THE ULTIMATE HANDCREAM = LA PRAIRIE
You will never regret this purchase! It works MAGIC! The price is deathly (135$CAD for me) but both my mom and I are like hardcore addicts to this handcream! I love La Prairie, and this is their absolute best product and it works even AFTER you wash your hands (well... as long as you don't wash and scrub them excessively with loads of detergents and sulfates). One application a day is all you need and it dries really fast (none of that yucky greasiness like L'occitane's... ughhhhh).
Eucerin is probably second best and very much afforable at about 10$ but the result is not the same imo. Once you wash your hands, the dryness comes back like any other cream, so you gotta reapply and reapply.
Hmmm... also I recently discovered another really good handcream: Lancome's Nutrix Royal (although I find the collection's bodycream is even more fantastic than the handcream). The handcream has similar qualities as La Prairie's imo and also dries very fast (and leaves somewhat of a matte feeling???). I just bought it and used it last night and it seems to be very good. I haven't reapplied yet, but my hands are still quite supple (no dryness yet, no flaking, but the skin around my nails and cuticles are starting). Anyway, it's a more affordable version at 40$, but I'll see how it does in the long run before making any permanent judgements on it.
