I like to use a process with 3 steps:
1) Wet a round cosmetic pad and put a dab of chlorhexidine/ketoconazole shampoo (eg. ketohex, curaseb ) on it , and wipe out both wrinkles with it
2) Use a second wet round cosmetic pad to wipe out the wrinkle
3) Use a third dry round cosmetic pad to dry out the wrinkle
4) If it's really red like now, put on some diaper rash creme like desitin or sudocreme on wrinkle (optional, just when it's really red )
I repeat this every 2 days for my dog, but while it's red do every day.
@Hankster likes to wipe the wrinkles with some colloidal silver on a microfiber cloth, and also puts on some aloe gel for soothing.
