Description
The ROUND LAB Birch Juice Moisturizing Lip Balm 20g is a hydrating lip balm designed to give lips a plump, glassy glow while helping relieve dryness and flakiness. Infused with birch sap, glyceryl glucoside and a blend of five natural oils, it creates a moist “vita” moisture barrier for lips that frequently face makeup, cleansing and daily UV exposure. This formula is suitable for anyone seeking soft, comfortable lips with a healthy-looking shine.
Key Features
- Moisturizing lip balm that delivers a plump, glass-like glow to the lips.
- Contains moisture-rich birch sap from Inje, known for its amino acids and minerals that help hydrate dry skin.
- Features glyceryl glucoside, inspired by the resilience of the resurrection plant, to support the skin’s internal moisture pathways.
- Helps activate aquaporin water channels in the skin to promote effective moisture absorption.
- Creates a soft “vita moisture barrier” to improve the look of dull lips and keep them feeling supple.
- Formulated with five natural oils for long-lasting moisturizing shine: olive oil, sweet almond oil, argan kernel oil, macadamia seed oil and jojoba seed oil.

- In a human application test on 23 adult women, measured lip moisture increased from 39.57 to 50.17 after a single use (an increase of 26.78%).
- Tested for improvements in both lip moisture and lip keratin condition after use.

Bu dudak balsamını sevdim. Dokusu hafif ama oldukça nemlendiriyor. Uzun süre etkili kalıyor, çatlakları hemen giderdi. Günde birkaç kez kullanmak yeterli oldu.
