1. Biomimetic Design: Matching Your Skin’s Chemistry
Biomimicry involves developing lab-synthesized ingredients designed to mimic specific substances the body produces naturally. This approach represents a key strategy in addressing skin aging: providing the skin with bio-compatible molecules, which may allow for more efficient utilization and for support of the skin's natural repair processes [4].
- Recombinant Peptides: These are proteins created in a lab to match the specific "signaling" molecules in skin. When applied, they may support natural processes, such as producing collagen or repairing the skin barrier [4].
Example: sh-Oligopeptide-1 (EGF) - bio-identical version of the Epidermal Growth Factor that helps speed up natural skin renewal. sh-Polypeptide-121 - a bio-designed, vegan collagen fragment that is small enough to integrate with the skin [3].
- Metabolic Engineering: This is a process where scientists use microbes (like yeast) to produce high-purity ingredients. Producing ingredients in these controlled environments can help provide consistency and quality while offering an alternative route to sourcing plant or animal derived materials [4, 5].
Example: Squalane. While the skin naturally contains squalene as part of sebum, squalene as an ingredient is prone to oxidation. Squalane, a more stable derivative, can be produced through microbe fermentation and is commonly used in skincare as an emollient that helps support the skin barrier and reduce moisture loss [4].
2. Advanced Delivery:
One of the biggest challenges in skincare is maintaining ingredient stability and optimizing delivery. If an ingredient degrades before being used, its ability to perform as intended may be reduced. Technologies such as vectorization are designed to help improve stability and delivery [6].
- Vectorization: A way to encapsulate or 'pack' actives to help protect their stability and support their delivery within the skin [6].
We don’t see the word “vectorization” on ingredient lists. Instead, we see the materials used to carry the ingredient, such as:
Lecithin / Phospholipids → may be used in liposomal systems
Hydroxypropyl Cyclodextrin → may be used in encapsulation systems
Cetyl Palmitate / Glyceryl Behenate + polymers → may be used in lipid-based nano-carrier systems
- Liposomes: These are tiny spheres made of the same fatty materials (lipids) found in skin. Because the skin recognizes these lipids, it improves compatibility with skin which may allow them to more easily pass into the surface more easily [6].
Example: Hydrogenated Lecithin. On a label, this often indicates the presence of liposomal systems that can support the delivery of active to the skin, helping improve their distribution within the upper skin layers.
- Extracellular Vesicles (EVs): These are biological "bubbles" that cells use to send information to one another. In skincare, they are used as efficient carriers because they are compatible with human skin [7].
Example: Panax Ginseng Root Vesicles (or Panax Ginseng Exosomes) The isolated extracellular vesicles of the root carry a dense concentration of “signaling” proteins, lipids, which may have an anti-aging role.
