I tried various acne regimens for decades, until I found that a single drop of castor oil per day was enough.

Are you tired of pathogens invading your skin?  Plants have been fighting this battle since before the dinosaurs.  There are many antiseptic oils to choose from, but one offers the best mix of effectiveness, price and comfort.

The castor bean holds the Guinness World Record for deadliest plant.  Not only does it contain ricin, it also produces castor oil, an FDA-approved natural preservative for food.  It's commonly used in skin, hair and lip products, also for wound treatment and as an anti-inflammatory.

There is no better barrier between germs and your skin, but people rarely use castor oil by itself, because it's too thick.  Spreading castor oil with a finger leaves a sticky shiny residue.  

Diluting castor oil reduces its antiseptic effectiveness.  However, there is a way to get castor oil at maximum strength without feeling oily.  Spread a single drop of oil on a shaving brush.  Then you can easily wipe the drop over your whole face.  

Brushes are good at spreading oil.  This is why one bastes a turkey with a basting brush.

Apparently spreading castor oil super-thin is a new idea.  When people try castor oil topically, they just glop it on.  That's bad for your skin, which needs to breathe.  For example, this woman found castor oil helpful despite using way too much.  Most people can't stand having their face coated like that.

Here is a 3-minute video showing how I do it.  It is the simplest skincare routine I've ever had.  The oil layer is invisible and comfortable.

Washing with soap kills germs once, but weakens the skin's protective oil barrier.  Apply a drop of castor oil afterwards for lasting protection.  

A 3 USD 100ml bottle of castor oil lasts months, and the shaving brush lasts years.  

I still have some scars, but the pimples are gone.  Allegedly castor oil reduces scars, and mine do seem smaller now.
