Omega 3 Oil & Skin Health
Omega 3 Oil increases biodiversity in gut microbiota (may have favourable effects on decreasing bacteria’s risk of obesity and inflammation). It effectively reduces inflammatory skin conditions, helps hydration, wound healing, protects against sun damage, and heart and brain protection. Anti-inflammatory reaction across the body = essential fatty acid as we cannot produce our own. Commonly in West, imbalance of omega 6:omega 3 ratio. The ratio should be around 3:1, more commonly 15:1 in Western countries. ZinZino has a test to determine the fat content of cells. Omega 3 and omega six oil balance plays a vital role in skin health.
Essential Fatty Acids and Skin Health
- The body cannot produce essential fatty acids (EFA) and, therefore, must be ingested. The two groups of EFA are Omega-6 (n-6) and omega-3 (n-3) polyunsaturated fatty acids (PUFAs).
- Both omega-6 and omega-3 are critical for skin function and appearance.
- Metabolism of the essential fatty acids – linoleic acid and α-linolenic acid, is limited in the skin, so some of their derivatives are considered conditionally essential and must be absorbed topically or ingested.
- Omega 6 is essential for forming ceramides, one of 3 lipids required to create an effective barrier to the skin’s stratum corneum.
- Omega 6 and omega three are required to produce sebum elements – made in the sebaceous gland and secreted onto the skin surface.
- Both omega-6 and omega-3 give rise to potent signalling molecules, called eicosanoids, necessary for inflammatory and immune signalling.
- EFA’S can be absorbed through the skin’s surface, so either topical or oral means effectively supply EFAs to the skin and body.
Omega-6 fatty oils are sunflower, safflower, evening primrose.
Omega 3 -rich oils are flaxseed, chia seeds, green sea vegetables, algae & fish oil.
Omega 3 & Omega 6 –for skin beauty and health
Omega 3 & 6 are required to produce the significant lipids needed for normal skin barrier function and, as it turns out, for the cosmetic appearance.
Omega-3 PUFAs have a protective role in reducing sun damage, signs of skin aging and dampening inflammatory skin conditions.
Omega-6 fatty acids help alleviates symptoms associated with skin sensitivity and inflammatory skin disorders.
Essential fatty acids in a correct ratio of 3:1 – 1:1 have beneficial effects in settling acne, eczema, atopic dermatitis, psoriasis, rosacea and other inflammatory skin disorders.
What are the lipids | oils in your skin?
The lipid or oils in your skin are found in the epidermal and dermal layers. The epidermis is the skin’s very surface, forming a protective barrier, whereas the dermis is sandwiched between the epidermis and the fat layer called subcutis.
Epidermal lipids consist of the lipid bilayers contained around corneocytes in the stratum corneum and the sebum secreted onto the skin surface by oil glands.
The lipids of the stratum corneum lipid layers. The EFAs required to form the lipid matrix in the skin’s surface layer is incorporated into the epidermis basal layer’s keratinocytes. As the keratocytes differentiate and move to the surface, the keratinocytes parcel the lipids into an organelle called a lamellar body. These lamella bodies are extruded and rearranged into the sheets that encase the corneocytes.
- Linoleic acid (omega-6) is the most abundant PUFA in the epidermis and is essential for making ceramides crucial to barrier function.
- Arachidonic acid (AA) (omega-6) PUFA is the second most abundant in the epidermis and is found in epidermal cells’ membranes. It is a significant source of epidermal eicosanoids released from the membrane, which helps with skin inflammatory response.
- Omega-3 comprise less than 2% of epidermal fatty acids, but they serve critical immune modulation roles and significantly alter eicosanoids in the skin. Having a correct body ratio of omega 6 – omega -3 is essential for the skin’s immune function and the entire body.
The primary role of EFAs in the dermis relates to the production of molecules that mediate an inflammatory response. Omega 3 help decrease UV damage by minimising collagen damage.
Fatty acid metabolites from the dermis also act on cells in the epidermis, so anti-inflammatory eicosanoids produced in the dermis can inhibit pro-inflammatory eicosanoids in the epidermis.
