Where Legacy Meets Innovation
L’ÉTERNEL was born from a 30-year journey led by a Harvard Medical School clinical scientist and a team of dermatologists. Witnessing the limitations of traditional skincare, they sought to create solutions that go beyond surface-level care. Their research uncovered a universal truth: true radiance stems from the skin’s ability to heal and renew itself.
Harnessing proprietary CryoTangent™ Technology, the team pioneered a dual-chamber system that isolates freeze-dried actives—full-spectrum conditioned media and exosomes—in powdered form, preserving their potency until activation. Paired with Nano Liposome Delivery, which binds ceramides to mimic the skin’s natural barrier, our formulas penetrate deeply for cellular-level repair.

30 Years of Clinical Studies
Developed by Harvard Medical School Dermatologists and Scientists
Rigorously tested in clinical trials, L’ÉTERNEL products demonstrate remarkable efficacy: accelerated wound healing, wrinkle reduction, and strengthened resilience. With zero allergic reactions in 50-subject trials and INCI-compliant, allergen-free formulations, we redefine safety and performance. This is skincare engineered not just to restore, but to revolutionize.

TRADEMARKED
TECHNOLOGIES
Advanced Lyophilization Technology
Concentrates and Stabilizes Rare Active Ingredients
Stem cells are highly unstable active ingredients that can only remain active for about 7 days once removed from temperatures of below -196ºC. To fully stabilize and preserve the efficacy of this precious ingredient, our team of industry leading experts have integrated the most advanced lyophilization technology into this product, producing a freeze-dried powder which is stable and can be preserved for up to 2 years. This innovative technology allows our CryoTangent™ Complex to retain its full spectrum of growth factors, cytokines, and anti-inflammatory factors, while extending its shelf life from 7-14 days to 2 years.



NFC Nano Liposome Encapsulation Technology
Active Release of Nano-formulation for Deep Penetration
With an overwhelming number of products in the market that use large molecule ingredients, that cannot penetrate the skin’s surface and be absorbed, our team of skincare experts have integrated an NFC nano liposome encapsulation technology into our serum. This breakthrough technology allows our elaborately crafted active ingredients to penetrate deeply into the skin's epidermal layer, allowing the ingredients to be activated at the skin’s deepest layers, and fully absorbed.
Active ingredients are encapsulated into nano size liposomes, approximately 1000 times smaller than the average molecule size of traditional skincare product ingredients. This enables our products to penetrate the skin’s deepest layers, achieving revitalized skin that is more plump and nourished from within.
Superior Product Quality
The vast spectrum of growth factors and anti-inflammatory factors in our CryoTangent™ Complex are exclusively cultured from USA AABB and FDA accredited umbilical cord tissue super seed MSCs. In comparison to stem cells extracted from other sources, such as, embryonic, placenta, bone marrow, fat, and adipose tissue, stem cells extracted from umbilical cord tissue are less viable to external pollutants, such as, viruses, drugs, and other contaminants; it is the most primitive and most highly differentiative primeval stem cell with the highest purity. However, the quantity of stem cells extractable from this source is extremely minor, and it requires highly sophisticated technology, as well as a highly experienced team of cellular experts. Thus, the capacity of this technology is only mastered by a few of the world’s most elite medical teams.
As indicated by various clinical trials and studies, mesenchymal stem cells have shown significant results in the rapid repair of damaged skin cells, and has transcended the capabilities of traditional singular surface effect products currently existing in the market. L’ÉTERNEL products targets skin aging at its origin, stimulating cell regeneration, reducing redness and irritation, empowering the skin with impeccable resilience.
