You have to apply Melacare cream only at bedtime before you go to sleep, and wash it off in the morning.
Melacare Cream is used to cure and slow the process of darkening skin, which is usually caused by too much tanning as well as other factors. This cream works very well if it is used and applied properly. You should only apply Melacare Cream at night just before you go to bed, wash it off in the morning and apply some sunscreen, if you intend on going outdoors. Failure to do this will cause significant damage to your skin as it will go black.
If your skin becomes irritated because of using Melacare Cream, you have to stop using it for at least for a month. In the meanwhile, resort to homemade natural products. Natural products will give your skin time to heal and regain its full health before you continue with Melacare Cream.
Melacare Cream contains hydroquinone, which is great for treating melasma on the face and it can stop skin irritation. The ingredient hydroquinone undergoes strong reactions when exposed to the sun, and this goes on to mean that you cannot be in the sunlight after applying it as it will bring about photoallergic reactions that will contribute to the darkening of your skin.
Note that during that time you stop the usage of Melacare Cream to give your skin time to heal, try to take natural supplements. Eat plenty of fruits and vegetables, drink lots of water and other fluids and use natural skin care products as they will help rebuild your skin.
