Retinol and skin aging.

When applied topically, retinol is a compound that is metabolized into retinoic acid, the active form of Vitamin A. It possesses excellent keratolytic properties, making it a prime choice for unclogging pores and preventing blemishes. It is also widely acclaimed for combating the appearance of wrinkles caused by photoaging of the skin.

A Brief History of Retinol in Cosmetics.

Retinol belongs to the family of retinoids, which are derivatives of vitamin A, such as retinoic acid and retinal. The retinol molecule was first isolated in 1931 by Swiss chemist Paul KARRER, from mackerel liver oil. The first study using tretinoin (or all-trans retinoic acid) to treat acne was published in 1943. The effectiveness of this organic compound on signs of aging was demonstrated in the 1980s by American dermatologist Albert KLIGMAN. However, tretinoin is one of the substances banned in cosmetic products according to the European Regulation due to its irritating potential. This active ingredient is only available on prescription to treat severe acne. Studies have shown better skin tolerance for retinol, compared to tretinoin. The European Cosmetic Regulation thus authorizes it up to 0.3% in a non-rinsed product. When applied to the skin, retinol is oxidized into retinal and then metabolized into retinoic acid, its active form capable of effectively combating photo-aging of the skin and thus smoothing the skin texture.

Retinol, an effective ingredient for combating skin aging.

Retinol operates on multiple levels to prevent wrinkles or reduce those already present on the skin's surface. Many of its tissue effects are mediated by its interaction with cellular receptors, such as the cellular retinoic acid-binding protein (CRABP) of types I and II and the cellular retinol-binding protein. Retinol and retinoids in general will act on several levels.

  • Increasing the thickness of the epidermis.

    With age, the epidermis thins and both cellular renewal and keratinocyte proliferation slow down. This loss of skin tissue promotes the appearance of wrinkles on the skin's surface. Retinol acts by stimulating the proliferation of keratinocytes.

  • Limiting the degradation of collagen and elastin.

    These two proteins are key components of the connective tissue that makes up the dermis. They strengthen the skin and increase its elasticity and firmness. Unfortunately, over time, they are degraded by enzymes known asmatrix metalloproteinases (MMP), and more specifically collagenase and elastase. Topical application of retinol inhibits the activity of these enzymes, preventing them from causing harm. Additionally, it stimulates the synthesis of type 1 collagen in the dermis.

  • Blocking the damage caused by free radicals.

    Free radicals are highly reactive, unstable molecules that degrade healthy cells and proteins in the body, accelerating its aging process. They are generated by a variety of factors, the most common being pollution, UV rays, and cigarette smoke. Retinol neutralizes these molecules, thereby blocking their harmful effects on the skin.

  • Combating pigmentation spots.

    The appearance of brown spots is linked to the aging 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 coloration 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's surface.

Our retinol-based products.

To combat skin aging 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 décolleté serum is composed of retinol (0.2%) and borage oil, known for its firming properties. This treatment smooths the skin of the neck and décolleté. It can also be used locally on other parts of the body.

Our firming face cream with 0.2% retinol and tsubaki 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 to prevent signs of skin aging.

The Firming Tonic Lotion 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. Synthesized 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.
