Is this sunscreen good?
This sunscreen cost me £7. I don't know if it is working for me, but as of now, I don't notice any alarming hyperpigmentation, just persistent dark spots that won't go.
The reason I am asking is because it is SO much cheaper than all other sunscreens, with a lot more volume too, yet my skin hasn't had any bad reactions while using them ever. Please advise me.
I am 18 with dry skin type
