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.

    Combined with the exfoliation lines, my skin is lovely and soft now!

    I read about the Body Exfoliator a few months ago on Buzzfeed and decided to give it a try to help manage my KP. After getting really good results, I decided to expand into some other products, this Body Serum included.

    I quickly realized that my menopausal-drying skin was improved with just the exfoliator alone after the end of two weeks. Patches that could have been described as scaly became soft and smooth. Once I added in the body wash and Body Serum, my skin became legitimately silky and supple. And even though I'm living through sub-zero temps with deeply dry air, my skin looks and feels amazing. This is the first winter in 20 years I am not waking up in the middle of the night to discover I'd been clawing at my skin in my sleep!

    Also, the reality is you do not have to slather on these products - my first tube of exfoliator lasted 2 months! A little goes a long way, especially with the exfoliator since it's both chemical and physical. As others have noted it is a little sticky, but I've learned if you use it sparingly and take the time to rub it in, it is a little less so. A layer of moisturizer on top and you're all set. I actually just ordered the Vitamin C Body Serum - I've been using a VitC serum on my face for a while now and decided to see if it compares!

    So yeah, you may think, "is it worth it?" Maybe in my 20's and 30's, I would have reverted to something slightly less expensive. But my middle-aged skin is loving the Necessaire line and is happily…

    Favorite body hydrating serum

    This alone may not be enough with someone who had super dry skin, but for myself during the spring and summer months in SoCal it is perfect. In the fall and winter I use this a a base and also the peptide moisturizer and it leaves my skin silky soft.
