To protect the skin, most people only know about sun protection, hydration or skin care products. In fact, there are many other issues that should be paid attention to.
First of all, we need to know what is hurting our skin. There are a few important points:
Free radical
AGEs advanced glycation end products
Loss of collagen
Inflammation
Wrinkle
1. Types of wrinkles
Wrinkles can be divided into 4 basic types according to the cause of their occurrence:
Intrinsic Wrinkles: Wrinkles that result from the natural aging of the skin
Actinic wrinkles: Wrinkles caused by sun exposure
Dynamic wrinkles: wrinkles caused by facial expressions
Gravitational wrinkles: Wrinkles caused by gravity
There are many reasons for wrinkles, such as sun exposure, heredity, estrogen deficiency, disordered work and rest, unhealthy diet, smoking and drinking, environmental pollution, etc., which can be divided into internal factors and external factors.
2. Wrinkle prevention
A. What we can do
Developing good living and eating habits will produce the greatest and longest-lasting effects.
Proper exercise and stretching can not only enhance physical fitness, but also delay the formation of wrinkles, especially dynamic wrinkles and gravity wrinkles.
Eat more foods with antioxidant (vitamin C, vitamin E, selenium, carotene, lycopene, coenzyme Q10), such as fried tomatoes (lycopene), blueberries, grapes, soybeans, green tea, etc.
B. What skin care products can do
Resistance to UV radiation (sun protection)
Protects the skin barrier (moisturizing)
Antioxidant (scavenging excess free radicals)
Promote cell proliferation and metabolism (exfoliation)
Antioxidant
1. Antioxidant representative ingredients: astaxanthin, fullerene, vitamin C, vitamin E, selenium and its compounds, coenzyme Q, lycopene.
2. The principle of anti-oxidation: remove excess free radicals, one of the functions of free radicals is to induce transcription factors (such as AP-1 and NF-κB) to increase the expression of matrix metalloproteinases (MMP), one of which is collagen Enzymes, it can make collagen gradually lose its original properties, and the skin loses its elasticity and wrinkles and sags.
3. Common antioxidants
▍Vitamin C
Vitamin C is the most common antioxidant ingredient, which has anti-oxidation, anti-wrinkle, whitening and certain anti-inflammatory effects. The human body depends on foreign food for vitamin C intake, but basically there is no problem of vitamin C deficiency. It is currently believed that oral vitamin C does not increase its content in skin cells, so if you want to work on the skin, you have to start with topical products.
▍Vitamin E
The most well-known fat-soluble antioxidant is vitamin E, but the way vitamin E exerts its greatest effect is to work synergistically with vitamin C to increase the antioxidant effect.
4. Others
Rebuild skin extracellular matrix
The extracellular matrix (ECM) of the dermis contains many protein matrix components: structural proteins (collagen, elastin) and adhesive proteins (fibronectin, laminin). The decline in the content and quality of ECM is also an important feature of skin aging, so rebuilding ECM is also a way. Oral collagen is useless, not as effective as collagen peptides, rhodiola, ginseng and other extracts, they can promote fibroblast division and promote their synthesis and secretion of collagen.
