Almost 20 years old and no facial hair at all?

Dear googleflake

Thanks for the question. In addition to men who do not have any beard at all, those men who have patches of non-hairy parts on the beard and moustache regions  or who have a scattered beard can have a beard transplantation operation.
In addition to them, beard transplantation can also be performed with those men who have scars on their face as a result of pimples, burns or incisions, for the purpose of hiding these scars from view.
Those men who like the appearance of a stubble beard and want to grow their sideburns but who have a scattered and sparse beard often undergo a beard transplantation operation, too.
Beard and moustache transplantation can also be performed without experiencing any beard loss for the purpose of modifying the pattern of the beard and moustache. I wish you all the best.

Facial hair growth is a genetic trait.  If you have very little facial hair there isn't much you can do to increase the growth.

Googleflake, Beard growth is under the influence of DHT which turns on the secondary sexual characteristics in young men at puberty causing the beard, chest, and back hair to grow. Whether you will grow hair will depend on your genetic inheritance so it is best to look at your male relatives to see what facial hair patterns are common. I would not recommend any oils or supplements because it is unlikely they will help with beard growth.The most effective way to create a natural beard is through facial hair transplantation. Research is advised as this is a very visible area to transplant. 

You have two options.  1) Accept the lack of growth and change your outlook. See your smooth face as an enviable trait. People spend great energy to look and feel young. Maybe just embrace it!   2) Try different techniques to get hair. The best option is 5% minoxidil twice daily. For scalp hair growth patients, we recommend patients keep this off their face because it stimulates facial hair growth. In your case, this could be a positive.  As a last result, you can transplant to the beard from the back of the head. I wouldn't rush to this at this time as you may be a late bloomer.  Best of luck!

Hello in California,First of all, don't waste your money on oils, lotions and supplements. None of them work even one little bit, as you are finding out.  Only Minoxidil and Finasteride have documented evidence for increasing hair growth, and primarily on the scalp.  Some studies have shown benefit from using Minoxidil on the beard, but the hairs are often very fine and light.Facial hair is present in women, babies and children, but it is vellus hair which is fine, short and clear and only visible if you look really, really closely.  Under a combination of male hormones and genetics (family history) vellus hair changes into thicker, darker and longer terminal facial hair in men, starting in puberty and continuing into the early twenties.   Even at age 20, it is possible that you will develop more facial hair over the next 5 years.  There is no way to predict for sure, but have a look at your male relatives (brothers, father, maternal and paternal grandfather, uncles...) to get an idea of the genetics of facial hair in your family.  If none of them have a lot of facial hair, then that is probably what is in store for you as well.  You can choose to have a beard transplantation procedure and you will most likely be very happy with the results.  The only downside to doing it at such a young age is that (a) if you wait longer and get some natural hair growth, you may be able to get away with a smaller transplant, and (b) there's a chance you may start to get hair loss in your scalp in the next 10 years, and you may decide that transplanting your balding scalp may be more important than the beard, and that you need all the grafts you can get.  Basically, you just have to figure out what your priorities are.  Again, looking at your male relatives will help.  Are many of them bald?  Did they start to lose their hair at a young age?If you decide to come in for a consult, bringing photos of your male relatives will be helpful.
