Just a question about holidays. I know you have to be super careful about sun exposure and I wear a sunscreen daily which seems to be suffice in the UK.
I am thinking well ahead, but what do you do on a holiday say in Italy in the height of summer? I would always use 50spf on my face but I'm wondering if this is enough? Some conflicting advice when I have searched, from using a sunblock is enough to not using for 2 weeks prior but then your skin will go back to pre Retin A.
And as a side question any long term users noticed a difference in your skin tone, my skin is smoother but I still have quite blotchy skin.
