Answer

Why is pH level important?

During the formulation process we optimize the pH as we believe it directly impacts skin's ability to recognize key ingredients and reap their benefits. The pH product will vary pending the design purpose of the product. On the packaging we provide a pH range as the pH may vary during the manufacturing process and/or slightly change over time.

Answer

What is the difference between hydration and moisturization?

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

Is this product gluten-free, soy-free and nut-free?

The Body Serum is gluten-free as confirmed by our ingredient suppliers. The Body Serum is not certified gluten-free, soy-free or nut-free. The Body Serum 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.

Answer

Can I use The Body Serum during pregnancy?

We formulate with clean, effective ingredients and without ingredients on the EU's prohibited substances list (Regulation No.1223/2009, Annex II). The Body Serum is Dermatologist-Tested and Hypoallergenic. If you have any specific concerns, we recommend consulting your doctor.

    Love, love, love...

    I absolutely love this stuff. I've been on the subscription plan for about a year and my skin has been transformed. The serum followed by the lotion is a dynamite combination!
