SPF 30 and SPF 25: Both the bioderma moisturizer and la roche posay powder are effective sunscreen. May need to reapply products if out in sun for multiple hours. No need to use vitamin C serum on skin- vitamin C is not a sunscreen. Also avoid outdoors from 10 am to 2 pm as sun is most intense during these hours.
