(Source: ABC News) Long, beautiful lashes are highly coveted, but extensions cost around $300 and $75 more per touch up. Many lash growing serums have been banned from the market for containing dangerous chemicals, but one brand, Renew, has been all-natural from day one and is highly effective. So, for filling out sparse lashes, forgo expensive extensions and try Renew Eyelash Revitalizer—a miracle-working serum that promotes fuller, supple eyelashes for a more glamorous look. You will begin to see results in three to four weeks and at $80, it's a bargain for what it achieves. And if the salon has left your brows over-waxed, Renew Eyebrow Revitalizer ($115) helps promote healthy, supple eyebrows allowing for the design or re-design of eyebrows. Apply daily (once in the morning and once at night) to your brows and in 4-6 weeks they'll be noticeably fuller and healthier.
