Why doesn't the hydrocortisone cause side effects?

The hydrocortisone in SmartLotion® doesn't cause side effects for these two reasons:

  1. It is low strength, which makes it safer for extended use.                
  2. The prebiotic sulfur in SmartLotion® enhances the hydrocortisone to protect your skin from any possible side effects.

Dr. Harlan proved that SmartLotion® is safe for extended daily use in his 2008 study, Steroid Acne and Rebound Phenomenon, published in the Journal of Drugs and Dermatology.

I have a skin condition not listed on your site. Can SmartLotion® help me?

Most likely, yes, however:

  1. Check the extended skin care guide available here and make sure your skin condition is not already covered.                        
  2. If it is not, email us at support@harlanmd.com. Dr. Harlan can provide personalized, condition-specific instructions for using SmartLotion®.                
  3. Consult your dermatologist.

Does SmartLotion® interact with any medications?


I think I may be allergic to an ingredient, how do I safely test SmartLotion® on my skin?

First do a Test Site. On an inner forearm, apply a small chocolate chip size dollop of SmartLotion® daily for 3 days. If you react to the product, send it back for a full refund.

How long does SmartLotion® take to work?

Many customers experience itch and pain relief almost immediately, or within 1 to 2 days.

Depending on the severity of your condition, your flare-up could be clear in as little as a few days or up to 3 to 4 weeks.

If your flare-up is extremely severe, although your skin might not be clear in this time you should see a noticeable improvement.

Be sure to follow the instructions provided in the skin care guide for best results.

Especially with atopic dermatitis (eczema), it is EXTREMELY important to moisturize frequently.

Can I use SmartLotion® on my eyelids?

Yes. SmartLotion® is safe to apply anywhere on the body. You won't need to apply as much or as often as flare-ups on the thicker parts of your skin. See the skin care guide for details.

Is SmartLotion® safe for children, infants and toddlers?

Yes. Be sure to follow the infant/ child specific care guide available in the skin care guide.

I am allergic to sulfa drugs. Can I use SmartLotion®?

Yes. Sulfa drugs (common antibiotics) are completely unrelated to the natural prebiotic sulfur featured in the SmartLotion® formula.

After my skin is clear, how much SmartLotion® do I have to use?

It depends on your skin condition, how large your affected area is, and how severe your symptoms are.

Prevention usage is detailed in right here in the skin care guide.

For minor flare-up prevention, 1 bottle of SmartLotion® can last 3 to 4 months.

What do I do if SmartLotion® is not working for me?
