What is your advice when someone has oily skin?
Many sunscreens, especially those that are extra water resistant, tend to be very oily; this is what gives the shine and increases the risk of spots. I advise people to use a sunscreen that is labelled “non-comedogenic” or “oil free,” this means that it tends not to cause spots. Again, this was an important element in the development of Altruist – that it should be able to be used by those on treatments for acne, in particular isotretinoin.
