What Is The Difference Between The Deodorant And The Deodorant Gel?

The Deodorant and The Deodorant Gel both contain Mandelic Acid as the active ingredient for odor protection. The Deodorant is a soft solid stick ideal for normal-to-heavy odor protection. The Deodorant Gel is a clear, quick-dry and no residue liquid gel ideal for light-to-normal odor protection.

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 a pH range is indicated is that pH may vary during the manufacturing process and/or slightly change over time. Formula that does not contain enough water, will not have a pH listed.

Answer

Is This Product Certified Eczema-Safe?

No. This product does not hold 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.

    The best deodorant in all departments:

    Fantastic scent ✅

    Long-lasting wear ✅

    Sweat control ✅

    This is my first time using a mandelic acid deodorant and I am so happy with the results. Necessaire is my favorite brand!

    Don’t Reformulate

    I used a lot of different deodorant, usually with magnesium and sink in it, but they are not as good as this one. I love that all of the products from Neccesaire have a low pH. I use the deodorant all over my body, not just my own arms. I love that it’s acidic, and has Mandelic Acid, Triethyl Citrate, and Zinc Ricinoleate. The formula is science forward, low pH, moisturizing, it’s thin in the best way. It feels like a velvety oil I think due to the starch. I would hate to see this reformulated, and I hate that I waited so long to try. Both the gel and solid work very well. The solid just works better and is harder to sweat off. Sometimes I use both.

    Finally!

    I have been searching several months for something new as I have been going through a sudden change with my underarms. Out of nowhere, I developed an order that took me by surprise and nothing was helping. Thank you Necessaire for creating a product that actually works for me. This was not an easy search as I have tried a bunch. You work and I will forever be grateful.

    this is my go to deo. i wish it was available in hinoki scent though so so so badly! Sometimes the eucalyptus feels a but masculine but it does work really well. I usually keep it one at home and one with me in my daybag and apply a few times through out the day.
