Effective for Fine Lines [SEP] I like these so much that I purchased more.<br />This German skin care line is one of my favorites because of the quality of ingredients and the effectiveness of the product.<br />No irritation, even around my sensitive eyes.<br />The serum preps your skin for the next step of skin care, such as moisturizer. Your day or night cream sinks into your skin better, creating a noticeable difference in fine lines.
