Silicone Enhancers is rated 4.4 out of 5 by 56.
Rated 5 out of 5 by from Lumpectomy? try this ! Following a lumpectomy 8 years ago I have been left with a 5 inch indentation across my right breast above the nipple. Despite a padded bra this has always shown through my clothing and worsened over the years. I am reluctant to have reconstructive surgery as I do not want to risk my health or reactivating the cancer cells. The M&S bra fitter today suggested inserting one of the silicone enhancers in an attempt to push the breast upwards and to try and even things out. I tried this but actually ended up inserting it ABOVE rather than below the breast and it works a treat, so comfortable too. I have yet to put it to the 'activity' test but if it moves I guess I can always use some beauty tape to help keep it in place.

Rated 5 out of 5 by from My best friends! I have used these breast enhancers for years and LOVE the boost they give my, otherwise, small chest! I am usually a size 34a but these increase me to 34b. They fit into any type of bra, I personally think they work really well with M&S Louisa Lace bra. Together, they give me a fabulous pert and full look. They fit beautifully and give me confidence to wear clothes that would usually emphasise my lack of cleavage. I would recommend wiping them with a damp cloth after each wear and dry to prolong their life. I wear mine every day and they usually last 15-18 months. I always apply perfume etc BEFORE putting the enhancers in.

Rated 5 out of 5 by from Just what I needed I had a lumpectomy many years ago and over time as the internal scarring in the affected breast has subsided I've ended up with one breast quite a lot smaller than the other. As a result a cup size that is correct for the larger breast is wrong for the smaller. In addition the imbalance means that my bras are pulled to one side and the band can dig in quite painfully. I saw these enhancers in store some time ago and thought they might be worth a go. They were out of stock when I went back, so I ordered on line. I've been using an enhancer on the affected side for just about a week and it has eased the problem considerably. The item is very comfortable, doesn't make me sweat as I feared it might and it feels very natural. I only use one enhancer at a time of course, but it means I have a spare and one can be washed while I'm wearing the other. I would definitely recommend for any ladies who have a similar problem.

Rated 4 out of 5 by from Could Be Cheaper? These were very comfortable and were perfect for my bras. As I have a large sort of body (don't laugh) I don't feel comfortable with having a lack of upper body cleavage so I ordered these for my bras. They were very good fit, enhanced perfectly, amazing boost of confidence for me, and also got a load of comments from my friends! The only thing is that the price is way too high for these, you could easily buy some cheaper ones from other stores. This is the same price as a two pack bra! I wouldn't buy it again, but I would recommend it to a friend and I will keep on using them until I need to get some new ones.

Rated 4 out of 5 by from Did what they were meant to After having my son whom I breastfed I was left with one breast larger than the other, hence the chicken fillets!! They're comfortable to wear and give a natural shape, however are pricey for what they are, cheaper than breast surgery though! They can make you a bit sweaty, good product over all and would recommend to a friend!

Rated 5 out of 5 by from my new bust enhancers This is a quality product with a very realistic feel. It would be ideal for someone, maybe a young person with a slender figure, looking for something to boost their self-confidence.

Rated 4 out of 5 by from Exactly what I needed If I could afford cosmetic surgery, my breasts are the one (sorry, two!) things I would have done, as the fact that there's a good cup size difference between them has bothered me alll my adult life - I don't care that it's very common, I still hate it! Buying these enhancers has at last made me feel more relaxed and confident about how I look, and what I wear. I would definitely recommend them, very comfortable, easy to wear and competitively priced.

Rated 5 out of 5 by from Perfect solution These enahancers are perfect for those of us who have one breast a cup size bigger than the other! I wear one in the smaller cup, they sit nicely in any bra, and don't move around. They're very comfortable, they can't be seen and they allow me to wear whatever I like without feeling 'odd'.
