I’d like to share my personal whitening routine for a dull complexion.

Recently, I have been closely examining the ratio of niacinamide and vitamin C derivatives to structure my own systematic whitening routine. In particular, after cleansing in the evening, I follow a routine that involves layering a gentle vitamin ingredient with a high-concentration moisturizer; I often lose track of time analyzing the mechanism by which these ingredients create synergy to purify my complexion. I am also continuously observing whitening routines that combine AHA or LHA at very low concentrations to normalize the skin's turnover cycle—rather than simply reapplying functional products—as these seem to show significant data values ​​regarding the alleviation of pigmentation. I am very curious to know if you also have an ingredient combination you stick to to regain your skin's natural radiance! Since I am very curious about ingredients, could you share a little bit of your know-how with me?
