Girls can make themselves more beautiful as long as they find the whitening method that suits them. Whitening skin care products are now on the market. There are many on the Internet. Which ingredients for skin whitening are safe and reliable? Some girls don’t know much about it, so I will introduce it below.

1. Safe whitening ingredient

L-vitamin C

Vitamin C, whose scientific name is ascorbic acid, is a strong reducing agent and has antioxidant effects. Since vitamin C is an optically active molecule, it is divided into left-handed and right-handed according to its optical rotation. L-VC is the only form of VC that can be directly absorbed by human skin. It has the functions of promoting collagen proliferation, repairing skin damage caused by ultraviolet rays, and diluting melanin. Due to the light-proof nature of VC, such products must be used at night, otherwise they will only achieve half the result with twice the result.

Nicotinamide

Nicotinamide is vitamin B3. Due to its anti-glycation effect, it can reduce and prevent skin problems such as dull skin color and yellowing caused by early aging. It can also repair the damaged stratum corneum lipid barrier, improve skin resistance, and reduce sebum content. The production of fatty acids and triglycerides, thereby tightening pores and reducing the severity of acne breakouts.

Kojic acid

Kojic acid is extracted from the fermentation broth of Aspergillus and Penicillium. It has the ability to inhibit tyrosine_(tyrosine in tyrosinase Under the catalytic action, it undergoes complex oxidation and polymerization with oxygen free radicals, and finally synthesizes melanin), thereby reducing and inhibiting the production of melanin and diluting spots. Among the existing whitening ingredients, it has the most obvious effect, but because it is very easy to oxidize, use it as soon as possible after opening.

A fruit acid

A fruit acid is an organic acid extracted from fruits. Among them, glycolic acid extracted from sugar cane is the most effective. It is used to remove excessive keratinization. After stratum corneum, it stimulates the growth of new cells, while helping to remove fine lines on the face, dilute epidermal pigment, and make the skin softer, whiter, smoother and more elastic. However, it is easy to cause sensitization and cause the stratum corneum of the skin to become thinner.

Plant extracts

The safest and mildest whitening ingredients, which are usually used in a variety of combinations. Long-term use will have no side effects on the skin. It works by inhibiting the activity of tyrosinase, and some plant extracts also have anti-allergic and anti-inflammatory effects.

Arbutin: After penetrating into the skin, it can effectively inhibit the activity of tyrosinase, achieve the purpose of blocking the formation of melanin, reduce the accumulation of melanin, prevent freckles, chloasma and other pigmentation, and make the skin produce unique Whitening effect.

Licorice extract: Extracted from the root of licorice. The oil-soluble part of licorice extract can inhibit enzyme activity. The water-soluble glycyrrhizinate has a mild anti-inflammatory effect and is generally added in the sun. Aftercare product, used to eliminate subtle inflammation on the skin after intense sun exposure.

Purple grass extract and mantle grass extract: can effectively inhibit the formation of melanin granules, slow down the melanin production process, and effectively slow down the transmission of melanin granules to epidermal cells.

How to use: It is recommended to drink it by soaking it in water and adding a small amount of rock sugar.

Lemon is definitely a fruit for anti-spot beauty. This is because lemon contains citric acid, which can effectively prevent skin pigmentation.

However, lemons are extremely sour, so it is recommended to soak them in water, add a small amount of rock sugar, and drink them in the form of lemon juice. Its function is to whiten the skin, prevent the aging of skin blood vessels, and eliminate facial pigment spots.
