As the world’s first to extract this natural form of vitamin A derivative, it offers safety and greater stability compared to Retinol.

1. This is the most effective vitamin A derivative because Retinal can naturally convert to Retinoic Acid in a single enzymatic process on the skin, making it faster and more effective than Retinol.

2. It has high safety standards (additional details available in the Safety Profile file). Irritation from vitamin A usually occurs due to excessive Retinoic Acid on the skin. Retinaturel and RetinalO5, derived naturally and formulated at an optimal dosage range (1-4%) for effectiveness, minimize excessive Retinoic Acid exposure, avoiding toxic allergic reactions or photosensitivity. Safe for long-term and daytime use (see Safety Profile, page 6 on local toxic effects, irritation, and sensitivity).

3. This natural derivative is more stable than synthetic forms of vitamin A, including Retinol. Retinal is extracted using advanced technology from the purple membrane of the microorganism HALOARCHAEA, one of Earth’s oldest organisms, which thrives in extreme environments. This ensures higher purity and stability than synthetic vitamin A derivatives, including Retinol. Customer use and stability tests across countries have shown no stability issues.

4. Volunteer testing shows enhanced skin firmness, wrinkle reduction, acne reduction (in vivo), and improvements in dry, dull skin and redness from conditions like rosacea. Retinaturel’s anti-wrinkle effects are well-documented in these studies.
