Why we need lipids!
Healthy skin starts with a healthy skin barrier. Our skin is based on a lipid/oil chemical structure and designed to be selectively absorbent, allowing penetration of oil soluble constituents which play an important role in our epidermal barrier function for moisture, suppleness and to prevent skin disorders.
Essential fatty acids (omega 3 and 6) can’t be synthesized by the body and we need to get it from our food or applied them topically.
Research shows that essential fatty acid (EFA) deficiency ,especially the omega 6 or linoleic acid (LA and GLA) leads to abnormalities in skin function, resulting in dry, flaky skin. The lack of EFAs can’t protect the skin barrier against excessive water loss. (4) The symptoms in these skin disorders are reversible by the addition of EFAs in the diet, or by topical application. Increasing the levels of key EFAs increases cell membrane fluidity, enhances barrier function and repair, decreases trans-epidermal water loss, improves moisturization, cell signaling, cell immunity, and anti-inflammatory activity. (5)
Linoleic acid (omega 6) is the most abundant polyunsaturated fatty acid in human skin and is indispensable.
As we age, the amount of lipids decrease significantly and especially which is why we are more prone to dry skin as we age.
The consumption of borage oil induced statistically significant improvement of the epidermal barrier function in the elderly people. (7)
Topical application of EFAs has the added benefit of actually adding moisture and hydration and these natural constituents become well absorbed into the epidermal , dermal layers and eventually to the rest of the body. A significant portion of ingested EFAs may be oxidized by the liver before reaching skin tissues, topical application may be a more efficient route of delivery for skin effects, especially during deficiency.

Normal skin type: "Normal" is a term used to refer to well-balanced skin. The T-zone (forehead, chin, and nose) may be a bit oily, but overall sebum and moisture are balanced, and the skin is neither too oily nor too dry. Corpa Flora recommends using the DUOS right after the cleansing step, by applying into the palm 1/2 a pump of facial oil and 1/2 a pump of hydration enhancer serum. Rub your hands together and apply to the face, neck and décolleté. If the skin is too dry or too oily after 30 minutes, it is important to readjust the dosage of the two formulas.
Dry skin type: Dry skin is used to describe a skin that produces less sebum than normal skin. As a result of a lack of sebum, dry skin lacks the lipids (oils) that it needs to retain moisture and build a protective shield against external factors. Corpa Flora recommends using DUOS right after the cleansing step by applying into your palm 1 full pump of facial oil and 1/2 a pump of hydration enhancer serum. Rub your hands together and apply to the face, neck and décolleté. If the skin is too dry or too oily after 30 minutes, it is important to readjust the dosage of the two formulas.
Oily skin types: Oily skin is characterised by enlarged and clearly visible pores, a glossy shine, thicker skin prone to blackheads and whiteheads, as well as varying forms of acne. Corpa Flora recommends using the DUOS right after the cleansing step by applying into your palm only a few drops of facial oil with 1 full pump of hydration enhancer serum. Rub hands together and apply to your face, neck and décolleté. If your skin is still oily 30 minutes after applying your DUO facial oil/hydration enhancer serum, you're using way too much facial oil, and you should readjust the dosages according to your own skin's needs.
