My first ever attempt at removing hair on my legs was with an epilator. That's the only device my mum allowed me to use, she went on as if a razor was the devil. I continued to use this method for years.
However, using the epilator gave me plenty of ingrown hairs which I undoubtedly picked at all the time which often lead to scars. I found 'Silkimiz' which is basically sand paper for your legs and removes hair when used in gentle circular motions. This wasn't great as the hairs started to grow back the next day, but is a great thorough exfoliation method.
I tried waxing a few times, but it's just too messy, the hair removal creams smell so bad I just can't bring myself to continuously use them.
I then decided to use razors "the devil device", however women's razors are TERRIBLE, the first time I used one I scraped a layer of skin off my leg. I scrapped that and opted for men's razors which I have been using for the past couple of years.
Personally I haven't found my leg hairs to have grown back thicker or darker because of using razors, I don't get any ingrown hairs but it is a bit of a pain to do it regularly, whereas with the epilator I did it every week or so.
However, now we have IPL (Intense Pulse Light) technology, which we can use at the comfort of our own home for permanent / reduction in hair removal instead of shelling out the £££'s for laser treatment at a salon.
I have been sent 2 kits to try, one is the E-one and one is the i-Pulse. Both of them claim to be better than each other and I am going to put them to the test. I will try one on the left leg and one on the right leg to see which preforms best. I will report back in a few months!
