The same way face serums address different issues like aging and acne, body serums target specific skin concerns.

The entire line of Vaseline® Intensive Care™ Healing Serums, for instance, offers three different variants. Vaseline® Intensive Care™ Healing Serum Advanced Relief focuses on moisturizing to heal severely dry skin. There's the Vaseline® Intensive Care™ Healing Serum Deep Repair, which moisturizes to soothe cracked skin and heal rough, dry skin. And Vaseline® Intensive Care™ Healing Serum Radiance Restore, which moisturizes to heal and restore dry, dull skin.

One of the best things about a body serum is the incredibly light consistency. Serums are immediately absorbed into the skin so you don't have to wait for them to dry before getting dressed. Vaseline gave our readers free product to try, and here is what they thought:

"It's very light, easy to blend and absorbs quickly into a powdered finish. I hate feeling sticky so that's a big plus from me," says TotalBeauty.com reviewer Thr33things about Vaseline® Intensive Care™ Healing Serum Advanced Relief, SRP $6.79.

"This serum proves that you don't need to use a [thick] lotion [in order to heal] dry skin," says TotalBeauty.com reviewer Val007.

Despite having a light consistency, body serums are able to keep skin feeling hydrated all day -- sometimes even longer.

"My skin felt lightly moisturized, and it really felt like the product soaked in," says TotalBeauty.com reviewer strawberrytime about Vaseline® Intensive Care™ Healing Serum Advanced Relief, SRP $6.79. "The next day, my skin still felt soft."

Basic moisturization will make your skin look temporarily better, but may not fix the underlying problem -- whether it's irritation, cracking, dullness or something else.

"I can tell it's actually healing my dry, winter skin … its long-lasting benefits are already showing," says TotalBeauty.com reviewer joeygurl81 about Vaseline® Intensive Care™ Healing Serum Advanced Relief, SRP $6.79.

"Today is the seventh day of testing this product, and I have seen an improvement in the texture and moisture of my skin," says TotalBeauty.com reviewer Jessicaviolett.

Skin care serums aren't known for their great scents, but body care versions not only smell fantastic, they also complement your existing fragrance library.

"I absolutely love how it smells," says Jessicaviolett. "The smell is not intense at all, but lingers perfectly and complements real fragrances, [like rose, amber and vanilla]," she says about Vaseline® Intensive Care™ Healing Serum Advanced Relief, SRP $6.79.
