Do cellulite creams/stretch mark creams work? Do you recommend a certain brand?

Unfortunately, no. They ‘work’ based on the claim that keeping skin hydrated will keep it from tearing. Well, in a super technical sense that is one way to hydrate, but it is not really going to prevent stretch marks (and it definitely does not affect cellulite). It is good, however, for alleviating that itchy skin feeling when skin starts to stretch. The key factor in stretch marks is genetics (thanks Mom!) and the only other tried-and-true prevention is gaining that weight slowly so that your skin has time to adjust. For hydration, I can’t say it enough, water & ice! Your body hydrates more efficiently than you can smear it from the outside with anything because your GI tract is actually meant to absorb fluid.

The only recommendatation that I have is that you choose hypoallergenic creams when you are using any kind of lotion. Your skin might be more sensitive during pregnancy and you'll be surpised what different reactions you might have to things that never bothered you before!
