The patch mask carries liquid and is occlusive, it allows the stratum corneum to absorb a large amount of water quickly, so that it is plumped and swollen, arranged neatly, and the surface is smoother, so it reflects light evenly and the skin appears visually whiter. However, this moisture does not enter the deeper layers of the skin, and it will evaporate quickly in a short period of time, and the skin will return to its original state. Therefore, the immediate effect of the mask is not long-lasting, and it is difficult to say that it will improve the skin texture. In addition, when the stratum corneum absorbs water and swells, the structure begins to loosen, and when this protective brick wall is no longer hard, it is easier for the external imps to penetrate and irritate the skin. Applying a mask frequently or for long periods of time is tantamount to "self-destructing", which can damage the stratum corneum, which is the skin barrier, leading to sensitivity, dryness, and even inflammation. Therefore, face masks are only suitable as temporary skin beautifying products and are not essential for skin care.
 
Since the mask plays the role of "icing on the cake", "less but better" is the essence. Due to the simple process of making facial masks, there are a large number of inferior products circulating in the market. When the stratum corneum is weakened, the bacteria and risk ingredients in inferior products can not take advantage of the opportunity to enter and damage the skin. In addition to being hygienic and safe, high-quality masks generally add moisturizers and other ingredients to prolong the skin beautification effect. In addition, the temperature increase caused by the sealing of the mask cloth and the loosening of the stratum corneum make it easier for skin care ingredients to penetrate, so some products also have instant brightening and soothing effects. La Mer's mask continues to be used in the event of redness, breakouts or excessive dryness, soothing and calming enough to take on an "emergency" role, in line with the immediacy of the mask itself.
 
The Repair Essence Mask is claimed to be infused with the original liquid of the star product Repair Essence, and the two are indeed similar in composition, and also follow the core ingredients and repair properties of La Mer. The Essence Mask is enriched with Miracle Broth Seaweed Extract, a unique moisturizing ingredient of La Mer, supplemented with moisturizers such as butylene glycol, sodium hyaluronate, and urea. In addition, it is formulated with anti-inflammatory and antibacterial agents such as sunflower seed cake, sesame seed powder and eucalyptus globulus leaf oil to repair and soothe main effect. At the same time, hook salai and lithomorphic flower rai extracts are unique ingredients to the essence mask, which have similar effects to seaweed extracts and enhance the moisturizing effect. The repair essence mask cloth is made of pure cotton material, which is soft and skin-friendly, but slightly thicker, but fortunately, the cut is reasonable, the fit is quite high, and it is not stuffy. The essence mask is a repairing type, more aimed at problem skin, and the price of a single piece is 230 yuan, which is recommended for users to use as an instant skin care product when there are adverse conditions such as sudden mouth closure, allergies, redness, etc.
 
It should be reminded that even if it is a calming and soothing mask, the acne skin needs to shorten the time and frequency of applying the mask to less than 10 minutes and less than once a week, because long-term stuffy application may lead to acute blockage of the hair follicle opening and increase the possibility of acne. The same is true for allergic skin, where a damaged skin barrier increases the likelihood of allergies.
 
The Moisturizing Repair Mask is a derivative product of another star product, the Moisturizing Cream, which inherits the gentle and mature formula of the cream. Seaweed ferment is the main ingredient, with lecithin, squalane and other moisturizing and emollient agents, supplemented by a variety of plant extracts, to have a moisturizing and anti-inflammatory effect. The moisturizing mask is made of pure cotton mask cloth, which has a thick texture and carries a moderate amount of essence, and almost no excess liquid remains in the bag. The mask is divided into two masks, the upper and lower masks, which fit the face well and are soft to the touch, so it is best to lie flat when applying. The moisturizing and repairing mask has both moisturizing effect and calming and stabilizing effect, but at the price of 430 yuan/piece, it is not cost-effective as a moisturizing product alone, and it is more recommended to use it in the case of unstable skin conditions for facial allergies or very dry skin.
