I have been using the French Farmacie Solstice C Serum daily for 4 months now and absolutely love it! I have seen a noticeable difference in the texture on my chin where I’m prone to acne scarring and dark spots. My skin is now smoother and brighter and I’ve seen similar results on my chest where I have some sun damage/sun spots. I’m really impressed with this product and pair it with the Alchemy Serum at night. I tend to have sensitive skin and these have been dream products, no irritation, just beautiful, soft skin. HIGHLY recommend both!

I was pleasantly surprised by this serum, such a silky application and absorbed beautifully into my dry skin. Even when followed up with a heavy moisturizer (winter skin) the serum still gave off a dewy glow. It’s a wonderfully luxurious addition to my routine!

Absolutely love this vit C serum! The consistency is so light and absorbes quickly. My skin feels hydrated and has the best glow. I will absolutely purchase this product again and recommend to others.
