Do you know when to anti-aging? 20 years old? 25, 30? Still 35? Pores are getting bigger and bigger, skin elasticity and delicacy are weakened, acne marks are getting harder and harder to eliminate, and aging distress signals such as wrinkles and fine lines appear. Are you ready for anti-aging?
But skin aging is more than that. If you want to do a good job of anti-aging, you must understand the mechanism of the skin, the factors of aging, and how to resist aging. As we all know, the skin is divided into three layers: epidermis, dermis, and subcutaneous tissue:
Epidermis: From the outside to the inside are the stratum corneum, the granular layer, the spinous layer, and the basal layer.
Dermis layer: divided into papillary layer and reticular layer, composed of fibers, matrix, and cells, so most skin appendages are in the dermis layer, such as sweat glands, nerves, hair follicles, blood vessels, cells, etc.
Subcutaneous tissue: It is some connective tissue such as adipose tissue and muscle tissue.
However, the epidermis and dermis, which are closely related to human skin aging, change when our skin sends out the distress signal of aging:
one. Changes in skin structure:
1. Epidermis: The function of the stratum corneum declines, causing hypertrophy of the stratum corneum, and loss of proliferation vitality of epidermal cells;
2. Dermis: The number and function of fibroblasts are reduced, the activity of elastin and collagen is reduced and the loss is accelerated. The appearance of the skin is roughness, loss of elasticity, wrinkles, enlarged pores, and pigmentation.
3. Basement membrane DEJ damage: The epidermis and dermis are demarcated by the basement membrane, composed of type IV collagen, laminin, proteoglycan, etc. Its function is to maintain the mechanical strength of the skin, which will be damaged by long-term solar radiation, environmental pollution, and natural aging. basement membrane. The performance of the skin is loss of elasticity and wrinkles.
Two factors affecting skin aging:
1. External factors: long-term sunlight exposure, and environmental pollution.
2. Intrinsic factors: In simple terms, the changes in the function of somatic cells with age.
How to do skin anti-aging?
1. Exogenous anti-aging:
① Prevention of UV rays
Choose suitable sunscreen products, preferably functional sunscreen products. For example, adding VC, bisabolol, edelweiss extract, etc., can relieve skin damage caused by long-term sun exposure. Sun protection clothing, sun hats, sun protection ice sleeves, sun protection masks, etc. have become essential for travel. Applying and wearing double sunscreen, "soft and hard" has become a new trend of sunscreen in recent years.
②Promote keratin metabolism
Mainly achieved by brushing acid, fruit acids (glycolic acid, mandelic acid, lactobionic acid, citric acid, etc.) and salicylic acid can promote the shedding of keratinocytes and effectively improve the dullness and acne caused by photoaging.
③Repair the barrier
Ceramide (one of the substances composed of skin, exogenous supplementation of ceramide can improve the skin barrier), natural moisturizing factor NMF (existing in keratinocytes, is a moisturizing ingredient secreted by the skin) to maintain moisture and maintain skin metabolism; Squalane (the sebum film component has good compatibility with the skin and can effectively repair the barrier), etc., as well as plant extracts such as Centella Asiatica extract, purslane extract, licorice extract, etc., which can inhibit inflammatory factors and promote immunity The role of regulation plays an important role in repairing the skin barrier.
Do a good job of daily care
The main ways of anti-aging skin care products can be divided into endogenous and exogenous:
1. Endogenous anti-aging:
①Supplementing collagen and elastin/anti-glycation
For example, retinol and its derivatives (enhance the vitality of basal cells, promote the secretion of glycosaminoglycans (GAG), and promote the synthesis of type I collagen), palmitoyl tripeptide-5 (increase elastin, hyaluronic acid, Production of glycosaminoglycans and fibronectin), humanoid collagen (replenishes lost collagen and moisture from the skin), palmitoyl pentapeptide-4 (stimulates collagen regeneration), baseline (regulates basement membrane expression properties), to promote the synthesis of glycosaminoglycans and proteoglycans), blue copper peptides (can promote collagen and elastin production).
②Reduce fine lines and wrinkles
For example, snake venom peptide can effectively block nerve transmission of muscle contraction information, relax facial muscles, and achieve the purpose of smoothing and wrinkling; Relax), Acetyl Hexapeptide-8 (the famous "Botox-like", which blocks the release of neurotransmitters and achieves a Botox-like wrinkle-removing effect).
3. Good living habits
Don't stay up late, and play less mobile phone. Regular work and rest will make the metabolism reach an excellent state. Electronic products radiate blue light and accelerate skin aging. At 24, take good care of your skin to prevent aging.
