Dr. Harlan recommends that anyone using SmartLotion® on their child do so with their Pediatrician or Dermatologist's supervision.

The FDA has not officially cleared hydrocortisone for use in children under 2.


At two months of age, the baby develops a deep red rash involving the face, crease of the neck and/ or body creases (flexures). This is known as infantile seborrheic dermatitis and can be associated with slight scaling, crusting or even moist exudates.


For this group of symptoms, Dr. Harlan typically treats his patients with the following routine, under their pediatrician's supervision:

First, Dr. Harlan has his patients apply diluted, vinegar-soaked cotton compresses to the affected areas for 3-5 minutes.

Next, he tells them to remove the compresses and apply SmartLotion® to the affected areas as a thin, disappearing layer. If needed, he recommends using a hair dryer to dry the area.

He has his patients repeat this routine 2x per day for up to 2 weeks.

The application of SmartLotion® must be dry with no excess moisture.

For extra sensitive, stingy, dry, rough faces, he recommends to first apply a recommended moisturizers before applying SmartLotion®.

For the infantile vinegar solution, he recommends the following: Mix 1/2 tablespoon of white vinegar into an 8 ounce glass of water.
