I have been suffering from Melasma since the last 4-5 years, there are dark patches around my cheekbones and considering i have a fair skin tone, it is very much prominent and visible. I took cosmo peel and laser treatments 2 yrs ago which wasn't fruitful at all. I consulted a dermatologist and have been advised to use "Triluma" cream twice a week. Since i have started using it (since the past two weeks) i can see my skin flaking and being dry.. and whenever i use my sunscreen (Neutrogena Ultra Sheer) i feel a tingling burning sensation. Is this normal?
