The stratum corneum is the outermost layer of the skin. It acts as a protective barrier and helps to prevent the invasion of microorganisms and bacteria. However, with age or exposure to external factors, the stratum corneum may not completely shed after normal turnover, leading to a buildup of dead skin cells. This can result in rough, dull, and discolored skin, and may even contribute to various skin conditions. Therefore, exfoliation is an important step to achieve smoother and more radiant skin. However, it is easy to make mistakes during the exfoliation process, which can not only fail to produce the desired results but also affect the skin's whitening and health.
Pitfall 2: Anyone can exfoliate regardless of skin type
Many people mistakenly believe that exfoliation is simply about removing dirt and impurities from the skin. In reality, there are certain skin types that should avoid exfoliation, and some areas of the skin where exfoliation products should not be used. Let's delve into the nuances of exfoliation.
1. Skin types that should avoid exfoliation
(1) People with extremely dry skin or peeling skin should avoid exfoliation as it can exacerbate facial dehydration and worsen the peeling.
(2) People with pustules or inflamed acne should not exfoliate as it can increase the risk of bacterial infection in the wounds.
(3) Individuals with sensitive skin should not remove the stratum corneum, as their skin already has a thin protective barrier. Exfoliation can make the skin even more fragile.
(4) After undergoing skin rejuvenation treatments such as chemical peels or microdermabrasion, it is best not to use exfoliation products. If there are any wounds, cracks, moles, or skin lesions, it is also advisable to avoid exfoliation.
2. Skin types that should be cautious with exfoliation
Skin with a thin stratum corneum and visible redness should not undergo exfoliation. For skin with acne, special attention should be paid during exfoliation. If the acne is pus-filled or inflamed, exfoliation should be avoided.
3. Duration and intensity of exfoliation
There is no fixed duration or intensity for exfoliation. It can be adjusted based on personal preference. When exfoliating, gently massage the forehead in circular motions following the skin's texture, and gently rub the cheeks from bottom to top in circular motions. For the nose area, rub up and down along the contour. However, remember not to apply excessive force.
