Pores and skin barrier perform
It was recognised solely in the previous few many years that the stratum corneum – the uppermost layer of the pores and skin – contributes on to sure organic processes that preserve the pores and skin wholesome. Its perform just isn’t solely to guard, but additionally to detect and adapt to exterior elements (resembling irritants, allergens, microbes or climatic modifications).
We all know now that this uppermost epidermal layer just isn’t merely an amorphous mass of keratin fibres and a few lipids. Its “useless cells” have an vital perform in managing organic roles, primarily due to their highly-organised construction.
Pores and skin barrier perform is outlined by the lipids discovered within the stratum corneum extracellular house (additionally known as the extracellular matrix). Over 50% of those lipids are composed of ceramides, however there are additionally fatty acids and ldl cholesterol. Collectively, all three varieties of lipid create a critically-balanced molecular ratio.
If this turns into imbalanced, the barrier conformity turns into affected and even impaired. You will need to say that disruption of the pores and skin’s acidic mantle results in a discount of lipid-processing enzymes which are concerned in sustaining the right lipid ratio.

Ceramides and the pores and skin barrier
Within the human pores and skin (stratum corneum), there are 9 subclasses of ceramides which were recognized, and so they differ from one another with respect to their structural base. Ceramides numbers one and 4 have an distinctive molecular construction of linoleic acid linked to omega hydroxy fatty acid. Pores and skin tissue ranges of those two parts is decreased considerably in pores and skin circumstances resembling atopic dermatitis and are additionally strongly affected by ageing.
Due to this fact, skincare merchandise which are capable of replenish the “lacking” lipids (e.g. ceramides) within the pores and skin could also be thought-about barrier repairing, totally on account of their means to restructure and enhance the integrity of the stratum corneum barrier.
Pure and artificial ceramides in skincare
Ceramides bear completely different names and might be synthesised or derived from completely different sources. Plant-derived ceramides can provide our skincare environment friendly and sustainable options to boost the pores and skin’s barrier. Rice, wheat and oats are the primary selection of crops for ceramide extraction, however maize, soy, potato and konjac have been used successfully too.
About our ceramide cream
Water-in-oil (W/O) emulsions are varieties of skincare merchandise identified for his or her additional moisturising and nourishing properties. W/O emulsions have been confirmed to additionally promote pores and skin barrier regeneration processes, particularly when they’re formulated on the appropriate pH. By enriching the W/O cream with ceramides, we must always be capable of set off restructuring and regenerative processes within the pores and skin that can lead to higher integrity and performance of the pores and skin barrier.
Our formulation makes use of a complicated emulsifier that’s designed to allow water-and-oil fusion through the use of patented expertise. The emulsifier – PolyAquol™-VO4 – is totally pure and allows the creation of cold-process emulsions. The ultimate product provides distinctive stability, and its texture provides it a tremendous sensory profile.
Key components
Emulsifier – we have now chosen a particular emulsifier best for creating water-in-oil emulsions. You will need to comply with all utilization directions to your chosen water-in-oil emulsifier.
Salt/Sodium chloride – this can be a essential stabilising ingredient for W/O emulsions.
Treasured plant oils – we have now chosen particular oils as emollients that comprise a novel mixture of fatty acids to assist nourish the pores and skin. Plum seed oil is a fragile oil obtained from the kernel of plums and is a invaluable supply of omega fatty acids and phytosterols. Cranberry seed oil accommodates important fatty acids in addition to phospholipids and phytosterols. Pomegranate seed oil accommodates important fatty acids and is wealthy in polyphenols that present wonderful antioxidant and regenerative properties.
AvenaPlex – this can be a proprietary lipid advanced obtained by ethanol extraction from oat kernels. This extract is wealthy in pure sterols, ceramides and fatty acids. It accommodates lively compounds that assist restore the integrity of the pores and skin barrier.
