Youth Boost ExoSignal GF² Facial Serum is powered by our latest innovation, ExoSignal GF²™ Technology. This advanced formula combines plant-derived exosomes and stabilised dual growth factors to support the skin’s natural communication processes to help skin visibly renew, rebuild and rebalance.

The formula contains 30 billion plant-derived exosomes per bottle^, extracted from a specialised Centella asiatica extract. These microscopic messengers work with the skin's natural surface communication to help maintain balanced, resilient-looking skin.

Complementing these signals are dual plant based growth factors to visibly renew and support firmness and elasticity. To help maintain their stability and performance in a topical serum, these delicate molecules are protected using oleosome fusion technology.

The formula is further enhanced with Lamellar Technology to work in harmony with the skin barrier to support compatibility and effective delivery of key actives.

Designed as a multi-action, multi-pathway formula, the serum helps support the 9 visible dimensions of skin longevity, including firmness, elasticity, hydration, radiance, barrier strength, skin density, resilience, fine lines and pigmentation.

With continued use, skin appears smoother, firmer, brighterand more resilient, helping maintain healthier-looking skin for longer.

Apply afteractive treatment serums and before moisturiser.
Use morning and evening as part of your daily skincare routine.

Like a personal trainer for all your other skincare, we recommend using the ExoSignal GF Facial Serum daily with your existing A, B² or C active serum to support long-term vitality and resilience:

  • A Renewal : Visibly supports renewal and structure.
  • B² Hydrating : Supports hydration and barrier function.
  • C+ Firming : Supports firmness, elasticity and radiance.

Together with ExoSignal GF², they form a daily routine designed to support long-term skin vitality and resilience.

At the heart of the formula is ExoSignal GF²™ Technology,a multi-dimensional, multi-pathway
support system combining plant-derived growth factors and exosomes to support
the skin’s natural surface communication network to optimise skin fitness:

  • 30 billion plant-derived Exosomes per bottle^ (from a specialised Centella Asiatica extract) to support skin’s natural communication processes to promote balanced, resilient-looking skin.
  • Renew Growth Factors to support visible surface renewal for smoother, brighter-looking skin
  • Rebuild Growth Factors to help skin feel firmer and bouncier by supporting natural structure
  • Oleosome-fusion technology to enhance stability of growth factors, allowing effective topical delivery outside of a clinical setting

Together, they form a skin fitness system designed to support the visible longevity of the skin's appearance.
