Here is an interesting thought-baking soda for acne. Does it really work? If so, it would definitely be a very cheap alternative.
Pros
It cleans the skin well and it makes the skin feel soft. It also helps get rid of mild acne very well, and it has helped with blackheads even and it makes the skin glow.
It is a very inexpensive solution, as already mentioned above. It also is very easy to apply and the texture of it can provide you with the right amount of exfoliate for your skin.
Cons
It could cause a burning or irritating feeling on someone with sensitive skin. It also can cause irritation even on normal skin if you rub it too hard into the skin. It also can sting if you have open wounds or sores on your face.
It sometimes is hard to wash baking soda off your face. It is a bit grainy too-not as soft as traditional cleansers.
Instructions
Using baking soda on your face for acne is most effective when made into a paste. You would add equal amounts of water to baking soda. It helps if you apply a moisturizer on afterwards, and one all natural solution would be a dab or two of olive or almond oil.
Using baking soda would probably work best for people with oily skin. However, it can be used with caution on normal and combination (some oily/some dry) skin.
If you want to try other ingredients with baking soda you might want to try honey, lemon juice, rose water, and brown sugar. This makes a nice facial scrub. You would mix the ingredients together in moderate proportions and then let sit on your face for 10 minutes.
You would then scrub your face for two minutes. After that you would then rinse/take it off.
