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.

    Super soft skin without stickiness

    This body serum is one of my top 10 ride or die products. It's pricey, but It works better than any moisturizer I've ever used and leaves my skin feeling like silk. I apply it immediately after showering, leaving as much water on my body as I can prior to serum application . This both helps lock in additional moisture, and makes the product go a bit farther, as I can cover an entire leg with just two small pumps of the serum. There may be some initial tackiness, but after it dries completely it leaves no residue and my skin is incredibly soft. I do use an exfoliating loofah in the shower, but I have used the loofah without the body serum and my skin is not nearly as soft. There is no need (for me, at least) to follow up with a traditional moisturizer, which I typically hate because I don't like the sticky feeling of traditional moisturizers. This serum just leaves softness and nothing more. Full disclosure - I did purchase this at a discount from an online reseller site, but it works so well that when I finish my current bottle I will absolutely be ordering from The Necessaire and paying full price. It's worth every penny.

    Lightweight, smooth, and effective

    This serum seems to be the magic ticket for smoothing and soothing. I've had issues with acne and bumps on my arms, and very dry feet for years, and this, combined with the body cream, seems to be the fix. My skin looks pretty incredible after just a month of use.

    A pregnancy must have!

    They say stretch marks are genetic. My mom and sister both got them during pregnancy. I ordered this product the day I found out after extensive research on what could possibly be a real preventative as a girl who is serious about my skincare. The only answer was a clinical grade hyaluronic acid. I’ve been applying this twice a day my entire pregnancy I’m now 9 months and I just ordered my 4th bottle. I have zero stretch marks! I wish I could shout this from the roof tops because of the many misconceptions on lotions and oils for stretch marks preventatives. It starts with a solid hyaluronic acid and this product has not failed me. My skin quality overall as someone who struggles with dry skin and eczema has improved so much. I already subscribed and saved on Amazon because this will absolutely be a staple in my skincare/body care for the foreseeable future.
