Matatizo yako jaribu sunscreen and sio sunblock....angalia ushauri huu, for everyday use, my dermatologist recommends using a sunscreen with a minimum of SPF 15 but says that it would be even better if it was SPF 30+. For days when you know you will be out in the sun for longer hours, it's best to bump it up to SPF 40+. Also, look for a sunscreen with a PPD of around 8 (preferably higher) for decent UVA protection. If your skin is quite fair, you may need a stronger sunscreen as well.
