Summarize the following:
As previously noted, using mascara can give you the appearance of longer, fuller eyelashes, but some standard mascaras can actually do more harm than good in the scheme of things. The best type of mascara to use for eyelash grown is a lash-enhancing kind, while lengthening mascaras are the best to promote the look of longer lashes immediately.  A lash-enhancing mascara contains special lipid complexes that are actually capable of strengthening your eyelashes as it coats them. Wearing this type of mascara is less likely to damage your lash line, but you should still make sure to clean it away gently to avoid accidental damage.  Volumizing or lengthening mascara can give you a great look, but if it does not contain lash-enhancing properties, using too much of it or using it too frequently can still cause damage to your lashes. While eyeliner spends less time clinging to your eyelashes than mascara does, it still touches your lashes at the root, giving it plenty of opportunity to help or hurt new lashes as they grow in. A "lash grower" liquid liner should be applied directly to the base of the lash line. The peptides in the product strengthen your lashes at the base. Lacquer is formulated to give your eyelashes more volume and shine without becoming clumpy. If your eyelash area looks especially vacant, you can swipe some on over your favorite mascara for an added boost. While lacquer does not damage eyelashes as much as a traditional mascara does, it can still have a negative effect if abused. For best results, use the lacquer over lash-enhancing mascara or primer. Instant lash cosmetics contain tiny synthetic lash extensions. As you brush the cosmetic over your natural lashes, these extensions are deposited on the ends, making your eyelashes look fuller and longer.  Some of these cosmetics also contain hyaluronic acid and vitamin E, so they condition your eyelashes while giving them an added visual boost. These cosmetics should only be applied toward the tip of your lashes, though. Applying them near the root can cause irritation, since the fibers can come loose and get into your eye. Some beauty salons now offer eyelash extensions. Synthetic lashes are individually glued in between your natural lashes, creating the appearance of a full, healthy lash line.  The process can take a few hours, but the results last for several weeks. You will also need to get a 30-minute touch-up every two to three weeks if you want to keep the look going. Sleep on your back to avoid accidentally pulling out the extensions. One downside of eyelash extensions is that, for some women, they can actually cause your own, natural eyelashes to fall out more rapidly and ultimately thin out. Another disadvantage of eyelash extensions is the cost. The procedure can set you back $300 or more. Fake eyelashes can give you the appearance of long, lovely lashes, but they usually need to be changed out daily and might cause long-term damage to your eyelashes if used too often. The part that causes the most damage is removal. As you peel the fake eyelashes away, you might take some of your natural eyelashes along for the ride. Since you have to change your fake eyelashes so often, this damage can seriously build up over time.

Summary:
Use a lash-enhancing or lengthening mascara. Swipe on lash-enhancing eyeliner. Paint on a lacquer. Try an "instant lash" cosmetic. Pay for eyelash extensions. Weigh the pros and cons of fake eyelashes.
