Summary of effective concentrations of common active ingredients (2)

Ectoin

Effective concentration: 0.1% Ectoin is an amino acid derivative and an extreme enzyme component. It can be used in cosmetics to provide good moisturizing, anti-inflammatory, antioxidant, repairing, and anti-aging effects. It is expensive and generally effective when added in an amount of 0.1% or more.
Active peptides

Effective concentration: Several tens of ppm of active peptides are excellent anti-aging ingredients that can be effectively added in small amounts. The dosage can be as low as one hundred thousand or one millionth (i.e. 10ppm-1ppm). For example, the effective concentration of acetylhexapeptide-8 is several tens of ppm, mainly used to reduce dynamic lines and facial expressions. The effective concentration of blue copper peptide is several tens of ppm, and its main function is to stimulate collagen regeneration.
Pionin

Effective concentration: 0.002% Pionin, also known as quaternium-73, is known as the “golden ingredient” in acne treatment. 0.002% is effective and has outstanding antibacterial and anti-inflammatory effects. Generally, the addition amount should not exceed 0.005%. In addition, at a concentration of 0.002%, it also has a good inhibitory effect on the activity of tyrosinase.
Resveratrol

Effective concentration: 1% Resveratrol is a polyphenolic compound with multiple biological activities. When its concentration exceeds 1%, it can clear or inhibit free radical generation, inhibit lipid peroxidation, regulate antioxidant enzyme activity, and achieve antioxidant and anti-aging effects.
Ferulic acid

Effective concentration: 0.08% Ferulic acid (F.A) is a derivative of cinnamic acid (cinnamic acid), a plant phenolic acid that can promote the absorption of vitamins, improve melanin, and avoid melanin deposition. When its concentration exceeds 0.08%, it can promote the production of collagen and have a revitalizing and anti-aging effect. The amount of ferulic acid added in cosmetics is generally between 0.1% and 1.0%.
salicylic acid

Effective concentration: 0.5% Salicylic acid is a fat soluble organic acid that naturally exists in holly and poplar trees. It is mainly used in cosmetics to kill bacteria, reduce inflammation, and help peel off dead skin cells. When its concentration reaches 0.5-2%, it can have a good exfoliating and anti-inflammatory effect.
Arbutin

Effective concentration: 0.05%. Common whitening ingredients can effectively inhibit the biological tyrosinase in the skin, block the formation of melanin, and fade pigmentation. When used, avoid light. 0.05% concentration of arbutin can significantly inhibit the accumulation of tyrosinase in the cortex, prevent pigmentation and freckles, and have a whitening effect on the skin.
Allantoin

Effective concentration: 0.02% Allantoin is an ingredient that can be used in both skincare and hair care products. Allantoin used in skincare products not only has moisturizing, repairing, and soothing effects, but also has anti-inflammatory and antioxidant effects; Used in hair care products to relieve itching and moisturize hair. When its concentration reaches 0.02%, it can promote cell tissue growth, metabolism, soften keratin layer proteins, and accelerate wound healing speed.
ceramide

Effective concentration: 0.1% ceramide is a natural moisturizing factor that exists in lipids (fats) in the skin. It has good moisturizing and repairing effects, can enhance the skin barrier, prevent water loss, and resist external stimuli. Generally, only about 0.1% to 0.5% can be effective.
caffeine

Effective concentration: 0.4% Caffeine has strong antioxidant properties and can help resist the damage of UV rays and free radicals to the skin. Many eye essence or eye creams also contain caffeine, which is also used to remove eye edema. When its concentration exceeds 0.4%, caffeine can promote the body’s metabolism, thereby accelerating the breakdown of fat.
