- What is in the TIRTIR 5 Actives Power Serums Kit?
- Five 10ml serums, each centered on a different active, including PHA, centella asiatica, niacinamide and vitamin C, plus a day serum.
- Can I use all five serums together?
- Better to rotate them. Layer one or two actives per routine and keep vitamin C and PHA use moderate to avoid irritation.
- Is it good for sensitive skin?
- The centella serum is the gentlest of the set. Patch test the vitamin C and PHA serums first, since acids and strong antioxidants can sting.
- How long does each 10ml bottle last?
- With once-daily use, expect a few weeks per bottle. Twice-daily use empties them faster.
- Does it replace a moisturizer?
- No. These are treatment serums; follow with a moisturizer and sunscreen, especially when using the vitamin C or PHA.
