The shine is won in two stages. For immediate anti-sobbing, we get rid of obsolete epidermal cells that do not want to go away and dull the complexion. Exfoliation (mechanical or enzymatic) instantly makes a skin that is not smooth and regular, giving it the power to reflect light.

Bet with the two-in-one formulas: micro-particles provide a gentle exfoliation, and ad hoc active agents target the problem during the exposure time (cellular oxygenation for a boost of energy, anti-inflammatory action against the browning of fibers ). The brilliance is a complex phenomenon that requires several plans of attack, Lionel Benetti supplements these weekly exfoliations daily use of a care rich in vitamins C and E or antioxidants. The promise of reducing in a month what darkens the skin: redness, areas of darkness, dilated pores, desquamation.

Strobing, which is to accentuate the light on certain areas, gives glow and reveals a radiant face: "Very easy to carry out and wear in real life," explains Julien Michelet. He advises, too, regular exfoliations so that the make-up slides well on the skin. And to superimpose products whose materials are similar: either powdered illuminators on mattified complexion to the sun, for example, or wet illuminators on bare skin or liquid foundation . To place just on the salient areas - nose ridge, Cupid's bow, lion's wrinkle - and focus around the eyes, above the cheekbones and around the brow bone. Alarm clock effect guaranteed.

The colour ? Lighter than the foundation: off-white, subtle rosé or champagne. Last tip: "No make-up nude, too bland, rather strong points with a black mascara duo and liner or a beautiful lipstick. "

The dermatologist Nadine Pomarède

She advises to associate superficial peeling (two appointments separated by two to three weeks), for radiance, and good nutrition, to act in depth. The right combination to revive blood vessels in the dermis. "Polyphenols and flavonoids boost microcirculation. Tea, grapes and berries, including blueberries, raspberries and blackcurrants, are drunk. "

We also target beta-carotenes, beneficial on the skin: red and orange fruits and vegetables, but also green, where carotenoids are masked by chlorophyll. It's good because the changes on the skin are not fast: "The cells of the epidermis take four to six weeks to go to the surface. Last advice: it is the regularity which prevails.
