advice on Alpha Arbutin & Azelaic acid

Azelaic like retinol promotes skin renewal and If I'm not mistaken it's commonly prescribed by dermatologist for people with rosacea so it's more of a drug than cosmetic. Arbutin, on the other hand, is a good skin brightener. It depends on what kind of skin concern you have in choosing whether vit c, retinol, etc. Some are comfortable using arbutin but not vitamin c, vice versa. It's probably better to use one active at a time so your skin wouldn't be overwhelmed it will end up irritated. Tho, tiam b3 already has niacinamide in it with arbutin and people are loving it. On my previous discussion regarding HG Brightening Products most people recommend Tiam B3.

Treating PIH is hard. As you need to stop different pathways that form pigment. The UVB rays Inflammation and trauma (pimple) (chaffing) tyrosinase producing cells tyrosinase excacerbation so its not just one product that solves all thats why lots of people struggle with fading PIH. So the PIH combo I could for me is a multi products one that target this. Light exfoliation with AHA once a week. Niacinamide+VitC+Arbutin+spf has been my sweet spot I have tried each separately, then slowly adding one at a time observe how my skin likes it before adding more.

Thank you for starting this discussion! ❤️ I have redness and PIH so I’ve always wondered what the difference is
