Are there any gentle exfoliating scrubs available?

Now that it's the dry season, I think I need to exfoliate my dead skin cells. Even though I apply moisturizer well, my skin feels rough and flaky.

I have tried using scrubs, but they hurt, and afterwards my skin gets very red and sore. So I don't really end up using them.

Could it be because the scrub isn't very good? Are there any scrubs gentle enough to use even on sensitive skin?

Please give me a recommendation~
