Dry skin underneath eyes?

So i've been using this new acne cream on my face, and it dried it all up.
i've always had bags underneath my eyes, but they don't really bother me. but when i felt the bags, it felt so nice when they were dry - they were so smooth :D
but then i looked in the mirror, and smiled, and i had gigantic wrinkles underneath them! so i've been moisturizing the hell out of them for the past 2 days, but they're still not gone.

they're not permanent (the wrinkles, that is), are they?

and do you have any recommendations for the moisturizer? right now i'm using nivea 'aqua sensation'

Yes, these products that work on one part (acne) also affect the naturally delicate eye area. The eye area doesn't have oil production like the rest of your face so it needs even more care.
Right now, be sure your diet is good with plenty of water to help the skin stay supple, lots of protein, grains, fruit & vegies to give the skin the best internal help possible.
For the outside, especially the eye area, a very heavy cream can actually be too much as it will weigh down that area. Unfortunately, once wrinkles come they're yours...you could go expensive and look into professional services--a deep moisturizing facial; services from skin specialists that are costly...
For home efforts, a regular cleansing, moisturizing routine & care for going into places like the sun, the pool, the cold will be very helpful. A lighter eye cream applied after morning and night cleansing is excellent & is what I do. Also, there are 'special creams' that can sort of make the wrinkles look lesser but won't take them away.
Personally, I love the Christian Dior cremes for face and eyes but there is Almay or Avene at your local drugstore..and these two are hypoallergenic which means no perfume so less drying to the skin.
I hope this helps:)
Oftentimes, drugstores will have "free" makeovers in their cosmetics departments...you might ask. If you try a department store be selective of which product line you would prefer to invest in.
Practice skin care as you would practice the piano and your skin will improve :)

Go to the health food store and buy yourself a 6$ bottle of jojoba oil. It is the best stuff ever for your skin. That all I use on my whole body. Its even gotten rid of my skin problems. Its safe to use all over your body and even in sensative parts.
Highly recommend it and it does NOT leave an oily residue that sits on your skin forever. It soaks right in.

first off, change the acne cream, or at least don't use it under your eyes.
A great moisturizer is coconut oil. It'll soothe the area and really help it too, plus it won't clog your pores.

I use moisturisers by dermalogica, they do some really good hydrating moistuisers, normally a local salon will sell dermalogica.
