Detailed answer

Hand creams that contain certain ingredients like niacinamide, vitamin C, alpha hydroxy acids (AHAs), or kojic acid can be beneficial in reducing hand discoloration caused by sun exposure or pigmentation disorders. These ingredients help to brighten the skin and fade dark spots gradually. However, it is important to note that hand creams alone may not provide significant results, and consistent use of sunscreen is essential to prevent further sun damage. Additionally, if the discoloration is severe or persistent, it is advisable to consult with a dermatologist for a personalized treatment plan.
