Lemon juice is a common household treatment for acne. It seems to have its benefits, which are shown below. How well does it really work? That is the main question you probably would ask.
Advantages
It is a very inexpensive solution. After all, lemon is a very common kitchen commodity. You might need to buy a bit extra but usually the cost of it is less than a dollar-or about a dollar.
Lemon juice works well because of the acidic nature of it. The juice acts as an astringent and it helps clean the skin pores just as any fancy facial cleanser would do.
It seems to do well for all kinds of pimples and scars. It even worked better for one person in particular who combined baking soda with it.
Lemon juice also seems to do an amazing job at healing red spots and healing acne. It also makes the skin soft and some people actually like the smell of it.
Disadvantages
It stings, but mainly this is the case with people who use it on an open wound. It also is slightly sticky for some people. It could dry out the skin if it is used too much or too often.
Conclusion
For most people it works very well. Generally using lemon juice does more good than harm. It is a great thing to consider.
