Repurchased once.
Found that this was a good addition to my routine when my moisturizer wasn’t holding onto enough hydration during the hot summers. It’s lightweight, and works well with the birch toner. If you don’t apply to damp skin, it will feel drying over time. Debating on whether to repurchase again.
