The Beauty of TFC8®

Our proven results are powered by Professor Bader's TFC8®, or Trigger Factor Complex - an exclusive patented technology comprised of over 40 ingredients and inspired by over 30 years of research, innovation and clinical study.


TFC8® technology guides key nutrients and powerful natural ingredients to the skin, creating and supporting an optimal environment for cellular renewal.


TFC8® turns potent base formulations into smarter, adaptive skincare capable of addressing individualized concerns - such as the appearance of fine lines and wrinkles, redness, hyperpigmentation, cellulite, stretch marks, and damage caused by external stressors.


TFC8® nourishes and protects, training the skin for the long-term. Resulting skin looks and feels healthier, firmer, stronger, and more even over time.


The Applicator

An innovative 25-micro bristle applicator for gentle, ultra-precise application

  • Made of pure pharma-grade synthetic material, no use of glues, fibers, metal, or additives that could adhere to or irritate the skin
  • Pharma-grade micro bristle allows for more hygienic application
  • Designed to load and dispense the optimal amount of product for more even, effective application
  • Soft, flexible tool enables use in hard-to-access areas, including along the root of the lash line


Key Ingredients

Augustinus Bader skincare is formulated with sustainably-sourced, high potency botanicals and bio-engineered clean actives, where possible, to reduce environmental impact.


Powered by our patented TFC8® technology and formulated with rejuvenating Roselle and Safflower Extracts and hair superheroes Biotin and Red Winter Algae.

Roselle and Safflower Extracts

Abundant in phytosterols and polyphenols that increase circulation to encourage regrowth and decrease the inflammation and oxidative stress that can trigger hair loss.


A form of Vitamin B also known as “Vitamin H” for its importance to hair health. Helps metabolize amino acids, which boosts production of keratin, supporting increased natural hair growth and improved hair health and strength.

Red Winter Algae

A marine extract. Abundant in arginine and taurine, two essential molecules for preventing hair loss, stimulating cells responsible for hair growth, and improving the density of hair.

Hyaluronic Acid Complex

A next-gen hydrator with an optimal ratio of small and large Hyaluronic Acid molecules. Creates a moisture barrier around the hair shaft to optimize keratin structure and create smoother, healthier-looking lashes and brows.

Castor Oil

A non-comedogenic hair nourisher. Abundant in restorative fatty acids known to support the growth of thicker, longer lashes and brows.

Our latest advancement, The Eyebrow And Lash Enhancing Serum, utilizes the power of our proprietary TFC8® to address the underlying cause of diminishing lashes and thinning brows. The unparalleled solution integrates cutting-edge science into a clean irritant-free formula, ensuring the delicate eye area is protected while optimizing hair growth and resilience and revitalizing follicle function for fuller, stronger, healthier-looking brows and lashes.
