An anti-aging serum with a silky liquid texture that targets fine lines and loss of firmness. It absorbs quickly to deliver its active ingredients, working best when layered under a moisturizer or blended into a daily cream. It’s a reliable, no-fuss step for addressing signs of aging without adding bulk to a routine. The finish is weightless, so it won't interfere with other products or leave a greasy residue.
