FAQs

Q:

What is the difference between hydration and moisturization?

A:

We refer to hydration as the water content within the cells that helps skin look and feel replenished and plump. We refer to moisturization as the ability to seal in moisture and to help strengthen the skin's natural protective barrier. The Body Serum is designed as a hydrator.

Answer

Q:

Why Is pH Level Mentioned On The Package?

A:

During the formulation process, we optimize the pH of the formula. We believe it directly impacts the safety and efficacy of the formula. The pH objective will vary based on product purpose. On the secondary packaging (carton) we provide a pH range. The reason pH range is indicated is that pH may vary during the manufacturing process and/or slightly change over time. Formulas that do not contain enough water will not have a pH listed.

Answer

Q:

Is This Product Certified Eczema-Safe?

A:

Yes. This product holds the Seal of Approval by the National Eczema Association.

A:

Answer

Q:

Is This Product Certified Gluten-Free, Soy-Free And Nut-Free?

This product is not certified gluten-free, soy-free or nut-free. This product is manufactured in a facility where gluten, soy and nuts may be used. If you have an allergy to gluten, soy or nuts, we recommend that you do not use this product. If you still wish to try, please consider a patch test.

Reviews Summary

Last updated 8/3/26

Customers say this body serum absorbs quickly and leaves skin feeling soft and smooth. Many reviews mention using it right after showering, either alone or as a base layer under moisturizer. While some note an initial tackiness, most find it dries without residue. The lightweight formula particularly appeals to those who dislike heavy lotions. Common feedback includes improved skin texture and hydration, especially during dry winter months. A few customers mention concerns about the packaging design and texture, though most praise its effectiveness for dry skin care.

Fabulous Proctor

For someone in her 60s, I'm so glad I added this to my skin routine. I've been using for about a month. The silky feel of the serum goes on nicely. Doesn't leave a greasy finish. My skin feels and looks smoother and hydrated. Highly recommend adding to a full body skincare routine.

Game changer !

I am over 60n and have very dry skin. This serum has definitely helped tremendously, along with using the lotion daily. It is not greasy and absorbs nicely. Highly recommend !
