Retinoids and Skin function

Retinoids and Skin function

04/06/2019 Off By Dorthy Rand

The term skin “normaliser” is used because most natural functions of the skin rely on the influence of retinoids, in one form or another.

As skin cells develop, they change structurally, ageing and hardening as they move further away from the deep (basal) layers and upwards towards the epidermis. This process is called Keratinisation.

Retinoids slow down and suppress the rate of differentiation and movement of these skin cells.

Fibroblasts, which are the collagen producing cells within the skin, have retinoid receptors, thereby allowing retinoids to aid in increasing collagen production by stimulating these cells.

There is evidence that retinoic acid can inhibit production of certain enzymes produced as a result of exposure to UV. These enzymes are linked to degradation of collagen, so it can be said that retinoic acid reduces photo-ageing.

Retinoids decrease the production of sebaceous liquid so are therefore ideal for the ipl treatment brisbane of oily skin conditions and acne.

Retinoids help with the shedding of dead skin cells from the epidermis, so must always be used in conjunction with the correct SPF.

Environ Vitamin A range

The Environ range of creams are formulated using mainly retinyl palmitate which is a mild, non irritating, easily absorbable form of retinoic acid.

They begin with low concentrations, thereby allowing the gradual build up of Retinol Binding Proteins. This also helps to reduce skin reactions, whilst allowing the strength to build slowly over a period of time.

There are low oil formulations for oily and acne prone skin.

The creams are manufactured using no fragrances and no preservatives. All anti-oxidants contained in the creams are there to have a direct influence on the skin.

The A creams also contain beta-carotene, vitamins C and E and provitamin B5, all excellent anti-oxidants with strong free radical scavenging properties.

All creams are formulated in a light non-greasy consistency and can be used around the eye area as well as the face and neck. This is an unusual bonus as most skin creams are not suitable for the delicate eye area.

As well as a full complement of facial products, the Environ range incorporates superb body products.

Vitamin C -the skin brightener and firmer

Vitamin C is water soluble and therefore is excreted in urine within a couple of hours of ingestion. Like all vitamins taken orally, either in the diet or as a food supplement, very little reaches the skin.

Vitamin C is not stored in the body and is not synthesised by the body.

Vitamin C in it’s natural form is Ascorbic acid which is highly irritating to the skin.

Functions of Vitamin C

Plays an important role in the synthesis of collagen.

Reduces pigmentation by inhibiting the production of melanin

Has a strong anti-enzyme activity- inhibits collagenase, elastase and hyaluronidase. These are all collagen destroying enzymes.

Has anti-inflammatory properties and soothes skin.

Maintains capillary integrity so helps to reduce bruising.

It has photoprotective properties.

Helps to enhance levels of Vitamin E, required for skin healing.

Helps with iron metabolism.

Vitamin C is found in citrus fruits, hip berries, paprika, fresh tea leaves.
