Coenzyme Q10 (CoQ10) is a well‐known antioxidant and has been used in many skincare products for anti‐ageing purpose. However, the molecular mechanisms of CoQ10 function in skin cells are not fully understood. In this paper, we compared the effects of CoQ10 on primary human dermal fibroblasts from three individuals, including adult. We demonstrated that CoQ10 treatment promoted proliferation of fibroblasts, increased type IV collagen expression and reduced UVR‐induced matrix metalloproteinases… 
Stimulatory effects of collagen production induced by coenzyme Q10 in cultured skin fibroblasts
CoQ 10 has the efficacy that it increases collagen production in skin, thereby there is possible of the anti-aging by CoQ 10 in Japan which reached an aging society, so that it might be based on new physiological function by Co Q 10.
Improving the anti-ageing activity of coenzyme Q10 through protransfersome-loaded emulgel
The in vivo study revealed that Protransf-CoQ10 Emulgel successfully increases the collagen density and number of fibroblast cells in UV radiation skin-aged induced-mice which reflects its potential for repairing the skin ageing process.
Avaliação da eficácia in vivo da L-arginina na elasticidade da pele
The results suggested that the application of L-arginine improves the skin resistance to traction force in female elder mice and L- arginine promotes the formation of a higher amount of collagen and elastic fibers in the skin when applied at a concentration of 15%.

The Use of Coenzyme Q10 in Cardiovascular Diseases
Clinical evidence shows that CoQ10 supplementation for prolonged periods is safe, well-tolerated and significantly increases the concentration of CoQ8 in plasma up to 3–5 µg/mL, and increases the NO levels for vasodilation.
Antioxidant and Anti-Inflammatory Effects of Selected Natural Compounds Contained in a Dietary Supplement on Two Human Immortalized Keratinocyte Lines
The findings suggest that the combined formulation may have the potential to powerfully inhibit oxidative stress and inflammation at skin level.
Coenzyme Q10 Supplementation as an Adjuvant Therapy Potentially Increase Serum Superoxide Dismutase Levels in Acne Vulgaris Patients
CoQ10 supplementation can increase serum SOD levels and improve the severity of AV, a chronic inflammatory disease in the pilosebaceous unit, and the use of antioxidants like coenzyme Q10 as adjuvant therapy is expected to be beneficial for AV.


Coenzyme Q10 protects against oxidative stress‐induced cell death and enhances the synthesis of basement membrane components in dermal and epidermal cells
Protecting epidermis against oxidative stress and enhancement of production of epidermal basement membrane components may be involved in the antiaging properties of CoQ10 in skin.
A novel anti‐ageing mechanism for retinol: induction of dermal elastin synthesis and elastin fibre formation
It is shown that retinol (ROL), known to enhance dermal collagen production, is also enhancing elastin fibre formation in cultured human dermal fibroblasts, demonstrating that ROL exerts its anti‐ageing benefits not only via enhanced epidermal proliferation and increased collagenproduction, but also through an increase inElastin production and assembly.
LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression
LOXL can be considered as a new target to reinduce elastogenesis at the adult age, because its stimulation by a dill extract is correlated with increased elastin detection, suggesting an increase inElastogenesis efficiency.
The pathogenesis of photoaging: the role of neutrophils and neutrophil-derived enzymes.
Clinical data indicate that high(er) doses ofUV, IR, and heat are necessary to induce photoaging or photoaging-like pathology in the skin, and it is proposed that MMPs generated by suberythemogenic doses of UV and low doses of IR/heat are involved in cellular processes other than ECM degradation.
Molecular basis of sun-induced premature skin ageing and retinoid antagonism
It is proposed that elevated metalloprotein-ases, resulting from activation of AP-1 and NF-KB by low-dose solar irradiation, degrade collagen and elastin in skin, which would result in solar scars, which through accumulation from a lifetime of repeated low- dose sunlight exposure could cause premature skin ageing (photoageing).
Extracts from Glycine max (soybean) induce elastin synthesis and inhibit elastase activity
The studies show that non‐denatured Glycine max (soybean) extracts induced elastin promoter activity, inhibited elastase activity and protected elastic fibres from degradation by exogenous elastases in vitro, suggesting that non-denaturing soybean extracts may be used as skin care agents to reduce the signs of skin ageing.
UVB‐irradiated human keratinocytes and interleukin‐1&agr; indirectly increase MAP kinase/AP‐1 activation and MMP‐1 production in UVA‐irradiated dermal fibroblasts
IL‐1 may play an important role in the paracrine activation and dermal collagen excessive degradation leading to skin photoaging by indirectly promoting MMP‐1 production in UVA‐irradiated fibroblasts by increasing MAP kinase/AP‐1 activity.
Coenzyme Q10 inhibits mitochondrial complex‐1 down‐regulation and nuclear factor‐kappa B activation
It is suggested that enhancing coenzyme Q10 synthesis and suppressing the induction of NF‐kappa B, may provide neuroprotection.
