Pros: Works for sensitive skin Proven results Natural ingredients Cons: Takes at least 3 weeks to see results Frequently Asked Questions Do last serums really work? If you apply the serum as directed, it results in thicker and longer lashes by hydrating and volumizing lashes and stimulates hair follicles to encourage more hair growth. This creates fuller and longer eyelashes and eyebrows. Are last serums bad for you? When used properly, eyelash serums are safe for most skin types. Those with underlying conditions, however, should consult with their doctor. The most common side effect of using eyelash serums is irritation and redness of your eye and skin around your eyelids. If you experience side effects, stop using the serum immediately. Are lash serum results permanent? Last serums work by boosting the length and thickness of your lashes as they grow. When using the serum, it stimulates your hair follicles to encourage growth so they grow to a longer length than your natural lashes. If you stop using the serum, however, new eyelashes don’t benefit from the formula’s ingredients, and the result is a shorter, natural length.
