gradual tanning process, requiring more sessions to see notable results.
