Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Acetyl Hexapeptide-8, commonly known as Argireline, is a popular peptide in skincare. It’s often referred to as a “Botox-like” ingredient because it helps reduce muscle movement.
By relaxing these micro-movements, Argireline may help minimize the appearance of fine lines and wrinkles. That said, it’s not as powerful as Botox, and research on its long-term effectiveness is still limited.
Beyond smoothing, Argireline may also support collagen production. Collagen is the protein that helps keep your skin firm, bouncy, and well-hydrated by strengthening the skin barrier.
So while Argireline isn’t a miracle fix, it can be a helpful addition to a routine focused on both prevention and skin health.
