I have been using Altruist SPF50 (Amazon) religiously for the last couple of years, and have had a lot of hyperpigmentation / melasma appear on my forehead and cheekbones. Could there be an issue with Altruist not working properly?
I have not had any other hormonal changes to cause this and am positive I am using enough of the suncream. I run outside regularly and wear a cap as well to protect my face.
I have decided to change my sun protection just in case, but interested in any opinions!
