How can I firm up the skin on my body? Quickshop 1. The skin on the body loses its firmness over the years. With time or after weight gain, the collagen fibres that once kept tissues firm become impaired, and irrespective of the area on your body, skin starts to slacken. Clarins founder Jacques Courtin realised that tackling skin firmness on the body improved the overall appearance. 2. Clarins' solutions for firmer skin To firm up your skin, start by exfoliating once or twice a week. Regularly using a body scrub will help boost the action of any products you apply afterwards. Try the Exfoliating Body Scrub for Smooth Skin with bamboo powder, or the Toning Body Polisher to gently brush away dead skin cells. As well as exfoliating weekly, apply a daily firming treatment if you want to regain definition. Whether you prefer a lotion, a gel, or a cream, there's a range of different textures to choose from. You might like to try the Extra-Firming Body Lotion or the Extra-Firming Body Cream. There are targeted products that tackle specific areas, too, such as the Bust Beauty Extra-Lift Gel. These products are highly effective on targeted areas. Finally, you can keep stretch marks at bay with the Tonic Body Treatment Oil, made from 100% plant extracts. As soon as you get out of the shower, apply a few drops of the oil to wet skin, gently massaging in before rinsing with cold water. The Tonic Body Treatment Oil is ideal for reducing the appearance of stretch marks, improving skin elasticity and sculpting your curves.
