Our Science

Efficacy is our goal

Lontreau is dedicated to creating products that are backed by science and tailored to your needs. We use clinically tested ingredients in efficacious doses, so you get the most out of every drop. We don’t believe in junk miles when we train, and that’s true of our skincare too.

Some of our featured ingredients include:

  • Vegetal Glycogen
  • Squalane
  • Vegan Collagen
  • Kakadu Plum Extract
  • Dragon Fruit Extract

Formulation Playbook

Lontreau formulations include a synergistic blend of clinically proven ingredients specifically designed for the needs of athletes and everyday movers.

We challenged ourselves to use the highest standards when it comes to clean. The average woman uses 12 personal products daily and is exposed to hundreds of chemicals - none of which are required to be tested for safety. We make products that are beyond clean. We avoid over 2,700 specific ingredients and types of ingredients that are used in mainstream beauty products.

We know you’re busy, that’s why our formulations are designed so you can just pump, emulsify, apply and go. The products in our Core 4 Kit can be pumped directly into the palm of your hand, emulsified together, and applied all at once to simplify your endurance skincare routine.

We err on the side of quality over quantity - just like with our training programs. Our formulations include synergistic blends of ingredient dense, clinically proven ingredients specifically designed for the needs of athletes.

All Lontreau products are designed to have primary and secondary benefits as opposed to single-ingredient products that just do one thing, requiring you to follow multi-step programs. In doing so, that’s part of our commitment to reduce the number of products you need for an endurance skincare routine.

Game Changer, Endurance Hydration, Recovery Hero and MVP all include our innovative Biomimetic Barrier Formulations. We use natural ingredients to mimic the skin's biochemical structure.
