When can I apply makeup after receiving a hyaluronic acid injection?

　　The hyaluronic acid injection, commonly known as the "water light needle," typically uses microinjections to deliver hyaluronic acid directly into the dermis to improve skin condition. The general reference price for a water light needle treatment is 1,600-5,000 yuan per session, and visible improvement is usually observed after approximately 2-4 weeks. Typically, makeup can be applied 3-5 days after the injection, although the exact timing may vary.

　　If the individual's skin recovers well after the water light needle injection without experiencing adverse reactions such as redness, swelling, pain, or itching, and the cosmetics used are mild and non-irritating, free from potential allergens like alcohol or fragrance, makeup can generally be applied around 3 days post-injection. For individuals with weaker constitutions or slower skin recovery, it may take about 5 days before makeup can be applied.

　　After receiving the injection, it is important to keep the injection site clean to avoid infection. Contact with water or cosmetics on the injection site should be avoided for the first 24 hours. After the injection, the skin may experience slight redness and swelling, which is a normal phenomenon. Medical cold compresses or ice packs can be used to alleviate swelling and discomfort.

　　In daily life, a light diet is recommended. Additionally, strenuous exercise should be avoided, and adequate rest is advised to facilitate recovery.
