What is the difference between The Deodorant Gel and The Deodorant?

The Deodorant Gel and The Deodorant are formulated with our signature 5% AHA (Alpha Hydroxy Acid) complex to combat odor, treat discoloration and minimize bumps. The Deodorant Gel is a quick-dry clear liquid ideal for light-to-normal odor control. The Deodorant (cream) is an absorbent clay-based shield ideal for normal-to-heavy odor control.

Answer

Why is The Deodorant Gel formulated with Mandelic Acid?

The Deodorant Gel and The Deodorant are both formulated with Mandelic Acid to provide a low pH environment that inhibits the growth of odor-causing bacteria. While Mandelic Acid's primary role is to help provide clean odor control, the gentle exfoliation also helps to minimize shaving bumps.

Answer

Why is The Deodorant formulated without Ozokerite?

Nécessaire adheres to EU ingredient standards and EU ingredient listing. All ingredients inclusive of all incidentals are captured on our ingredient labels. During our development process of The Deodorant our clinical team and vendor partners were not able to find a clean Ozokerite as base for our formula. The available sources of Ozokerite that we found had incidental traces of BHT or Paraffin. We therefore used Sunflower Wax as our base. A Sunflower Was base is softer which means that there can be slight dome imperfections, but we welcome those imperfections in exchange for better ingredients.

Answer

Does The Deodorant contain Aluminum?

The Deodorant is Aluminum-Free, Baking Soda-Free, Ozokerite-Free, Paraben-Free, PEG-Free and Silicone-Free. The Deodorant adheres to EU formulation standard and EU ingredient listing. All ingredients inclusive of all incidentals are captured on the ingredient labeling across website and on pack. The Deodorant is dermatologist-tested, hypoallergenic and non-comedogenic.

Answer

Can I use The Deodorant Gel after I shave?

The Deodorant Gel is formulated with Mandelic Acid. Do not apply directly after shave. If you wish to try, we suggest a patch test.

    My new favorite deodorant! I love this updated formula as I found their gel deodorant less effective overall. The mandelic acid really works to significantly reduce razor bumps/irritation. This doesn’t leave a ton of residue behind, it melts well into the skin. Also love the scent!
