I was sent this product in exchange for this review. I have been a LiLash Eyelash Serum user and lover for years. Yes, years! I took some time off while I was pregnant and breastfeeding. And honestly, I missed my lashes during that time. But once I was ready to use the lash serum again, I was so happy to see my long and lush lashes return. I’m so excited LiLash reached out to me to send me more of this magic product that I already use and love.
Most asked question! Yes, #LiLashWorks! It’s the magic serum in a tube and honestly, I would not want to go without my LiLash. My lashes are noticeably longer and fuller. I get asked all the time if I’m wearing faux lashes or extensions. No, these are my real lashes, and they look amazing. I started noticing longer lashes just about 2 weeks in. I kept using it and my lashes were amazingly full and lush after a month.
What LiLash is and where to buy
The company name is Cosmetic Alchemy, and currently this is the only place where you can get authentic LiLash product.
You can tell counterfeits by checking for the hologram or the Authorized Stockist decal. See this page for more details. On that page, you can also find a list of REAL retailers that sell counterfeits for cheaper.
There are 2 sizes, 2 ml tube and 4 ml tube. The physical sizes of the 2 tubes are the same, but the amounts of product inside are different. I thought to purchase the 2ml tube as a travel size, but realized it’s actually the same physical size as the 4ml tube. I have used both sizes. The 2ml lasts me about 3 months, and the 4ml lasts me about 6 months! Since both tubes are the same in its physical size, getting the 6-month 4ml tube is much more cost efficient.
How to use LiLash for best results
It is recommended to apply LiLash serum to your upper lash line nightly for the maximum results. Your lashes are replaced by new lashes every 2-3 weeks. So if I stop using the serum for 2 weeks, the new lashes will grow to their normal length before use. So I make sure I never not go without LiLash for more than 2 weeks.
If I forget or skip a night or two of application, the next morning my lashes are still long and beautiful. So don’t panic if you have to skip a night or two. I think it varies and is different for each person.
Personal experiences and adjustments
I started LiLash treatment twice (once before pregnancy, and once after I was done with breastfeeding). The first time, I experienced slight irritation the first 2 times of applying LiLash. I reduced the amount of application to every other night instead of nightly. And then the sensitivity went away, and I started using it every night. The second time of treatment after breastfeeding, I just started using LiLash again with no irritation or sensitivity. Too much product could cause irritation. The applicator is a very thin brush, it looks like a liquid eyeliner brush. So apply the serum like you’re trying to draw the thinnest liquid eyeliner on your upper lash line.
Misconceptions and lifestyle compatibility
And don’t worry, if you want to wear faux lash or lash extensions while using LiLash, it’s totally okay! Good old water, aka H2O. The most common skincare ingredient of all.
The water used in cosmetics is purified and deionized. Read all the geeky details about glycerin here >> An easy-to-formulate, commonly used, nice to have ingredient that’s also called pro-vitamin B5. Its main job in skincare products is to moisturise the skin. It’s a humectant meaning that it can help the skin to attract water and then hold onto it.
Another great thing about panthenol is that it has anti-inflammatory and skin protecting abilities. A study shows that it can reduce the irritation caused by less-nice other ingredients. Panthenol is also useful in nail and hair care products.
As for the hair the hydration effect is also true there. A little helper ingredient that is used to adjust the pH of the product. It also helps to keep products stay nice longer by neutralizing the metal ions in the formula (they usually come from water).
Ingredient overview and skincare context
It's an alternative, natural preservative that comes from radishes fermented with Leuconostoc kimchii, a lactic acid bacteria that has been used to make traditional Korean dish, kimchi. A non-essential amino acid that hydrates the skin. Simply alcohol refers to ethanol and it's a pretty controversial ingredient. It has many instant benefits: it's a great solvent, penetration enhancer, creates cosmetically elegant, light formulas, great astringent and antimicrobial.
The downside is that it can be very drying if it's in the first few ingredients on an ingredient list. Some experts even think that regular exposure to alcohol damages skin barrier and causes inflammation though it's a debated opinion. If you wanna know more, we wrote a more detailed explanation about what's the deal with alcohol in skincare products.
Arctostaphylos Uva-Ursi is a little plant with nice red berries that lives in the North and is also called bearberry or kinnikinnick. It contains arbutin, a skin lightening agent, in the leaves.
A semi-essential amino acid that helps in skin and hair. A non-essential amino acid that hydrates and supports collagen. Vitamin C derivatives like MAP are discussed for stability and absorption considerations, especially in the context of skin brightening and antioxidant benefits.
A traditional Korean medicine used for more than 2000 years. PCA stands for Pyrrolidone Carboxylic Acid and is found naturally in our skin. An essential amino acid that the body cannot produce itself but must be obtained from the diet.
It's the most commonly used version of pure vitamin E in cosmetics. It helps to set the pH and acts as an antioxidant in many formulas.
Potential side effects and safety notes
A synthetic prostaglandin analog can be effective for lash growth but carries possible side-effects and FDA warnings about ocular irritation and color changes. Monitor for irritation and reduce application if needed.
It’s important to use the applicator properly to minimize any risk of irritation and to avoid over-application. If irritation occurs, back off to every other night and gradually return to nightly use as tolerated.
