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


Why Is pH Level Mentioned On The Package?

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


Is This Product Certified Eczema-Safe?

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

Answer


Can I Use The Product If I Am Pregnant?

We formulate without ingredients on the EU's prohibited substances list (Regulation No.1223/2009, Annex II). This formula is Dermatologist-Tested and Hypoallergenic. If you have any specific concerns, we recommend consulting your doctor prior to use.

Answer


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.

    Excellent body serum

    I have many skin sensitivities due to a medical condition and this serum makes my skin feel amazing! I love that it is made of clean, high quality ingredients and that there is a fragrance free option (which is what I use). This serum is easily absorbed right into the skin unlike some other brands in which the product would sit on top of the skin. I'm seeing results in that my skin is looking younger!

    The Best

    I am going to say the same thing about all of Necessaires products (the very best). I now use them exclusively and believe me, I have tried tons of brands. I tend to have dry skin, especially during the winter and using this product has eliminated that concern. I do mix them. I combine this with the Retinol and use it on my arms and legs. Absolutely no flaky skin!...and to be completely honest, I only use it once a week. Again, the very best.

    It has a consistency between a gel and a lotion and is easy to apply. It has as a soothing sensation which is very pleasant! More importantly fragrance free and so far in the one year I've been using it no irritation!

    This is, by far, my most often replenished body product of all time. I begin to get anxious if the bottle is getting light and I dont have a backup. It makes my skin so soft and smooth and makes any moisturizer I use after it so much more effective! Highly recommended.
