When should I use Aquaphor instead of Eucerin?
As a general rule, use Aquaphor when skin is healing. Aquaphor intensively moisturizes, soothes and protects dry, cracked or irritated skin while it helps heal. Aquaphor will also help prevent chafing and chapping. Eucerin moisturizers are also very effective, but are more suitable for use under clothing and makeup because they absorb into the skin more quickly than Aquaphor does.
