The exact number of days it takes for plantar warts to clear up after applying retinoic acid cream varies on an individual basis related to the size of the wart, among other things. Smaller warts may be eliminated in about 7 to 10 days, but if the warts are large they usually cannot be completely eliminated by Vitamin A. Plantar warts are proliferative, warty skin conditions caused by HPV (human papillomavirus) infection. Vitamin A cream is a derivative of vitamin A and has some anti-proliferative and anti-keratinizing properties. For plantar warts that are verrucae or lesions with more pronounced keratotic hyperplasia, treatment with retinoic acid cream can help eliminate the warts. When treating plantar warts, there is individual variation in how many days specific warts can be eliminated by topical application of retinoic acid cream. If the warts are small, they may be eliminated in about 7 to 10 days. However, if the warts are large, it may not be possible to eliminate the warts with this medication alone, and it is recommended to combine the treatment with liquid nitrogen freezing, laser or surgery, as prescribed by your doctor. It should be noted that sunlight can aggravate the skin irritation caused by retinoic acid, so retinoic acid cream should be applied most preferably in the evening and before going to bed, and the treatment process should be avoided by avoiding sunlight, or using shade measures. It is recommended to go to the dermatology department of the hospital in time, do not use your own medicine, so as not to delay the condition.
