Lan Kwai Fong’s Smile Center offers fast, painless and affordable teeth whitening treatments. It only uses peroxide-free products, so the whole experience is totally safe for clients. It uses an LED lamp (which doesn’t transmit warmth or UV light)as a whitening accelerator, so you can expect your teeth to be two to ten shades whiter in under an hour! Results are immediate and can last up to three months. All of its products and LED lamps are certified by the US Food and Drug Administration (FDA) and meet the EU and Swiss safety standards on cosmetic teeth whitening.
