Anyone with dry, sensitive skin and can recommend SPF for day to day use and possibly also retinol? I'm just over 40 and generally my skin is quite good, except sensitive (I've had reaction for example to Aveeno cream in my face). I'm thinking of trying Paula's choice Resist Anti-Aging Retinol Serum as it's' available to try on travel size (due to sensitive skin) so interested in feedback on it, but open to other suggestions as well.
