Best sunscreen to use with Retin-A
Any dermatologist will have their preference for sunscreens. I certainly do and have the entire time I've been in practice. But the best answer for this question is that "the best sunscreen is the one you are willing to use and wear every day." For many patients on Retin-A I find that they prefer a creamier sunscreen because they need more moisturization in their skin. A good one is DML Daily Facial Moisturizer SPF 25 by Person & Covey. It's non-comedogenic so it won't cause acne; it has great ingredients that protect against UVA and UVB damage; and it has moisturizer too. You can buy it directly from the company's website.
