vasaline and baby oil are not good ideas for the glands penis. they can block skin pores and cause more skin redness
LENOVATE OINTMENT; LENOVATE CREAM contains betamethasone valerate equivalent of 5 mg betamethasone steroid ointment.
long term use of betamethasone steroid cream can decrease inflammation in an area, but can thin the skin and suppress immune response in the skin in the area.
if the red spots and eczema are not worrisome or symptomatic, then i would not stress about it and only treat it if and when it gets bad which may be never.
you should wash daily and retract the foreskin and wash with mild soap and water daily to keep the area clean.
you should wash your hands after using lenovate
better to use the vasaline or lanolin or thick moisturizers on your dry cracked heels and toes and elbows during the dry winters.
in the groin, often times with excessive moisture or heat, you can have an itchy fungal infection in your groin area. this would be best treated with an antifungal cream or powder or spray.
let me know if you have other questions.
