Overview
QRxLabs S-HDRO1-2 is a hyaluronic acid serum boosted with vitamin B5, sold in a 2 fluid ounce bottle that is unscented and positioned for all skin types rather than one specific skin concern.
Hyaluronic acid serums work by drawing moisture into the skin's surface, and pairing it with vitamin B5 (panthenol) is a common combination aimed at soothing alongside hydration. At 2 fluid ounces the bottle is larger than many serum offerings, which suits daily use over months.
- 2 fl oz serum
- Hyaluronic acid plus vitamin B5
- Unscented
- For all skin types
Who it's for
Anyone wanting a basic hydrating serum layer without added fragrance, across skin types since none is singled out.
Pros and cons
- Larger 2 fluid ounce size than many serums
- Simple two ingredient focus on hydration
- No stated actives beyond hyaluronic acid and vitamin B5
Performance notes
Hyaluronic acid can hold many times its weight in water, so a serum built around it functions mainly as a hydration layer applied before a moisturizer. Vitamin B5 is typically included to support the skin barrier alongside that hydration.
