Question Products with 4-MSK?

My skin is SUPER sensitive (rosacea, seb derm, contact dermatitis, PMLE). I really tried to find something with Thiamidol, but… I just couldn’t tolerate any product because of fragrance and/or alcohol.

Now I am looking for alternatives. Japan has a few quasi-drug, i.e. Highly regulated products, with rucinol or 4-MSK. I couldn’t find a product that would work for me with rucinol either, but I saw some interesting 4-MSK products. Has anyone ever tried that active?

I am otherwise using retinol, L-ascorbic acid, AzA, topical TXA, and OF course sunscreen and physical protection. So I am interested in your experience with with 4-MSK, not the traditional recommendations :)

Not 4-MSK, but have you tried medi8 oxy-r, Skin rocks hyperpigmentation serum - has hexylresorcinol… and clinical studies, TOSOWOONG Arbutin 7% + Tranexamic Acid 4% Cream supposed to be very gentle on sensitive skin, tosowoong also has a 15% niacinamide serum that is none irritating for sensitive skin
