Dont go right up to your eye line stay below the crease, personally for me i dont use setting powder in a ‘baking’ way as it always creases, i just very lightly go over with a powder, staying away from the natural crease, also if im going full glam i actually use an eyeshadow primer under the eye not a concealer🥰🌹
Prep your under eyes with a hydrating and plumping eye cream first and give it time to fully absorb into the skin.
Apply concealer in light layers and build up if needed. I place a couple of small swipes or dots on the inner and outer corners and blend out with a concealer brush or damp beauty blender, starting from inner corner and working outwards. I usually use the pointy end of the sponge to smooth out the concealer and remove creases before setting with powder.
To set concealer, I put a little powder on a triangular powder puff, rub it together n the puff, then tap off the excess on the back of my hand and pat and press on the under eye with the pointy facing upwards. Next, I sweep away any excess with a small powder brush.(edited)
