No, going to the gym does not directly help in skin whitening.
While exercise is beneficial for overall health and well-being, it does not impact skin pigmentation. Skin color is determined by the amount of melanin produced by melanocytes, which are cells in the skin.
Exercise can improve blood circulation, which may give your skin a temporary healthy glow. However, this is not the same as skin whitening.
If you are interested in lightening your skin tone, it is important to consult with a dermatologist. They can recommend safe and effective treatments that are tailored to your individual needs.
