On the safety of eicosanoic acid for the face
The world's opinion on skin care is often used for fruit acid. Eicosanoic acid has attracted much attention in skin care, but its safety for the face is divided, and it needs to be explored in detail.

Fu eicosanoic acid is active and has the ability to loosen the stratum corneum of the skin. Moderate use can help keratin renewal, make the skin glow, and can improve the skin's absorption of other things. However, it is highly acidic, and if the concentration is too high and used improperly, it is also easy to cause skin damage.

Looking at the structure of the skin, its outer cuticle barrier, if it is excessively damaged, the skin is prone to sensitive appearance. If the concentration of eicosanoic acid reaches 20, when applied to the face, if the skin is already delicate, or if it is used too frequently, it will often cause the skin to redness, tingling, itching, and even molting.

Furthermore, individual skin has different tolerance to eicosanoic acid. Oily skin or good tolerance, it is slightly easier to adapt to eicosanoic acid; while dry and sensitive skin, the stratum corneum is already weak, and it may be difficult to bear this concentration of fruit acid.

Therefore, those who want to use eicosanoic acid on the face should be cautious. Try it on the local skin first and observe its reaction. And you need to control the frequency and duration of use reasonably according to your own skin characteristics. When using it for the first time, it is recommended to use a small amount and low frequency, and then adjust it after the skin adapts.

In short, eicosanoic acid is not completely indispensable for the face, but whether it is safe or not depends on the user's understanding and use of it. Only with caution can you receive the effect of skin care and avoid the risk of skin damage.
