Common conclusions
You should start using sunscreen because it can help keep them from getting darker and it can also prevent new dark spots from forming. You should protect your skin from the sun all year long and if your legs will be exposed use a broad-spectrum sunscreen with an SPF of 30 or higher.
Cryotherapy is a procedure in which liquid nitrogen is used to destroy skin pigment cells, so as your skin heals the spots may start to lighten. But cryotherapy should only be performed by an experienced dermatologist.
You should start using glycolic acid because it is thought to suppress the production of melanin, which may be why it is beneficial for reducing dark spots. Glycolic acid offers consumers an excellent and affordable option to fade dark spots in as little as four weeks.
Kojic acid blocks tyrosinase in turn inhibiting the production of excess pigment so it can help lighten existing sun spots and photodamage, fade the dark marks too. Kojic acid can begin to work in days, but it usually takes weeks to see an appreciable reduction in pigment. You will probably see difference in three or four weeks.
Dark spots on your legs are usually not a cause for concern, but you may want to mention them at your doctor visit especially if there are spots that are raised and not smooth, dark spots on your fingers, soles of your feet etc. So you should talk to your doctor spots on your skin, talk to your doctor or dermatologist about the safest and most effective types of treatment.
