Mechanism of Action
Coenzyme Q10 (Ubiquinone)
CoQ10 (ubiquinone) exists in the mitochondrial inner membrane as part of the electron transport chain (Complexes I, II, and III), where it shuttles electrons for ATP production via oxidative phosphorylation—the fundamental cellular energy process. Skin CoQ10 levels decline approximately 1% per year after age 30. By maintaining mitochondrial function and ATP production in aging keratinocytes and fibroblasts, CoQ10 supports energy-dependent repair processes: DNA repair, protein synthesis, and cellular turnover. As a lipophilic antioxidant, it neutralizes free radicals in membranes (including peroxyl radicals) and regenerates vitamin E (tocopherol) from its radical form. CoQ10 directly inhibits UVA-induced expression of matrix metalloproteinase-1 (MMP-1, interstitial collagenase), preventing photoaging-related collagen breakdown. It may also reduce IL-6 and other inflammatory mediators. Ubiquinol (the reduced form) is more potent but less stable in formulations. Oil-based or liposomal delivery enhances penetration through the stratum corneum.
Matrixyl (Palmitoyl Pentapeptide-4)
Matrixyl (palmitoyl pentapeptide-4, Pal-KTTKS) is a matrikine—a bioactive collagen fragment mimicking Lys-Thr-Thr-Lys-Ser from the alpha-1 chain of collagen I. This sequence binds integrin receptors on dermal fibroblasts, triggering TGF-beta/Smad and MAPK/ERK signaling that upregulates ECM synthesis genes. Fibroblasts increase production of collagen I, III, IV, fibronectin, elastin, and glycosaminoglycans including hyaluronic acid—recreating the wound-healing signal without tissue damage. The C16 palmitoyl chain enhances lipophilicity and stratum corneum penetration via intercellular lipid partitioning. Unlike retinoids, Matrixyl does not accelerate epidermal turnover, explaining its lack of irritation. Clinical studies show wrinkle reduction comparable to retinol.

Full Profiles
Coenzyme Q10 (Ubiquinone) →
A naturally occurring antioxidant present in every cell that declines significantly with age. In the skin, CoQ10 protects against oxidative damage from UV radiation and pollution, supports cellular energy production in keratinocytes and fibroblasts, and reduces the depth of wrinkles. It is both an antioxidant and an energizer of the cellular processes that maintain skin health.
Matrixyl (Palmitoyl Pentapeptide-4) →
One of the most studied anti-aging peptides. Matrixyl is a signal peptide that mimics collagen fragments (matrikines), tricking fibroblasts into thinking collagen has been broken down and needs to be replaced. This stimulates new collagen, elastin, and hyaluronic acid production. Clinical studies show visible wrinkle reduction comparable to retinol but without any irritation.
