I have tried this personally and used my ring finger to apply
the product instead of the brush. I find I have better control this way.
This little magic works on under the eye bags and fine wrinkles.
Just make sure you apply on clean skin.
Apply your moisturizer well before and allow it to penetrate till there is no tackiness on the skin.
Use minute amounts, otherwise you get white deposits.
Once dry (5minutes) blend the edges with q-tip.
Do NOT use cover up over the FirmX
You can use face powder to blend the colour.
