Obsession with removing tan instead of UV protection
I am not sure if this is relevant but after seeing possibly the 100th post on how to remove tan, I think people don't understand what removing tanning actually means.
A tan fades through skin cell turnover, your skin naturally sheds the UV-exposed cells over time. So when you are looking for ways to get rid of tanning, you're looking for ways to remove the upper most layer of your skin.
Most tan removal methods are just ways to speed up that process through exfoliation or chemicals. That can help, but doing it too aggressively or trying every totka will only irritate your skin.
Focus more on protecting your skin from UV damage instead of obsessing over removing tan. Be gentle with your skin and let natural turnover do its job. UV exposed skin is more prone to dryness so focus on moisturizing.
And honestly, it’s just a tan, maybe question why darker skin is treated like something undesirable in the first place.
