A whitening routine to help with a dull complexion

Because of the winter heating, the indoor air has become so dry that my complexion has looked much duller than usual. I've even lost my lip balm, so my lips are parched and flaky. My overall skin tone has darkened, so I realized the urgent need for a systematic whitening routine.

In fact, whitening isn't simply about whitening. It involves blocking melanin formation and precisely calculating keratin turnover. The key to my whitening routine is adjusting the ratio of niacinamide and vitamin C derivatives.

We analyzed the optimal environment for effective ingredients to penetrate while minimizing irritation. Especially in the dry winter months, when moisture retention decreases, the absorption rate of whitening ingredients also decreases. Therefore, we concluded that a whitening routine that strengthens the skin's lipid barrier, rather than simply applying additional products, is the only way to fundamentally improve complexion. To improve skin condition, we must meticulously refine our routine based on ingredient data.
