Overview
A shopper with oily or combination skin gets a clear, lightweight serum built around niacinamide at a high strength with zinc PCA. Hyaluronic acid and aloe leaf extract add hydration, and the texture is described as non-sticky.
The strength of niacinamide and the zinc pairing make this a focused option for shine control and visible pores. The limitation is thin listing detail: some fields are contradictory, such as a fair skin tone and UV protection use, so rely on the label.
Who it's for
Someone fighting shine and visible pores who layers sunscreen and makeup will find the quick-absorbing, non-sticky texture practical. People with dry or reactive skin may find a high niacinamide strength too active, and anyone wanting a sunscreen should buy one separately.
Pros and cons
- Niacinamide with zinc PCA for shine control
- Hyaluronic acid for hydration
- Non-sticky finish under makeup
- Long free-of list incl. alcohol and oil
- No usage directions listed
- Some listing fields contradict each other
- Not a sunscreen despite a UV use field
Performance notes
Niacinamide and zinc PCA act on oil balance and the look of pores, and the effect builds over weeks of daily use. A clear, water-light serum texture absorbs quickly and layers under makeup and sunscreen. Strength matters, so introducing it gradually on reactive skin makes sense.
