What are the whitening effects of niacinamide, vitamin C, astaxanthin, and tranexamic acid
Whitening is a beauty goal pursued by modern people, and commonly used whitening ingredients include niacinamide, vitamin C, astaxanthin, and tranexamic acid. These components exert whitening effects through different pathways. This article will explore their mechanisms of action and their differences from a molecular level perspective.
1、 Nicotinamide
Niacinamide, also known as vitamin B3, is a water-soluble vitamin. Niacinamide has multiple effects on the skin, with the most important being whitening. The mechanism of action of niacinamide mainly includes the following two points: inhibiting melanin synthesis. Melanin is a pigment particle in the skin, and niacinamide can achieve whitening effects by inhibiting the formation of melanin. Research has found that niacinamide can inhibit the activity of melanin synthase, thereby reducing melanin synthesis. Nicotinamide can promote skin metabolism, accelerate the metabolism of the stratum corneum, and make it easier for the skin to absorb other whitening ingredients. In addition, niacinamide can also improve the skin's barrier function, increase the skin's ability to retain moisture, and make the skin more tender.
2、 Vitamin C
Vitamin C, also known as vitamin C, is a water-soluble vitamin. The mechanism of action of vitamin C in whitening mainly includes the following points: inhibiting melanin synthesis Vitamin C can inhibit the activity of tyrosinase, thereby inhibiting melanin synthesis. In addition, vitamin C can restore melanin, reduce its content, and make the skin fairer. Antioxidant vitamin C has strong antioxidant ability, which can neutralize free radicals and inhibit the formation of melanin. In addition, vitamin C can promote the synthesis of collagen, enhance skin elasticity, and make the skin younger.
3、 Astaxanthin
Astaxanthin is a natural pigment mainly found in seafood such as shrimp, crab, and lobster. The mechanism of action of astaxanthin in whitening mainly includes the following points: inhibiting melanin synthesis astaxanthin can inhibit the activity of melanin synthase, thereby reducing melanin synthesis. In addition, astaxanthin can regulate the distribution of melanin, making the skin more even. Antioxidant astaxanthin has strong antioxidant ability, which can neutralize free radicals, reduce oxidative damage, and thus reduce the formation of melanin. Astaxanthin can also inhibit the activity of tyrosinase, thereby reducing the synthesis of melanin.
4、 Chuanming acid
Chuanming acid is an alpha hydroxy acid commonly used for skin whitening. The mechanism of action of tranexamic acid in whitening mainly includes the following points: inhibiting melanin synthesis. tranexamic acid can inhibit the activity of melanin synthase, thereby reducing melanin synthesis. In addition, hyaluronic acid can also promote the metabolism of melanin, making the skin brighter. Promoting the metabolism of hyaluronic acid in the stratum corneum can promote its metabolism, increase the skin's absorption capacity, and make it easier for other whitening ingredients to penetrate deep into the skin, achieving better results. Antioxidant hyaluronic acid has a certain antioxidant capacity, which can neutralize free radicals, reduce oxidative damage, and make the skin healthier.
Overall, these whitening ingredients have slightly different mechanisms of action, but they can all reduce the formation of melanin through different pathways, improve skin tone, and make the skin brighter. In addition, they can also have some other effects on the skin, making it healthier and more beautiful. Therefore, when choosing whitening products, one can choose appropriate ingredients based on their skin type and needs to achieve better whitening effects.
