Can M2 Eyelash Activating Serum (EAS) cause skin irritations?

Since our serum is an active agent, slight redness of the skin above the lashes is possible in isolated instances. If you are affected by this, skip applying the Eyelash Activating Serum (EAS) for one day and then apply it every other day. We have observed that the skin adapts very quickly to the active ingredients and that any signs of irritation rapidly disappear.
