After what time red skin goes brown after sunbathing?

After sunbathing, red skin typically begins to turn brown within a few days as the skin undergoes a healing process and melanin production increases. The exact timing can vary based on skin type, the intensity of sun exposure, and individual healing responses. Generally, it may take anywhere from 3 to 7 days for redness to fade and for a tan to develop. It's important to note that excessive sun exposure can lead to skin damage, so proper sun protection is essential.
