Can tretinoin cream remove freckles?

In general, tretinoin cream has a certain effect in removing pigmentation spots; however, the specific results may vary among individuals and should be used under the guidance of a doctor.

Tretinoin cream accelerates the shedding of the stratum corneum, removes old skin cells with pigmentation, and reduces pigmentation spots. Tretinoin cream can affect melanocyte function, reduce melanin production, inhibit tyrosinase activity to further decrease melanin formation, and stimulate collagen production, improving skin elasticity and structure, thereby reducing pigmentation caused by skin aging.

Before applying tretinoin cream, thoroughly cleanse the face to ensure the skin is clean and free of dirt. Use a cotton swab to apply an appropriate amount of the cream gently onto the affected areas. Avoid applying it around the eyes, mouth, nose, or other sensitive areas, and avoid extensive application. Tretinoin cream may increase the skin's sensitivity to ultraviolet light; therefore, sun protection measures should be taken during use, such as avoiding direct sunlight or using遮光 measures.

Note that tretinoin cream is somewhat irritating and photosensitive. Redness, dryness, and peeling may occur when first used. Follow medical instructions during use, start with a low concentration, gradually build skin tolerance, and avoid application during daytime to prevent ultraviolet light from exacerbating skin reactions. Additionally, pregnant and lactating women should avoid using tretinoin cream to prevent potential risks to the fetus or infant. Extra caution is required during use. If severe adverse reactions occur, discontinue use immediately and consult a doctor.
