Summary of effective concentrations of common active ingredients (1)

Although the relationship between ingredient concentration and cosmetic efficacy is not a simple linear relationship, ingredients can only emit light and heat when they reach the effective concentration.
Based on this, we have compiled the effective concentrations of common active ingredients, and now we will take you to understand them.

hyaluronic acid
Effective concentration: 0.02% Hyaluronic acid (HA) is also a component of the human body and has a special moisturizing effect. It is currently the most moisturizing substance in nature and is known as the ideal natural moisturizing factor. The general addition amount is around 0.02% to 0.05%, which has a moisturizing effect. If it is hyaluronic acid solution, it will be added to more than 0.2%, which is quite expensive and effective.

Retinol
Effective concentration: 0.1% is a classic anti-aging ingredient, and its efficacy is also guaranteed. It can accelerate collagen production, thicken the epidermis, and accelerate the metabolism of epidermis. Because A alcohol can be easily absorbed by the skin, it has been clinically proved that the addition of 0.08% is enough to make vitamin A play a anti-aging effect.

nicotinamide
Effective concentration: 2% niacinamide has good penetration, and a concentration of 2% -5% can improve pigmentation. 3% niacinamide can better resist the damage caused by blue light exposure to the skin, and 5% niacinamide has a stronger effect on brightening the skin tone.

astaxanthin
Effective concentration: 0.03% Astaxanthin is a broken chain antioxidant with strong antioxidant capacity, which can remove nitrogen dioxide, sulfides, disulfides, etc. It can also reduce lipid peroxidation and effectively inhibit lipid peroxidation caused by free radicals. Generally speaking, an addition amount of 0.03% or more is effective.

Pro-Xylane
Effective concentration: One of the leading active ingredients of 2% Europa, it is named Hydroxypropyl Tetrahydropyranthriol in the ingredient list. It is a glycoprotein mixture that can stimulate the production of skin aminoglycans at a dosage of 2%, promote the production of collagen type VII and IV, and achieve the effect of firming the skin.

377
Effective concentration: 0.1% 377 is the common name for phenethyl resorcinol, which is a star ingredient known for its whitening effect. Generally, 0.1% to 0.3% can take effect, and excessive concentration can also lead to adverse reactions such as pain, redness, and swelling. The typical dosage is usually between 0.2% to 0.5%.

vitamin C
Effective concentration: 5% vitamin C can inhibit the activity of tyrosinase, protect the skin from UV damage, improve dullness, accelerate skin metabolism, and promote the production of collagen. 5% vitamin C can have a good effect. The higher the concentration of vitamin C, the more stimulating it is. After reaching 20%, even increasing the concentration will not improve the effect.

vitamin E
Effective concentration: 0.1% Vitamin E is a fat soluble vitamin, and its hydrolyzed product is tocopherol, which is one of the most important antioxidants. It can brighten skin tone, delay aging, reduce fine lines, and make the skin more elastic. Vitamin E with concentrations ranging from 0.1% to 1% can have antioxidant effects.
