The Platinum Long Lash Serum is stamped with Sephora’s clean seal of approval and backed by clinical results. After two weeks of use, patients in a clinical study saw a 25% increase in lash length. After a month? More than 70% lash density. After two months, there was an average 45% increase in new eyelash growth without the telltale darkening of skin and eye color that often comes with PGA formulas.

I also like the applicator — the sponge tip allows for really targeted application to areas that are particularly sparse.” After three months of use, the brand shares that an expert-graded study showed that 97% of subjects saw measured improvement in brow length and lash volume, and 90% agreed it restored the appearance of overplucked brows.

What are the potential side effects of prostaglandin eyelash serum?

According to board-certified dermatologist Blair Murphy-Rose, key ingredients in some lash serums, prostaglandins, or PGAs, are still mysterious. “Latisse contains a prescription-strength prostaglandin called bimatoprost that is known to stimulate growth though the exact mechanism is not well understood,” says Murphy-Rose. “Over-the-counter prostaglandin-based serums contain a weaker prostaglandin—the benefit to using a weaker prostaglandin-based serum is that the risk of side effects is also lower.” Hilal-Campo recommends avoiding PGAs entirely, which have been in the collective conversation lately (not to mention TikTok feeds) for their side effects—they often have powerful results—but with a risk. She notes that there’s a 20% chance that users of serums with PGAs will experience side effects. “It’s easy to identify PGAs in an ingredient list — look for ingredients with “prost” in them, like isopropyl cloprostenate,” she explains. “Keep in mind that because these ingredients aren’t regulated by the FDA like prescription-strength bimatoprost is, they may be stronger, and the risks of side effects could be even greater.” When side effects include fat atrophy and discoloration of the skin and iris color, it makes sense why clean formulas like the new brow and lash-enhancing Kosas GrowPotion serum and Dr. Lara Devgan’s Platinum Long lash serum are on the rise.

Do lash serums work?

With consistent use (i.e. weeks, and sometimes months)—and the right formula for your needs—you should be able to see positive results. “Lash growth serums work to strengthen, nourish and condition the eyebrow hairs which may give the hairs a thicker and healthier appearance,” Garshick explains. “By improving the health of the lash hair, it may also help make it less susceptible to breakage.” 

How do lash serums work?

According to Garshick, lash serums are powered by a combination of ingredients formulated to strengthen and support lash health. For example, peptides or biotin can help strengthen and thicken hairs, while antioxidants or hydrating ingredients like panthenol help nourish and condition each hair. Something like Latisse, on the other hand, works via a prostaglandin analog which “may help to increase the percentage of follicles and prolong the duration of anagen, which is the hair growth phase”—basically, stimulating the hair follicle to promote growth—Garshick explains. 

Do lashes grow back?

Eyelashes can grow back, though growth serums are mainly formulated to improve existing “lash thickness, volume and length,” Garshick says.

How long does it take for lashes to grow?

If only it were as simple as applying your eyelash growth serum at night and seeing visibly longer lashes come morning. In reality, Garshick explains that sometimes results can be seen as early as 2-4 weeks, though it will generally take several months for the full effect. She continues that “the results are maintained with continued use of the serum or product, though in many cases, once desired results are achieved, the number of applications per week may be reduced.”
