The bi-phase formula is interesting—it’s a mix of oil and watery solution, but it blends effortlessly, leaving my skin feeling nourished and hydrated. It's light, absorbs quickly, and doesn’t feel greasy at all. The scent is very mild and pleasant, which I love. I’ve noticed an improvement in my skin tone in just a few weeks, and I’m excited to see more results as I continue using it. One of the best parts is that it’s free from parabens, phthalates, fragrance, mineral oil, and petrolatum, which makes it a great option for sensitive skin like mine. Highly recommend if you're looking for a gentle yet effective serum!
