5 intensive skin care ingredients you need to know
Hyaluronic acid (HA) is a natural substance in the human body that functions to regenerate cells, lubricate the connective tissues and maintain moisture and elasticity of the skin.
Being applied on the skin, hyaluronic acid creates a protective barrier for the skin, making the skin soft and smooth. HA molecules have the ability to sink up to 1000 times the mass of water. So, HA is present in a myriad of skin care products today.
Being injected into the skin, HA has the effect of stretching the skin, eliminating wrinkles caused by aging. Since this is a natural ingredient available in the body, HA is much safer than synthetic chemicals. However, because HA molecules are so large that they cannot penetrate the epidermis, skin care products containing HA are not capable of stretching the skin.
Retinol is an active form of vitamin A, which is capable of exfoliating the skin, boosting the skin's production for new, healthier cells. Retinol also promotes the production of hyaluronic acid and natural collagen on the skin, making the skin healthy and stretched.
Using retinol will help you to strengthen the skin, reduce the damage from the sun and the environment, support acne treatment, reduce blotches, dark circles, wrinkles on the skin. This is considered to be the miracle of modern skin care technology.
Peptides are proteins that function to guide other cells to function. On the skin, peptides stimulate the development of elastin, help to improve skin elasticity or heal the wound. Peptides in the anti-aging products penetrate into the skin cells and regulate the cells that produce collagen, reduce redness on the skin and help the muscles relax, thereby reducing wrinkles.
A common anti-aging peptide is "palmitoyl pentapeptide". Many other peptides do not directly affect the skin but because their molecules are too small, they have the function of transporting other components to the dermal layer of the skin. Copper peptides, for example, carry copper molecules deep down the skin and improve its healing power.
If you pay attention to skin care, you must be familiar with AHA / BHA. Alpha hydroxy acids and beta hydroxy acids are organic acids that have the function of exfoliating. AHA is extracted from fruit and milk, including glycolic acid (from sugarcane), lactic acid (from milk), and malic acid (from apples and pears)... BHA is used to refer to salicylic acid (from plants) in the beauty industry.
Although both AHA and BHA are used for exfoliating, AHA (water-soluble) acts on the skin surface while BHA (oil-soluble) can penetrate deeper and help remove dirt and dead skin throughout the pores. BHA is mainly used for oily skin or acne prone skin that has problems with blackheads. AHA is used to lighten dry or dull skin.
However, you will often find products including both AHA and BHA with the ability to exfoliate thoroughly. The level of exfoliation depends on the intensity of the acid, so make sure you scrutinize and test it thoroughly before exfoliation with AHA / BHA.
Ceramide is a waxy lipid family that connects the cells that make up the stratum corneum. That means ceramides are long strands of lipids on the skin. Therefore, ceramides are essential to maintain and strengthen the skin's natural barrier. This barrier protects the skin from potential damage and toxins while keeping it hydrated.
Currently, there are 9 types of ceramide. If the amount of ceramide on the skin is too low or if the barrier to protect the skin is damaged, the skin will be dried, pimples and wrinkles will appear. Age, low humidity, sunlight, pollution... can reduce the amount of ceramide on your skin.
