I recueved this product for free from gopicky and the skin house in exchange for my honest opinion.Since using this serum, I have noticed a difference in the appearance of my fine lines and wrinkles. They have become less noticeable and my skin looks smoother and more youthful. I appreciate that this serum is formulated with natural ingredients, including niacinamide and adenosine, which are known to be effective in improving skin texture and reducing the signs of aging.
