On the road to perfect skin quality, the health of the stratum corneum becomes the key. It is not only the first line of defense for the skin, but also the cornerstone of hydrated and translucent skin. This article will start from the function of the stratum corneum, explore the correct concepts and methods of exfoliation and keratin care, and recommend maintenance strategies suitable for various skin types to help you create stable and radiant skin.
1. The role and importance of the stratum corneum
The stratum corneum is the outermost layer of the skin. It is a natural barrier gradually formed by the bottom layer of the skin, responsible for protecting the skin from external irritation and moisture loss. A healthy stratum corneum can maintain the moisture balance and radiance of the skin. On the contrary, a damaged stratum corneum can easily cause dryness, sensitivity and even aging problems [1].
Therefore, the maintenance of the stratum corneum should not only focus on removing old and dead keratin, but also pay attention to its repair and nourishment to maintain its structural integrity and normal function.
2. Exfoliation: When should it be done? How to do it?
1. Necessity of exfoliation
As we age, the metabolism of our skin slows down, and the accumulation of dead skin cells causes dull and rough skin tone. Moderate exfoliation becomes necessary. However, healthy skin has its own natural metabolic capacity. Excessive exfoliation can damage the skin barrier, causing sensitivity and dryness[1][2].
2. Correct steps for exfoliation
- Makeup removal and cleansing: Use mild and non-irritating makeup removers and facial cleansers, avoid excessive rubbing, and protect the skin barrier[2].
- Keep skin moisturized: Moisturized skin is easier to remove dead skin cells and reduces friction damage[2].
- Choose the right product: Choose physical (scrub, microparticles) or chemical (acids, enzymes) exfoliating products according to skin type[3][6].
- Massage technique: Massage in gentle circular motions, avoiding excessive force[3].
- Rinse thoroughly: Wash with warm water to avoid residual irritants[2].
- Subsequent moisturizing and repairing: After exfoliation, the skin is more fragile and needs to be replenished with moisturizing and repairing ingredients immediately[2].
3. Frequency recommendations
It is generally recommended to use 1 to 3 times a week, depending on the skin type and the mildness of the product. Sensitive or dry skin should reduce the frequency to avoid irritation[3][4].
3. Cuticle protection: the key to protection and nourishment
1. Sunscreen is the cornerstone of cuticle protection
Ultraviolet rays are the main culprit for damaging the stratum corneum, which will accelerate skin aging and barrier damage. Continuous use of sunscreen products is an indispensable part of maintaining the health of the stratum corneum[1][2].
2. Replenishing natural moisturizing factor (NMF)
The moisture content of the stratum corneum determines the softness and elasticity of the skin. Ingredients such as amino acids, urea, and sodium lactate can effectively replenish the moisture of the stratum corneum and maintain its moisturizing function[1][5].
3. Avoid excessive cleansing and irritation
Excessive face washing, frequent exfoliation or the use of strong acid products will damage the sebum membrane and stratum corneum structure, causing skin sensitivity and dryness. Gentle cleansing and moderate maintenance are the correct attitude to protect the keratin[2][5].
4. Continuous and gentle maintenance habits
Regular and continuous use of skin care products suitable for your skin type, combined with gentle massage, can promote keratin metabolism and repair, allowing the skin to maintain a healthy state for a long time[2].

Maintaining the stratum corneum is the foundation of skin health. Exfoliation and keratin protection are not opposites, but complementary dual tasks. Only by mastering the appropriate removal of dead skin cells and gentle nourishment and protection at the same time can the skin show natural luster and elasticity. Strengthen the skin barrier from the base, focus on sun protection and hydration, and use the right products and the right way to build a solid and soft protective wall for the skin in daily care.
