On the compatibility of glycolic acid, nicotinamide and arbutin
The compatibility of ingredients is the key to skin maintenance. Glycolic acid, nicotinamide and arbutin are all commonly used ingredients in skin care, but whether they can be used together needs to be carefully studied.

Glycolic acid belongs to the class of fruit acids and has excellent exfoliation effect. It can loosen the connection between keratinocytes, make the aging stratum corneum shed, accelerate skin metabolism, make the skin smooth and delicate, and can promote collagen production and enhance skin elasticity.

Niacinamide is also very popular in the field of skin care. It can effectively regulate the oil secretion of the skin and improve the appearance of enlarged pores; it can also prevent the transfer of melanin to epidermal cells, achieving the purpose of whitening and brightening the skin tone; at the same time, it has the power to repair the skin barrier and enhance the skin's ability to resist external stimuli.

Arbutin, a natural whitening ingredient, can inhibit the activity of tyrosinase, reduce the synthesis of melanin from the source, thereby fading pigmentation, brightening the skin tone, and making the skin fair and even.

As for whether these three can be used in combination. Glycolic acid can reduce the pH of the skin due to its acidic properties. Niacinamide is in an acidic environment. When the pH value is lower than 5.5, it may be converted to niacin. Niacin may cause redness, tingling and other discomforts to the skin. However, if properly prepared and the pH value of the product is controlled to maintain it within an appropriate range, glycolic acid and niacinamide are not absolutely impossible to use together.

Arbutin, on the other hand, has relatively stable chemical properties. Under normal circumstances, it has no obvious adverse reactions with glycolic acid and niacinamide. However, it should be noted that glycolic acid will thin the stratum corneum of the skin and enhance skin sensitivity. At this time, if the concentration of arbutin is too high, it may cause skin discomfort.

Therefore, if you want to use glycolic acid, nicotinamide and arbutin in combination, you should first check the product formula carefully, pay attention to its pH value and the concentration of each ingredient. Try the sample to observe the tolerance of the skin. If the skin is more sensitive, you need to be cautious, or consult a professional for advice first. In this way, you can use your strengths and avoid your weaknesses when taking care of your skin to achieve the ideal skin beauty effect.
