This winter, the answer to preserving beautiful skin is something we all already know. Gently removing harmful substances without irritation, replenishing moisture and nutrients, and carefully following protective steps that allow active ingredients to remain on the skin longer—there is no formula more powerful than mastering the basics. Winter is the perfect season for intensive care ingredients that target concerns such as dark spots, melanin, and fine lines. During this dry period, the stratum corneum becomes thinner, allowing low-molecular-weight, water-soluble ingredients to penetrate more effectively, while lower ultraviolet levels reduce the risk of irritation. Moreover, with longer nights and increased time spent indoors, winter makes it easier to fall asleep naturally during the critical hours between 10 p.m. and 2 a.m., when skin-regenerating hormones reach their peak. As cellular renewal and collagen synthesis are most active during this time, skincare efficacy is maximized. Applying active treatments while the skin remains slightly damp—before toner and essence are fully absorbed—enhances penetration. Rather than applying a large amount at once, layering small quantities multiple times proves far more effective. Within three minutes after showering, the skin barrier becomes more pliable and highly receptive to moisture—making this moment a true golden window that should never be missed. fter gently pressing the face with a towel to remove about 70 percent of surface moisture, it is ideal to apply a moisturizer. Overly watery toners, when layered repeatedly, may in fact accelerate moisture loss depending on the formulation; therefore, during winter, a hydrating toner with moderate viscosity is more effective. If you have showered in hot water, dilated capillaries can hasten dehydration, so finishing cleansing with cool water is recommended. As areas near indoor heating systems often fall below 30 percent humidity and become extremely dry, it is advantageous to begin the first step of skincare near a humidifier or in a bathroom where humidity is maintained (Hyangjang, p. 688). |
