Over time, hormonal changes, post-acne hyperpigmentation, skin aging, and repeated sun exposure promote the appearance of small pigmentation irregularities on the skin.
To effectively combat this hyperpigmentation and restore a radiant complexion, Graine de Pastel research has developed a major innovation: an exclusive dark spot-correcting patent, drawing its strength from pastel bioflavonoids.
But how does this patented active ingredient work? A deep dive into plant science and the biology of your skin.
The origin of pigmentation spots: the mechanism of melanogenesis
The color of human skin is primarily determined by the nature and concentration of a natural pigment: melanin. It is synthesized by specific cells called melanocytes, located in the basal layer of the epidermis.
This pigment production process, known as "melanogenesis," is a complex chain regulated by an essential enzyme: tyrosinase. This enzyme orchestrates the initial stages of transformation, converting an amino acid (tyrosine) into melanin. Once produced, melanin is transferred to the cells on the skin's surface (keratinocytes).
However, when this mechanism becomes disrupted or altered, for example by sun exposure, melanin accumulates abnormally and excessively on the skin's surface. This accumulation creates unsightly dark spots (actinic lentigines, sunspots, melasma, or age spots), making the complexion uneven.
Graine de Pastel Innovation: A unique plant-based synergy
To naturally correct these pigmentation disorders, our laboratory developed and patented a unique oil-based composition. This patent is based on the combination of two lipophilic botanical extracts:
- A plant extract derived from the leaves of our signature plant, Isatis tinctoria (pastel), whose seeds are naturally very rich in polyphenols.
- An extract derived from rosehip berries (Rosa canina, also known as rosehip), specifically selected for their richness in ellagic acid.
These active ingredients (the famous bioflavonoids) are obtained through a very short, high-temperature eco-extraction process, carried out directly in exceptional vegetable oils, such as virgin pastel seed oil and rapeseed oil.
How does this patented active ingredient work on your skin?
The effectiveness of our patented dark spot-correcting active ingredient is based on precise biological inhibition and a synergy of ingredients:
- Tyrosinase inhibition: The active ingredient acts directly at the source of hyperpigmentation by inhibiting tyrosinase activity. By slowing this enzyme's activity, melanin synthesis is blocked, preventing the formation of new spots.
- A proven synergistic effect: Studies conducted by our laboratory have demonstrated that the combination of pastel and rosehip extracts has remarkable inhibitory properties. The result is a true synergy: tyrosinase inhibition (and therefore melanin inhibition) is more than 20% greater than the sum of the effects of each extract used separately.
Visible results for an even complexion
Thanks to this highly precise mechanism of action, found at the heart of our Anti-Dark Spot Correcting Serum, our patented active ingredient delivers comprehensive results:
- Corrective action: It brightens the skin, effectively reduces pigmentation, and visibly diminishes pigmentation spots.
- Preventive action: It helps prevent the appearance of future dyschromia (pigmentation disorders) by regulating melanin production from within.
- Radiance and evenness: Day after day, it improves the evenness of the complexion, giving the skin a luminous, uniform appearance and a natural glow.
Finally, because respecting the skin is at the heart of our commitments, the oil-based vehicle of this patent offers excellent skin tolerance: it is not phototoxic, ensuring safe daily use over an extended period.
Applying sunscreen after the serum is essential: it protects the skin and prevents the appearance of new pigmentation spots.
