What are the ingredients in marijuana that are worth studying with such great fanfare?
Cannabis is a very controversial plant. In fact, hundreds of active components have been isolated. The two most important components, CBD cannabinol and thc tetrahydrocannabinol, can be said to be angels and demons. The molecular structures of the two substances are similar and have been regarded as the same substance for a long time, but modern medicine has found that, The two monomer components are quite different in efficacy.
The reason why marijuana has become a controversial plant, which has a spiritual effect, that is, hallucinogenic, and addictive is this tetrahydrocannabinol (THC, hereinafter referred to as THC).
On the contrary to hallucinogenic THC, CBD (cannabidiol, hereinafter referred to as CBD) CBD is a cannabinoid with no mental activity, no hallucinogenic addiction and no toxic and side effects. It is a substance similar to the function of endogenous cannabinoid. It is scientifically proved that CBD can enhance the activity of CB1 receptor, regulate a variety of physiological and psychological processes, and help to treat a variety of diseases.
CBD not only has no psychotoxicity, but also blocks the influence of central nervous system caused by thc to a certain extent. In other words, CBD can even resist the addictive effect of THC.
Different varieties of marijuana contain very different contents of two components, which is what we call "industrial marijuana" and "entertainment marijuana", which can be considered as plants with different properties.
Internationally, marijuana with THC > 0.5% is entertainment marijuana, also known as drug marijuana, which can be used to extract drugs and is prohibited from cultivation in most countries; 0.3% < thc < 0.5% is intermediate marijuana, which is also banned because of some addiction; THC < 0.3% is industrial marijuana, which does not show spiritual activity. It is widely used in textile, papermaking, medicine, daily chemical and other fields.
CBD used in drugs and cosmetics generally comes from industrial marijuana. Its THC content is very low. It is a kind of marijuana allowed to grow. In addition, hemp seed oil extracted from industrial hemp is rich in linolenic acid and linolenic acid, which has good antioxidant and moisturizing effect, so it can also be used for skin care.
Of course, after CBD and thc are clearly distinguished, many students will ask, what benefits can CBD bring to our skin? Let's sort out the specific mechanism of CBD in skin care.
CBD in industrial marijuana has been proved to have anti-inflammatory and antioxidant activity, regulate cell cycle and immune cell function, inhibit the production of a variety of pro-inflammatory cytokines, inhibit immune cell proliferation, activation, maturation, migration and antigen presentation, and can be used to improve the skin.
Skin care efficacy of CBD
CBD can inhibit sebum secretion, anti proliferation and anti-inflammatory effects of sebaceous gland cells.
02. Anti sensitivity
CBD may help to improve allergic contact dermatitis (ACD).
03. Some skin diseases such as psoriasis
CBD can inhibit the excessive proliferation of human keratinocytes, suggesting that it may be beneficial to psoriasis.
04. Anti skin redness
CBD can effectively inhibit the proliferation of human umbilical vein endothelial cells, inhibit endothelial cell migration, invasion and germination in vitro, and inhibit angiogenesis in vivo.
05. Fighting vitiligo
CBD can increase tyrosinase activity and melanin content in human melanocytes in a concentration dependent manner. It is inferred that CBD may have the potential to improve hypopigmented skin diseases.
In short, CBD has the following effects on the skin:
Repair: hemp leaf extract can effectively heal skin wounds, stimulate the growth of immune system and fibroblasts, and promote wound healing.
Anti acne: acne is an inflammatory reaction of the skin. Relevant studies have shown that CBD can activate the ECS system mentioned above and inhibit the proliferation and fat production of sebum cells, so as to control oil secretion, fight inflammatory reaction and eliminate acne 。
Antioxidation & anti-aging: as a powerful antioxidant for neuroprotection, CBD is more powerful than vitamin C and vitamin E in antioxidation, slowing down aging and improving skin condition.
