Hello. I am 31 years old and mu dermatologist told me to use Avene Retrinal 0.1% every night for treating dark spots that resulted from the prolonged use of contraceptives and also as an anti-aging treatment. I wanted to know if It is save to use during the day Solvaderm Stemuderm as a complementary anti-aging product or is it counterproductive to combine both medications. Thank you.
