Retino a Cream Question?

Hi, Retin A has been discontinued in the UK, which means my doctor can't prescribe it (I'd been using Retin A 0.01% gel for 2 years). Instead they offered Acnemycin which has antibiotics. I'm wary about putting that on my face every night so in desperation I bought some Retin A online at Inhousepharmacy. It's called Retino A cream 0.05% and says it's made my Johnson&Johnson. It looks legit enough however when I put it on I feel no tingling that I expected having upped the dose. I'm worried it's a fake.
