Skin Immune System
• Activated by keratinocytes or direct contact with Langerhans cells (in the case of microorganisms)
• Pro-inflammatory mediators release – recruit other cells of the skin immune system such as neutrophils, macrophages and lymphocytes – releasing other pro-inflammatory mediators
Langerhans
cells Neutrophils Lymphocytes Macrophages

Pro-inflammatory mediators
IL-1
Stimulate:
IL-4, IL-5, IL-10, INF- (interferon gama) and
TNF- (tumor necrosis factor gama)
Keratinocytes and
macrophages
IL-1 TNF- Stimulate:
IL-1, IL-6, IL-8 and eicosanoides (COX-2 e PGE2)
Cause fever and ECM destruction (MMPs) and
increase vascular permeability (edema)
Atopic dermatitis
and psoriasis
ECM – Extracellular Matrix
MMPs- Metalloproteinases
![Page 5: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/5.jpg)
Pro-inflammatory mediators
IL-6
Stimulate:
Antibody production, acute phase proteins and
angiogenesis
Many cells
INF- TNF- Stimulate:
IL-2 and IL-4 and activate macrophages
(phagocytosis)
Free radicals, impair structures
psoriasis
eczema and
psoriasis
INF- - Interferon gama
TNF- - Tumor necrosis factor gama

Pro-inflammatory mediators
NF-
Activates:
Cytokins and growth factors, but it posess
cyto-protective functions
Histamine
Increase:
• Allergic and atopic dermatites and sensitive skin
• Vasodilatation, edema, pruritus, pain
Atopic dermatitis,
eczema and psoriasis
IL-10 Controls:
Exaggerated immunological reactions (inhibits
macrophages and Langerhans cells reactivity)
![Page 7: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/7.jpg)
Pro-inflammatory mediators
Edema, hyperpigmentation
Vasodilatation, edema,
erythema, pain and pruritus
![Page 8: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/8.jpg)
Growth Factors
TGF-
Stimulate:
Immune system cells migration to the region, but it
reduces the cytokine production, phagocytosis and
Langerhans cells activation
Keratinocytes, Fibroblasts
and Lymphocytes
TGF- GM-CSF Maintenance of capillary integrity and regulates
tissue repair through proliferation of fibroblasts
and synthesis of ECM components
pro- and anti-
inflammatory
action
GM-CSF - granulocyte and macrophage stimulatory factor
TGF- - tissue growth factor alfa
ECM – extracellular matrix

Aging • Heat and visible light causes similar damages to those found in photoaging:
• MMPs
• free radicals
• inflammatory mediators
MMPs- Metalloproteinases

Physavie®
• Supercritical extract of Physalis angulata • Plant found in high solar incidence region
• Soothing properties similar to corticoids without side effects (inhibition of growth factors and acceleration of aging)
• Indicated for sensitive or sensitized skin
• Presents antiaging properties
![Page 12: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/12.jpg)
Physavie® • In vitro tests
• Inflammatory mediators • Growth factors • Antioxidant property • Extracellular matrix
• Ex vivo tests • Extracellular matrix
• Clinical trials • Preventive study - temperature, microcirculation and TEWL • Curative study – TEWL, erythema and subjective analysis • SPF – non interference in the SPF • Permeation

Physavie®
Benefits
• 100% biodegradable
• Has soothing properties equivalent to hydrocortisone without the adverse effects
• Has anti-pruritic and soothing properties, essential for sensitive and/or sensitized skin
• Regulates skin temperature and microcirculation, maintaining its baseline levels, even after external aggression
![Page 42: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/42.jpg)
Physavie®
Benefits
• Biologically reduces damage from infrared radiation and visible light;
• Has proven Anti-Aging Thermal Action;
• Can be associated with photoprotectors, with the appeal of reducing the damages caused by rays in the infrared wavelength and visible light, without interfering in the formation of erythema, needed in Solar Protection Factor (SPF) determination
![Page 43: Presentación de PowerPoint · eczema and psoriasis IL-10 Controls: Exaggerated immunological reactions (inhibits macrophages and Langerhans cells reactivity) Pro-inflammatory mediators](https://reader030.fdocuments.us/reader030/viewer/2022040515/5e719bde1080ca519c3faf77/html5/thumbnails/43.jpg)
Physavie® Application • Oil phase at a maximum of 80°C (for up to 15 minutes)
• pH 4,5-7,5
• Emulsions, gels, serums, tonics, soaps, oils for sensitive or sensitized skin
• Compatible with formulations containing both chemical and physical sunscreens
• For transparent formulas, please order specific version
Concentration of use 0.5-1.0% (w/w)
