Use once a week; unlike other IPL hair removal devices you only need to use SmoothSkin Pure Adapt once a week for 12 weeks to achieve permanent hair removal. Follow up with a treatment every 4 - 6 weeks. Your safety: Skin contact & skin tone sensors ensure our devices only flash when safe. As IPL technology works based on the relation between melanin in skin and hair it can be unsuitable for deep-skinned users & ineffective on users with light hair. Do not use IPL on dark brown or black spots including birthmarks, moles, freckles. Do not use on tattoos or permanent make up. See the chart below for suitability or contact us if you have any questions on compatibility. Always perform a patch test. Fast & safe for eyes; full body treatment in 10 minutes & more effective than laser at a fraction of the price; so safe you don’t need goggles.
