Although it contains a 150% higher concentration of vitamin C, it's gentle and non-irritating. It's also almost fragrance-free, making it easy to use. It comes in single-use individual packets, so it's fresh and refreshing every day. It's fast-acting, absorbs deeply, and lasts for a long time, and it completely transformed my midwinter dry skin! It even feels completely different. Before I started using it, I was struggling with dry skin, but this product moisturizes without irritation, and my foundation application has completely changed. It even covers pores, so it's like my worries were a lie! I later found out that this product alone is enough after applying lotion, and it made sense. It serves five purposes: serum, oil, emulsion, vitamin pack, and massage gel, making it a valuable ally for those raising small children.
