Melasma is a chronic condition that can be difficult to treat. Treatment usually consists of bleaching creams, such as the Tri-Luma that you mentioned and other treatments (lasers, peels) and lifestyle changes (sun-protective behaviors). It is important to remember that bleaching creams should be monitored by your provider as you should not be on them long-term and must transition off and back on again throughout your management of this condition. Aside from creams, there are some lasers and peels that can help to minimize the appearance of melasma, but the single greatest thing you can do to help prevent it from getting worse is practicing sun-protective behaviors. This means wearing high-quality sunscreen (and reapplying), wearing hats, and seeking shade. Inflammation, heat, and hormones also play a role in melasma, so remember activities that cause heat and inflammation (such as waxing, sitting in saunas) may make the pigment appear worse. Because of its chronic nature, it is easy to be discouraged, but by seeing a provider experienced in treating melasma, you can have a management plan that it easy to follow.
