Discussion on the Compatibility of Salicylic Acid, Niacinamide and Glycolic Acid

In the field of skin care, a reasonable combination of various ingredients can improve the skin care effect, but the compatibility between ingredients is crucial. Here is an analysis of the compatibility of salicylic acid, niacinamide and glycolic acid.

Salicylic acid, a beta-hydroxy acid, has excellent fat solubility, can penetrate deep into pores, remove blockages, has significant effect on skin problems such as acne and acne, and can also promote the metabolism of the stratum corneum, making the skin smooth and delicate.

Niacinamide, a derivative of vitamin B3, is widely used in skin care. First, it can effectively inhibit the transmission of melanin to keratinocytes, thereby brightening the complexion and improving dullness; second, it can enhance the skin barrier function, reduce water loss, and keep the skin hydrated; third, it has a regulatory effect on sebum secretion and helps improve the condition of oily skin.

Glycolic acid, as a member of the α-hydroxy acid family, has good water solubility. It can remove aging keratin accumulated on the surface of the skin, promote cell renewal, improve skin gloss, and stimulate collagen production to enhance skin elasticity.

When exploring the compatibility of these three, salicylic acid and nicotinamide are generally safe to match. The two cooperate. Salicylic acid mainly focuses on pore cleansing and exfoliation, while nicotinamide is responsible for brightening the skin tone and strengthening the barrier, which complement each other. However, some people with sensitive skin may experience slight discomfort in the early stage of use, such as short-term tingling and redness. This is the skin adaptation process. When using, you should try it on a small area first. If there is no adverse reaction, then expand the scope of use. It is recommended to start with low-concentration products.

Salicylic acid and glycolic acid are both exfoliating ingredients, and the same use will significantly enhance the exfoliation strength. For oily skin with good tolerance, when specific skin problems such as severe acne and heavy exfoliation, low-concentration short-term combination may achieve good results, which can improve the skin texture more efficiently. However, for medium-dry and sensitive skin, the same use of the two can easily cause excessive dryness, desquamation, and even inflammation of the skin. Therefore, the combination of such skin types should be avoided, or the frequency and concentration of use should be strictly controlled under the guidance of professionals.

Niacinamide is usually safer when paired with glycolic acid. Niacinamide can relieve the possible irritation caused by glycolic acid to a certain extent by virtue of its properties of enhancing the function of the skin barrier. However, when high-concentration glycolic acid products are combined with niacinamide, some people will still experience intolerance. Therefore, it is also necessary to conduct skin tests first, starting with low concentration and low frequency.

To sum up, although salicylic acid, niacinamide and glycolic acid have their own skin care advantages, when using them together, it is necessary to fully consider your own skin type. In order to ensure the safety and effect of skin care, it is recommended to consult a professional dermatologist or beauty consultant for the first time to obtain appropriate use suggestions according to personal skin conditions, so as to achieve the ideal skin care effect while avoiding skin damage.
