Vitamin B6 has a certain effect on whitening and spot removal, but it mainly plays a supplementary role. If you want to whiten and lighten the spots, you can rely on medical cosmetic technology, such as laser cosmetic spot removal, photon spot removal, liquid ammonia spray freezing treatment method, whitening injection and fruit acid peeling methods. Vitamin B6 can promote the absorption of amino acids and protein synthesis to ensure the nutrition of cell growth, as well as inhibit sebum secretion, which is useful for the treatment of some skin dermatitis and acne. In addition, vitamin B6 can also synthesize the hormones that get rid of dark spots, and therefore, can play a certain role in whitening. If the lack of vitamin B6 is clearly diagnosed as the cause of dry skin, dull yellow, poor skin elasticity, etc., vitamin B6 can be taken in appropriate amounts under the guidance of a doctor to treat and regulate the state of the skin. However, it is worth noting that excessive amounts of vitamin B6 should not be used to avoid neurotoxicity and photosensitivity reactions, such as progressive gait instability, numbness of the feet and inflexibility of the hands, which can usually be relieved after stopping the medication. In addition to medical cosmetic techniques to help whiten and remove spots, daily attention to sun protection is also needed to avoid UV radiation damage to the skin.
