Because of the highest level of UVA protection available, it helps to prevent UNEVEN TONE, DARK SPOTS & appearance of WRINKLES. It helps to minimise the negative impact of environmental aggressors such as pollution. It's infused with actives to give moisture back to the skin and protect it from dehydration.
