📋 目次
1What concentration of vitamin C is most effective in a 30ml serum?
Look for 10-20% L-ascorbic acid for visible brightening and antioxidant benefits. Lower concentrations may not work well, while higher ones can irritate sensitive skin. Start with 10% to build tolerance if you're new to vitamin C.
2Should I choose a serum with vitamin C or a vitamin C + E + ferulic acid combo?
The combo of C, E, and ferulic acid is more potent for UV protection and anti-aging, but it's usually more expensive. A standalone C serum is fine for basic brightening and is often more affordable for daily use in a 30ml size.
3How long does a 30ml vitamin C serum typically last?
A 30ml bottle usually lasts 4-6 weeks with daily use, depending on how much you apply. If you use it morning and night, it may only last 3-4 weeks. Consider this when comparing value between brands and sizes.
4Does the packaging matter for a vitamin C serum?
Yes — vitamin C degrades in light and air. Look for dark, airtight bottles with droppers or pumps to keep the formula stable. Clear glass or open jars can reduce potency and effectiveness over time, even in a 30ml size.
5Is it worth paying more for a 30ml vitamin C serum with hyaluronic acid?
Yes, if you have dry or sensitive skin — hyaluronic acid boosts hydration and helps vitamin C absorb better. For oily or acne-prone skin, a basic C serum may be enough. Check the full ingredient list to avoid unnecessary additives.
