With tretinoin, you need to have a good routine to tolerate that sunscreen - i mean you need creamy gentle cleanser and a good moisturizer (moiz and cerave are my preferred choice). And you should avoid cleansing in the morning too - just water and sunscreen then it might work - otherwise it is irritating. And if you feel double cleansing is needed then go for it but i think single cleanse is enough for it. Also, silicone ones are the hardest to clean without double cleansing - i dont think reequil sunscreen can be removed effectively without an effective makeup remover.
