This whitish layer has formed on the tip of my penis in just three days. What is it?

Some background information: I'm 17 years old. I was my glans penis twice a day when I bathe. I am not sexually active. I previously had mild smegma, which gradually disappeared after regular washing. I noticed this white layer forming three days ago. What is it, and should I be worried?

The layering would seem to be rather unusual? How long ago were you first able to expose the entirety of your glans?
Have you tried applying a slight amount of baby oil to the layering?
What do you use when you wash your penis?

It could be comfortably done from around 2-3 years ago. No, I haven’t tried applying baby oil. Should I? I currently do not have any in my house at the moment. And I’ve been using Cetaphil Restoraderm (Pro Ad Derma) to clean it.

Stop using the cetaphil - it is probably not safe to be in contact with the very sensitive skin on the head of the penis. The oil you need is either baby oil or coconut oil that is for use on skin, rather than hair. All you need is a relatively small amount rather than saturating the head of your penis. Vary the way in which you sequence the cleaning - oil first then wash. Wash then oil, then wash again - that kind of thing. You should then notice which is the most effective routine to use.

Here is the full detail of cleaning from a medical source:

Properly cleaning your penis is the easiest way to remove smegma. Gently pull back your foreskin. Use a mild soap and warm water to wash the area that’s usually covered by your foreskin. Thoroughly rinse off all the soap and then gently pat the area dry. Pull your foreskin back over the tip of your penis. The simplest way to remove smegma is to adjust your personal hygiene routine. In men, that means properly cleaning your genitals, including around and under your foreskin. Your body produces a lubricant to help the foreskin retract. That lubricant can build up under your foreskin along with other natural oils, dead skin cells, dirt, and bacteria. That’s why this condition is less common in circumcised men. Properly cleaning your penis is the easiest way to remove smegma. Gently pull back your foreskin. If the smegma has hardened, you may not be able to pull it back all the way. Don’t force it, as that can cause pain and tear the skin, which could lead to infection. Use a mild soap and warm water to wash the area that’s usually covered by your foreskin. Avoid harsh scrubbing, as that can irritate the sensitive skin. If the smegma has hardened. Gently rubbing oil on the area before cleaning it may help loosen up the accumulation. Thoroughly rinse off all the soap and then gently pat the area dry. Pull your foreskin back over the tip of your penis. Repeat this daily until the smegma disappears. It’s important to avoid scraping the smegma with sharp devices or cotton swabs as that can cause additional irritation.
