Applying lotion to your skin – as in on your arms, legs, or torso – isn’t usually an issue. Some people think that lotion makes a good lubricant, and this is where they run into problems. If the lotion you used was not actually created to be used as a sexual lubricant, you can cause serious irritation to the natural pH and hormonal levels in your already sensitive vaginal area. The chemicals, and sometimes alcohol, can alter the bacterial/yeast balance, causing an overgrowth. You may have also inadvertently added additional bacteria to the mix.
Some women also think that applying lotion to their vaginal areas may help to soothe the irritation caused by a yeast infection. It will not. As a matter of fact, it will only make things worse. Your vaginal area is already red and inflamed and the external skin may already be very sensitive. Applying lotions not designed to provide comfort in this type of situation may cause burning and may even make your yeast infection worse.
Stick to traditional lubricants and treatments, your vagina will thank you.
