Green Tea On Your Skin!
Use green tea to relieve red skin! Green tea has amazing anti-oxidant, anti-aging, and anti-inflammatory properties. The super ingredient is called Epigallocatechin gallate (EGCG). It’s a catechin and an abundant polyphenol found in green tea that has cooling and hydrating effects on the skin. It can also relieve the redness and itchiness caused by acne, eczema, and psoriasis!
Melanin is synthesized by transformation of l-tyrosine and protects our skin from external stress. Excessive melanin production can cause age spots, freckles, and darkening of the skin. EGCG can help reduce that darkening effect and even lighten skin overtime so you see it in a lot of cosmetic products!
Aging Damages Your Skin
Skin aging occurs through two mechanisms—intrinsic and extrinsic aging. In intrinsic aging, decreased proliferative activities of skin cells lead to cellular senescence due to reduced synthesis of collagen and elastin. As we age, we lose the ability to produce collagen and elastin that support healthy skin. That’s why I recommend taking my collagen powder everyday to maintain healthy and hydrated skin!
The Sun Damages Your Skin
Extrinsic aging is caused by stimuli from the external environment such as ultraviolet (UV) irradiation, air pollution, and fine dust. Skin aging induces dehydration of skin cells. The key molecule involved in skin hydration is hyaluronic acid (HA). HA has been reported to increase skin moisture by regulating the hyaluronic acid synthase (HAS) genes, and several studies have confirmed that retinoic acid (vitamin A) can effectively regulate HA in epidermis. In the wound healing process, epidermal HA has been reported to promote cell proliferation and differentiation. Hyaluronidases (HYAL) is an enzyme that intracellularly degrades hyaluronic acid (HA). TLDR: Hyaluronic acid (HA) – GOOD. Hyaluronidases (HYAL) – BAD.
UVB rays can cause inflammation in the cell nucleus which can make skin conditions like acne, eczema, and psoriasis worse. Some people say that sun exposure helped improve their skin. Most likely, they are vitamin D deficient so stepping outside helped them get more vitamin D which has powerful anti-inflammatory properties. The UVB rays can be a blessing and a curse! At the end of the day, you have to understand your body’s weaknesses and limitations. The sun can help or hurt your skin depending on your skin sensitivity. I found out that the sun was hurting my skin when I tried to get vitamin D! I now take vitamin D supplements to meet my daily requirement.
EGCG Protects The Skin From Sun Damage
TLDR: EGCG – GOOD. Hyaluronic acid (HA) – GOOD. Hyaluronidases (HYAL) – BAD.
EGCG increased the hydration of the skin barrier and protected HA in the epidermis. EGCG reduced the bad effects of HYAL on the skin. So the next time your have a bad sunburn or a severe case of acne/eczema/psoriasis, try putting tea bags on your skin to relieve red skin and reduce all that inflammation!
