Birch tree moisture serum

The product I'm introducing this week on 'Purchased with My Own Money' is the Round Lab Birch Tree Hydration Serum. This is a serum I'm already on my second bottle of!

Round Lab Birch Hydration Serum has a slightly runny, watery texture, making it ideal for those who dislike sticky or heavy products. It also leaves a fresh and pleasant feeling after application.
