#2 Lemon

We all know that lemon is one of the most potent acids you can find naturally, and its astringent powers make it an important ingredient in a lot of mixtures. However, it is also known to be a great aid in combating blemishes, effectively blurring them, and also tightening any sagging skin! It is also useful for keeping acne flare-ups under control.

Despite this, you should never use it directly on your skin as a topical treatment! Freshly squeezed lemon juice is too acidic and it will damage your skin barrier, which in turn will have the opposite effect of what you are looking for: it is going to make your skin prone to sun damage due to being exposed, causing excessive darkening or lightening!

Despite all of this, you can still get the same sort of properties if you add lemon as part of your diet! You can either add it to your salads or your water or even include the peel in baked goods or other types of dishes. A 2014 study has proven the benefits of citrus peel when it comes to protection and prevention against cancer!
