Detailed answer

While body lotion can provide hydration and some nourishing ingredients that may help in fading sunspots on the knees, it is important to note that sunspots are caused by excessive sun exposure and can be resistant to treatment. Body lotions with ingredients like vitamin C, niacinamide, retinol, or hydroquinone may offer some benefits in reducing the appearance of sunspots. However, for more stubborn sunspots, it's recommended to consult a dermatologist who may suggest alternative treatments like laser therapy, chemical peels, or cryotherapy. Additionally, protecting your skin from further sun damage by using sunscreen with a minimum SPF of 30 and covering your knees with clothing when exposed to the sun is crucial in preventing the formation of new sunspots.
