The Rainbow Algae
As consumer expectations continue to evolve, skincare is no longer focused solely on whitening. Today’s market increasingly favors solutions that promote healthy-looking, radiant, and even-toned skin.
This shift has encouraged cosmetic researchers to explore next-generation brightening ingredients that work beyond traditional approaches. Among these emerging actives, Cybright® G has gained significant attention for its unique origin and innovative mechanism of action.
Derived from Rainbow Algae, Cybright® G represents a new opportunity for brands seeking to develop premium brightening skincare products with a compelling scientific story.
Inspired by the Ocean: The Story Behind Rainbow Algae
Cybright® G is derived from Cystoseira tamariscifolia, commonly known as Rainbow Algae.
Native to the coastal waters of Brittany, France, this marine algae is known for its iridescent appearance, reflecting multiple colors under sunlight.
Living in a challenging marine environment, Rainbow Algae has developed unique biological defense mechanisms to adapt to changing light conditions. These characteristics inspired the development of Cybright® G as a modern cosmetic active ingredient.
Mechanism of Action
Cybright® G works through three key stages—before, during, and after melanin synthesis—to effectively reduce overall pigment formation.
Step 1: Before Melanin Synthesis – In Keratinocytes
Cybright® G helps prevent melanin formation at the signaling stage through two main actions:
- Reduces the synthesis of α‑MSH, the key hormone that triggers melanin production.
- Promotes the production of a competitive molecule that blocks α‑MSH from binding to its receptor, preventing the activation of the pigmentation process.
Step 2: During Melanin Synthesis – In Melanocytes
Cybright® G targets active melanocytes to suppress melanin production:
- Inhibits the maturation of melanosomes (Melanosomes can only produce melanin after they reach full maturity.)
- Activates an inhibitory factor that suppresses tyrosinase synthesis, the enzyme responsible for melanin production.
Step 3: After Melanin Synthesis – In Keratinocytes
Cybright® G helps reduce visible pigmentation by controlling melanin distribution and promoting its breakdown:
- Decreases factors involved in melanosome uptake by keratinocytes, reducing pigment accumulation.
- Activates Cathepsin L2 (CSTL2), an enzyme that contributes to the degradation of melanosomes inside keratinocytes.
