- How is this different from the Sturm Hyaluronic Serum?
- The Hyaluronic Serum is a single hydrating formula. The Dual Serum adds a second chamber with ceramides and peptides aimed at firmness and barrier repair, so it is richer and more targeted at anti-aging.
- How do I use it?
- Press the pump to mix both chambers, then apply to clean skin morning and evening before moisturizer. It layers under sunscreen and makeup.
- Is it suitable for oily or acne-prone skin?
- It is aimed at normal to dry skin. The emulsion is fairly rich, so oily or breakout-prone skin may prefer a lighter serum.
- How long until I see results?
- Hydration is immediate. Firming and line-smoothing effects are gradual, and most users report changes over several weeks of consistent use.
- Is it fragrance-free?
- Yes, the formula is fragrance-free, which helps with sensitive skin. Patch test if you react easily to peptides or plant extracts.
- What is in the box?
- One 1.69 oz dual-chamber pump bottle of serum. No applicator or travel size is included.
