(1) Precautions for sensitive skin and problem skin
For sensitive or fragile skin, it is necessary to focus on the mildness and safety of the product. It is recommended to use a milder facial cleanser.
(2) Foam has nothing to do with the effect of facial cleansers
The amount and fineness of the foam of facial cleansers have no direct relationship with the quality of facial cleansers. However, rich and fine foam is the key factor for many consumers to choose to use it repeatedly.
(3) Do not over-cleanse
Even if the lipids from the sebaceous glands are temporarily removed after cleaning, they will recover within a certain period of time. However, the lipids from the stratum corneum need time to recover, and the moisture of the skin is mainly maintained by the NMF (natural moisturizing factor) contained in the skin. Therefore, do not over-cleanse the skin to avoid excessive removal of the cortical membrane and the dissolution of NMF and intercellular lipids (ceramide, cholesterol).
(4) Facial cleansers that claim to be effective
Since facial cleansers stay on the face for a very short time, generally only a few minutes, and are rinsed off at the end, in fact, some active ingredients are difficult to remain on the face. Therefore, it is relatively difficult to achieve the so-called whitening, freckle removal, anti-wrinkle and other effects by relying on facial cleansers.
