Vitiligo patients should never use skincare products containing these ingredients!

Vitiligo patients have many questions when using skincare products: what ingredients are not suitable? Do you have any precautions? How to choose skincare products that are suitable for oneself? For ordinary skin, melanin is the main factor affecting skin color, while for vitiligo patients, melanin is the main factor assisting vitiligo. Therefore, many products on the market containing melanin inhibiting ingredients are not suitable for vitiligo patients.

1. Skincare products containing ingredients that inhibit melanin production

√Principle: There is an inseparable relationship between the production of melanin and tyrosinase, and inhibiting the activity of tyrosinase can effectively suppress the production of melanin.

Common ingredients: arbutin, tranexamic acid, phenethyl resorcinol, hydroquinone, quercetin.

√ Analysis: Phenol can block the conversion process of tyrosinase and control the biosynthesis of melanin; Kojic acid can inhibit the production of free tyrosinase, achieving the purpose of inhibiting melanin formation. In addition, arbutin, tranexamic acid, phenethyl resorcinol, and other compounds also have this effect.

2. Niacinamide containing skincare products:

√ Principle: After the formation of melanin, it is metabolized by cells and transmitted to the stratum corneum, resulting in a dull complexion of the skin. This inhibits the transmission of melanin to keratinocytes, ultimately achieving a whitening effect on the skin.

√ Common ingredients: Niacinamide

√ Analysis: For other populations, niacinamide has whitening, anti-aging, moisturizing, oil controlling, and acne reducing effects. But for vitiligo patients, niacinamide can inhibit melanin production, thereby affecting the recovery of vitiligo. Therefore, Xiaohua suggests that vitiligo patients should avoid using skincare products containing niacinamide.

3. Acidic acids such as fruit acid, phytic acid, and salicylic acid, as well as exfoliating skincare products;

√ Principle: When melanin reaches the stratum corneum, the most direct way to whiten is through exfoliation to remove melanin. Common acidic components such as fruit acid, phytic acid, and salicylic acid can accelerate the metabolism and peeling of melanin in keratin.

√Common ingredients: acid components such as fruit acid, phytic acid, salicylic acid, etc.

√ Analysis: These acidic ingredients peel off dead cells and melanin in the stratum corneum, making the skin appear more transparent. However, for vitiligo patients, these ingredients are extremely irritating and can easily damage the skin barrier if used improperly. Therefore, Xiaohua is not recommended for use.

4. Vitamin C containing skincare products can restore some keratin melanin:

√Principle: In addition to the already exfoliated melanin in the stratum corneum, VC and its derivatives can also reduce oxidative melanin to colorless reduced melanin, inhibit tyrosinase activity, and achieve whitening effects.

√ Analysis: For people who want to beautify their skin, it has antioxidant, purifying, enhancing skin elasticity, reducing wrinkles and other effects. Due to the catalytic role of tyrosinase in melanin synthesis, vitamin C skincare products can inhibit the activity of tyrosinase. Therefore, vitamin C containing skincare products also need to reduce the dosage for vitiligo patients.
