Which is better for dark spots: alpha arbutin or niacinamide?

Both are effective but work differently. Alpha arbutin directly inhibits tyrosinase (the enzyme that produces melanin) — making it more targeted for specific dark spots. Niacinamide inhibits melanin transfer and provides broader skin benefits. For maximum results, use both: alpha arbutin in the evening and niacinamide morning and evening.

Can I use alpha arbutin and niacinamide together?

Yes. Alpha arbutin and niacinamide are compatible and work through complementary mechanisms. They can be used in the same routine or at different times of day. A common approach is to use both in the evening: apply niacinamide first, then alpha arbutin.

How long does alpha arbutin take to work on dark spots?

Alpha arbutin typically shows early improvement in 4-6 weeks and significant fading of dark spots in 8-12 weeks of consistent daily use. Daily SPF 50 is essential to protect progress and prevent new pigmentation.

Is alpha arbutin or niacinamide better for melasma?

Alpha arbutin is generally more effective for melasma because it directly inhibits tyrosinase, the primary enzyme involved in melasma's melanin overproduction. However, using both together provides the most comprehensive approach to melasma treatment.
