Contains Retinol 0.6% + B3 Anti-Ageing Night Serum / Retinol 1% + B3 Anti-Ageing Night Serum. Why use one vitamin A product when you can use two?! For the ultimate health boost, pair retinyl palmitate (found in Skin Protein) and Retinol together to improve skin texture, reduce the appearance of fine lines and wrinkles, and enhance overall skin tone. While retinol is known for its more potent and immediate effects on skin renewal, retinyl palmitate provides a milder, sustained influence, making it an excellent choice for individuals who are new to retinoids or have sensitive skin. By combining these two forms of vitamin A, you can effectively address various skin concerns while minimizing the potential for irritation, allowing for a balanced and gentle approach to supporting skin health. As always, it's important to introduce new skincare ingredients gradually and monitor your skin's response to ensure that the combination of retinyl palmitate and retinol is well tolerated and beneficial for your individual skin needs.
