I want to do Fractional CO2 Laser to get rid of sebaceous hyperplasia and to diminish pores. My skin is medium tan with warm undertones. 1. Will I experience hyperpigmentation post laser with my skin type? 2. I have very sensitive skin. How long would the downtime be? 3. Do I have to wear sunscreen post laser? Is Elta MD SPF 46 okay to use? 4. Can I use Cetaphil gentle cleanser to wash my face? 5. Can I use Avene Hydrance Optimale Light Hydrating Cream as a moisturizer?
