Removing Dark Spots Naturally
There are a number of remedies, all natural, to remove dark spots from the skin. Some of these include aloe vera gel, milk, apple cider vinegar and extract of green tea. I can't vouch for any of them, I'm afraid to say, but I'd be willing to give it a go as none of these are harmful.

How Does Aloe Vera Work To Remove Dark Spots
I do have a dark spot on my face, due to overdoing it with the sun. (I'm a sun worshipper). So from tonight I am going to try one of the above, probably the aloe vera, and I'll report back. Aloe vera has a substance called Aloin, which is a depigmenter (Is that even a word?) and putting it on the affected area every night might see the dark spot disappear or certainly lighten up.
Apple Cider Vinegar for Dark Spots
Apple cider vinegar seems to be great for everything and not least for getting rid of dark spots on the face, supposedly. I've just applied some to my skin and by the time I'm finished this blog I'll give you my verdict. I simply poured out some apple cider vinegar onto my hand and then dabbed it on the dark spot. I suspect you'd have to do this continously for a number of days or weeks!
Removing dark spots on the skin with milk
Milk? Well ask Cleopatra! She regularly had baths of milk to help with her skin and keep it blemish free. I'm not going to try this one out as I'm not the best for drinking or ingesting milk. Apparently, it's the lactic acid in the mild that helps to lighten sun spots or dark spots. With a cotton bud dipped into the milk, dab it on the spot. This you should do a few times a day. It will probably be more than a week before you see results
Extract of Green Tea for Dark Spots
Again, I don't know if this will work but it's worth giving it a go. Simply take a green tea bag, soak it in boiling water for a couple of minutes, drink the tea if you want, allow the teabag to cool and then apply to the dark spot, leave on for a couple of minutes (while you're drinking the tea). Do this for a number of days and see the results.
By the way, I've just checked that dark spot on my face. It's still there, I'm afraid. But as I said before, I'd say one would need to apply the apple cider vinegar a number of times and for a number of weeks to get rid of the dark spot
