L-glutathione:common skin whitening ingredients

where is it L-glutathione from?

It is a tripeptide compound composed of glutamic acid, cysteine and glycine. It has a variety of important physiological functions in the human body, such as antioxidant, detoxification, and immunity enhancement.

Regarding the extraction source of L-glutathione, it can be mainly obtained from the following aspects:

  1. Chemical synt hesis: L-glutathione can be synthesized by chemical methods, which is a common production method.
  2. Fermentation: fermentation using microorganisms is also a way to produce L-glutathione. Under specific conditions, microorganisms can synthesize and secrete L-glutathione.
  3. Natural extraction: L-glutathione is also found in certain foods, such as yeast and animal liver. However, these natural sources contain relatively low levels of L-glutathione and are not suitable as raw materials for large-scale production.



What are the effects of L-glutathione topically on the skin?

01 L-Glutathione has significant antioxidant properties. It fights free radicals and reduces damage to the skin from the external environment, thus helping to slow down skin aging. This antioxidant property makes L-glutathione play an important role in protecting the skin from UV damage and reducing the signs of skin aging.

02 L-glutathione also has a whitening effect. It can inhibit the formation of melanin and reduce skin pigmentation, resulting in a more even and fairer complexion. This property makes L-glutathione have significant effect in improving dull skin and lightening pigmentation.

03 L-Glutathione can improve the skin’s moisture retention ability, increase the skin’s elasticity, and make the skin smoother and more delicate. At the same time, it can also reduce skin inflammation, relieve skin sensitivity, redness and swelling, and help the skin restore its healthy state.

What is its whitening mechanism? (Principle)

The whitening mechanism of L-Glutathione is mainly based on its antioxidant and melanin-forming inhibiting effects. Specifically, the following is a detailed explanation of the whitening principle of L-glutathione:

First of all, L-glutathione, as an antioxidant, can scavenge free radicals in the body. Free radicals are an important factor in skin aging and hyperpigmentation, they damage the structure and function of skin cells, leading to loss of elasticity, wrinkles and discoloration.L-Glutathione reduces oxidative stress by neutralizing free radicals, thus protecting skin cells from damage and maintaining the skin’s healthy and youthful state.

Secondly, L-Glutathione can inhibit the formation of melanin. Melanin is the determining factor of skin color, when melanin is overproduced or unevenly distributed, it will lead to skin discoloration and dullness. l-Glutathione can achieve whitening effect by interfering with the biochemical process of melanin production and reducing the activity and number of melanocytes.

In addition, L-Glutathione can also promote the metabolism of skin cells and accelerate the shedding of the aging stratum corneum, resulting in smoother and more delicate skin. At the same time, it can also enhance the skin’s moisturizing ability, improve the dryness and roughness of the skin, and make the skin more hydrated and glowing.

Can it be used for a long time?

YES, L-Glutathione can be used for a long period of time, but only if it is used in the right way and at the right dose, and if it does not produce any adverse reactions.
