An eyelash refill is recommended about 3 weeks after the intial session in order to refresh the appearance and maintain fullness. Waiting too long for a fill might warrant a full set again.
Here's my work in progress on a client who waited just a little under four weeks. These lashes have stayed on nicely - but it was definately time for a fill.
The white dressing around the eyes consists of some tape and an anti-wrinkle gel pad that feels like a cool sticker. It's infused with vitamin e and collagen to refresh the delicate tissue around the eyes, and it helps prevent the bottom lashes from getting stuck to the top lashes.
Once the eyelash refill is complete, the client's lashes are restored to its abundant volume. And then as our natural lashes fall off and grow back, we'll do this again in another 3 weeks, so is the cycle of the curious and beautiful eyelash.
