What is Retinol?
Derived from vitamin A, retinol is part of the retinoid family. Discovered in 1931 in mackerel liver oil, retinol was not synthesised until 16 years later. Initially praised for its ability to reduce skin eruptions and acne scars, it also presents itself as a key ingredient in combating signs of ageing: loss of firmness, wrinkles and fine lines, pigmentation spots.
However, this high efficiency is accompanied by a recognised potential for irritation. The retinol can indeed cause redness and skin discomfort in individuals with sensitive or even atopic skin. In response to this, the European regulation has limited its concentration in non-rinse cosmetic products to 0.3%.
As a precaution,theuse of retinol is not recommended for pregnant and/or breastfeeding women. Since retinol is sensitive to light and can increase skin sensitivity when exposed to UV rays, it is preferred to use it in the evening for greater effectiveness. The following morning, a sunscreen suitable for one's skin type should be applied.
Benefit No. 1: A regenerative action on wrinkles.
Skin ageing is a degenerative process caused by internal biological factors (such as a decrease in collagen and hyaluronic acid levels) and external factors (pollution, UV rays, stress, smoking, etc.). It manifests itself through the emergence of irregularities on the skin's surface, such as wrinkles, pigmentation spots or even areas of sagging.
Retinol is recognised for its ability toboost the production of collagen and elastinfor smoother and more elastic skin. Furthermore, retinol possessesantioxidant properties. It prevents the appearance of ageing signs by neutralising free radicals. As a reminder, these are highly reactive molecules generated by various factors (stress, pollution, smoking...) that degrade the proteins and healthy cells of the skin, accelerating its ageing.
Benefit No. 2: Combatting blemishes and excess sebum.
When applied topically, retinol is metabolised into retinal and then intoretinoic acid, a key compound for caring for combination to oily skin, whether or not it has blemishes. The keratolytic action of retinol helps to remove dead cells present on the skin's surface, as it stimulates cell renewal. Pores are unclogged and the skin texture is refined, thus preventing the appearance of blackheads and/or comedones. Moreover, thanks to its brightening properties, retinol reduces the marks left by blemishes.
Benefit No. 3: Diminishing the appearance of brown spots.
The appearance of brown spots is linked to the ageing of the skin and/or exposure to external aggressions such as pollution and UV rays. As a reminder, hyperpigmentation is defined as a disruption in the pigmentation process: the melanin, pigment responsible for the natural colouring of the skin, is overproduced in certain areas which leads to the appearance of brown, red or pink spots that can sometimes be unsightly. Retinol regulates melanocytes and reduces the intensity of pigmented spots on the skin surface.

To combat skin ageing and prevent skin sagging, the wrinkle & fine lines serum contains 0.3% retinol. It is formulated with 99% natural origin ingredients. It is particularly suitable for mature skin. We advise against its use on sensitive and reactive skin.
The neck and décolletage serum is composed of retinol (0.2%) andborage oil, known for its firming properties. This treatment smooths the skin of the neck and décolletage. It can also be used locally on other parts of the body.
Our firming face cream with 0.2% retinol andtsubaki oil is enriched with tightening agents to combat the appearance of wrinkles and make the skin more plump. It stimulates the production of collagen and elastin fibres to prevent signs of skin ageing.
The firming toner contains 0.1% retinol and Damask rose extract. It is applied after skin cleansing, to rebalance the skin's pH and delay the appearance of wrinkles. It is composed of 99% natural origin ingredients.
The wrinkle and blemish serum combines the densifying action of retinol (0.3%) with the anti-bacterial action of bakuchiol (1%) to reduce the appearance of wrinkles and correct blemishes. Synthesised by endemic Australian plants, the plant polypeptides it contains are capable of working in synergy with retinol to promote the synthesis of type I collagen. They thus help to reduce the depth of wrinkles and densify the skin. These peptides also contribute to maintaining a thick epidermis, which plays its role as a shield against the external environment.
