How are you all managing your complexion these days? The weather's cold and dry, and my skin has been looking duller and more flaky than usual, which has been a concern. I impulsively bought a bunch of products during the All Young sale, so I looked at the ingredient lists and designed my own optimal whitening routine. The core of my whitening routine is focusing on antioxidant care in the evening. Vitamin C is prone to oxidation, so I use it mainly at night when I'm away from UV rays. I layer it with hyaluronic acid, which replenishes moisture, to reduce irritation while increasing the absorption of the active ingredients. Since heaters can easily disrupt the oil-water balance, I'm also meticulously applying a barrier cream. After about ten days of this whitening routine, my dull complexion has definitely brightened. What ingredients do you focus on during this cold winter? If anyone uses high-dose vitamin products like I do, I'd love to hear your tips. This is something I realized while analyzing the ingredient mix this time. It seems that moisturizing is more important than simple whitening to properly create a glow!
