You will find inside your My L-HA Booster box, around the ampoule, a little plastic ring to break the ampoule without any risk. Break the ampoule, then put it all inside the My L-HA Booster serum. To make the product fall more easily, slightly tap on its bottom. Once the whole ampoule is on the serum, close it and shake it. Your serum is then ready to be used!
Be careful: 2 ampoules are necessary for each benefit.
Mix the ampoules you selected with your serum then use your My L-HA Booster under your daily face care on a perfectly cleansed skin. Only few drops are enough to cover face, neck and décolleté.
Suitable to every skin type, even the most sensitive ones. External use only.
Tolerance, innocuity and efficiency guaranteed.
To remember the concentrates you added to your serum, look at the left side of your My L-HA Booster box, INCI lists of the concentrates you selected are stuck.
