You may not have applied enough product. The next time around, try adjusting the amount by applying more product as needed. Make sure to layer gently without rubbing.
You may be over-blending. Make sure to glide product on in 2-3 gentle sweeps and gently blend at the edges. Do not tap or rub.
Uneven application or facial movements during the setting process will affect your eye bag reducing results.
Make sure to give enough time for the product to set. Make sure that you are covering the entire under eye bag area with product. Applying product to too small of an area will affect your eye bag reducing results. Instead, start from the inner eye corner and spread towards your crow’s feet, extending fully to your hairline and cheekbones.
