The crystals and gel are super-absorbent materials that offer significant benefits: drawing wetness away from baby's skin, as well as helping to keep baby's skin healthy. In Huggies diapers, super-absorbent material is mixed with the diaper padding, turning liquid into a gel to help prevent leakage. You may occasionally see small beads of gel on the diaper or on your baby, but the gel is nontoxic and not harmful. The safety of super-absorbent material has been proven in over 450 consumer safety tests studying every which way a person could come in contact with it.
