The Core Role of Glutathione Powder is Inhibition of Tyrosinase
1. What is glutathione powder?
glutathione powderis composed of glutamic acid, cysteine, and
glycine. It contains a thiol-containing tripeptide, referred to as
GSH, which is the collective name of glutathione powderglutathione
powder+ thiol SH. With some whitening substances, such as
tranexamic acid, are mainly used for non-whitening in the early
clinical stage. Detoxification of glutathione's core role in the
clinic, so it has a significant role in purifying the internal
organs, such as repairing liver and kidney organs Damage, exclude
heavy metals in the body. It was later discovered that glutathione
powderhas the effect of whitening the skin and improving skin
2. Why is glutathione powder whitening?
Core role: Inhibition of tyrosinase synthesis:
Glutathione powder can purify the internal environment, remove free
radicals, and delay skin aging. So how does it achieve whitening
Since the amount of melanin synthesis is positively related to
tyrosinase activity, blocking tyrosinase has become the key to
preventing black. There are various components that can inhibit
tyrosinase activity, such as hydroquinone, kojic acid, arbutin,
azelaic acid, and tranexamic acid. The mechanism of action is
The cysteine in glutathione powder has such a function. It was
found in medical tests that cysteine can reduce the activity of
tyrosinase. Cysteine is an amino acid containing thiol group. The
thiol group has a strong nucleophilic effect. The thiol group can
quickly react with dopaquinone to quickly form a colorless dopa
derivative, thereby blocking the conversion of dopa to pigment.
So how is melanin in the skin synthesized? In fact, we are all
children of the sun. When the sun shines on our body, a series of
chain reactions are triggered. The tyrosine is converted into dopa
under the action of tyrosinase, which is the synthesis of melanin.
The first decisive step. Tyrosine is an amino acid necessary for
physiological activities and is abundantly and widely found in the
human body. The tyrosinase activity in darker-skinned skin is
approximately three times that of lighter-skinned skin. To control
skin blackening, you can find ways to block the effect of
3. Glutathione-Intervenes in the synthesis of melanin, the
mechanism mainly includes:
3.1 Direct inhibition of tyrosinase activity.
3.2 Free radicals can activate tyrosinase, while glutathione powder
can scavenge free radicals and inhibit tyrosinase activation.
3.3 Make the melanin synthesis pathway lean to melanin (instead of
melanin that darkens the skin)
