On the suitability of glycolic acid toner and niacinamide
husband's skin care approach, ingredient suitability is the key. Glycolic acid toner is lively and often rejuvenates the skin; niacinamide is also beneficial to the skin. Whether the two are suitable or not is subject to different opinions. It should be analyzed in detail today.

Glycolic acid, a family of fruit acids, has the effect of dissolving keratin, which can loosen the connection between keratinocytes, promote the renewal of the stratum corneum, and make the skin smooth and delicate. However, its acidic characteristics may cause temporary discomfort to the skin, especially sensitive skin.

Niacinamide can block the transport of melanin, brighten and whiten the skin, and strengthen the skin barrier and regulate oil secretion. It is relatively mild in nature and is mostly favored by skin care products.

If the two are used together, theoretically, glycolic acid can reduce the pH value of the skin, or affect the stability of nicotinamide, causing it to be converted into niacin. Niacin is irritating, or causes skin redness and itching. But in practical application, many factors affect the adaptation result.

First, the concentration is important. If the concentration of glycolic acid and nicotinamide is low, the reaction between the two may not be significant, and the skin may be tolerated. Second, product formula. Good formula can use buffers and other means to maintain an appropriate pH value and ensure the stability of nicotinamide. Third, individual differences. Skin sensitivity and tolerance are different, and your mileage may vary.

Therefore, if you want to use glycolic acid toner and niacinamide, you should try it locally to observe the skin's reaction. When using it for the first time, you can use it at intervals, and wait for the skin to adapt, and then gradually increase the frequency. In this way, you can seek advantages and avoid disadvantages and achieve the best of skin care.
