Tanning is mainly a natural result of prolonged exposure to the harmful UV rays of the sun which can affect the normal functioning of the skin cells and can also lead to multiple skin disorders. It is this reason why the skin cells start producing too much melanin. It is a countermeasure to repel this harmful effect. Melanin is a dark brown or black colour pigment that gives colour to our skin and hair.
This buildup of melanin in the skin due to overexposure also leads to darker skin tone.

How to de-tan skin?

Skincare experts recommend not opting for artificial ways of tanning such as chemical sprays, lamps, and tanning beds which can cause harm to one’s skin. Thus, you can get the best de-tan skin results at home by doing these remedies with detailed steps.
Turmeric, honey, and milk

Turmeric has high antioxidant properties that help lighten depigmentation or dark spots. Milk also has skin-brightening properties that can also help reverse the effects of UV rays. When mixed and applied on the skin, it gives an even brighter tone.

How to make it: Take ½ tablespoon of turmeric powder and two tablespoons of milk and honey, and make a thick paste. Apply the mixture equally on the areas most affected by sun rays, and let it dry. Rinse it off and pat dry the skin.
