what niacinimide serum are you using? other options also include TXA

a good serum ive found for hyperpigmentation is :

https://www.yesstyle.com/en/anua-ni...um-2024-version-30ml/info.html/pid.1132942898
(they rebranded but it should be the same formulation)

txa and niacinimide are effective together:

furthermore if your really want to reduce hyperpigmentation dermaneedling is much more effective with products such as:

https://www.drpenskincare.com/colle...42-056b-4432-8c80-5df939739997.collection_1.1

however tretinoin or any retinoid such as adapelene are much more effective, BHA will do virtually nothing, and im not sure what your referring to when you say collagen but collagen supplements are unresearched and show minimal effects, furthermore topical collagen is useless. vitamin c can work, however vitamin c serums are irritating and have a very short shelf life, instead using absorbic acid which is the more stable chemical formulation of vitamin c
