Round Lab Birch Juice Moisturizing Sun Stick SPF50+ PA++++ — a sunscreen stick designed for sensitive skin. It hydrates, softens, and provides reliable protection against UVA and UVB rays, helping prevent sunburn, pigmentation, and photoaging while maintaining skin firmness and smoothness.
The product provides a refreshing, cooling effect and soothes the skin after prolonged sun exposure. Its compact size makes it perfect for on-the-go reapplication.
The stick has a lightweight texture that does not leave stickiness or heaviness, even when layered, and is suitable for use under makeup.
