Whitening ingredients and efficacy

Classification of whitening ingredients

From a functional point of view, various whitening ingredients can be divided into four categories:

1. Inhibiting melanin: that is, blocking whitening.

The same is the common whitening ingredients, such as kojic acid, arbutin, etc., they can inhibit the generation of melanin, with a strong light spot effect.

Disadvantages: It often needs to penetrate into the bottom of the skin to play its blocking role, which puts higher requirements on the product preparation.

2. Blocking melanin: that is, inhibiting melanin transport from melanocytes to keratinocytes, such as vitamin B3.

3. Fade melanin: that is, reduce whitening.

Blackening of the skin to produce spots is itself a process of skin oxidation. The vitamin C and its derivatives that we are familiar with are strong antioxidant small guards, which can restore the oxidized process, inhibit the oxidation reaction of melanin, and gradually whiten the skin.

Disadvantages: It is not a stable guard, it is easy to decompose in the air and lose efficacy.

4. Metabolic melanin: metabolic whitening.

Like fruit acid, salicylic acid A alcohol, etc., like peeling the egg shell, peeling the excessive cuticle of the skin, thereby taking the melanin away from the skin and making the skin new.

Disadvantages: This whitening method only removes the melanin on the surface of the skin, and melanin is present in the bottom of the skin, and constantly produces outwardly, so this method treats the symptoms rather than the root cause, but also needs to be used in combination with deep whitening products, and sensitive skin should be careful to use this exfoliating whitening method, combined with moisturizing and sunscreen.
