Smudged mascara, sparse gaps, and lashes that vanish the moment you blink can make the mirror feel unexpectedly unforgiving. Sparse lashes and thin brows often need more than another coat of makeup.
The best lash serums at ulta vary by formula, size, and application details, so a clear comparison matters before you commit. Keep reading for practical guidance on sorting the options.
Key Takeaways
- Prioritize the ingredient profile, especially if you want a prostaglandin-free formula or have easily irritated eyes.
- Compare the serum size with the stated supply period, since a lower price may reflect a smaller bottle.
- Check the application instructions for nightly use, lash-line placement, and any required waiting period before makeup.
- Look for clear guidance on eye-area safety, including warnings for contact lens wearers and sensitive skin.
- Review the brand’s claims carefully, separating fuller-looking results from medically supported hair-growth claims.

The Ordinary Lash Serum, Peptide Formula
The Ordinary Multi-Peptide Lash and Brow Serum suits anyone who wants one formula for lashes and brows. Its peptide-focused positioning makes it a sensible choice for shoppers seeking a targeted, non-oil serum with a simple routine.
The 0.16 fl oz size keeps the package compact and easy to store, while the dual-purpose format can reduce clutter on your vanity. The limitation is equally clear: the small bottle may not suit anyone who prefers a larger supply or wants a formula with a named botanical ingredient.
- Brand:The Ordinary
- Product Type:Lash and brow serum
- Size:0.16 fl oz
- Ingredient Focus:Multi-peptide formula
- Application:Serum application
- Eye Area:Lashes and brows
- Additional Feature:Dual-purpose lash and brow use
- Additional Feature:Peptide-powered formula
- Additional Feature:Compact package size
-
Advanced Lash Serum, 3 mL
Choose this 3 mL serum if you want one product labeled for both eyelashes and eyebrows. The formula is positioned around thicker, longer-looking lashes and fuller-looking brows, giving your routine a broad focus rather than limiting use to the lash line.
Its larger size may appeal to shoppers who want more product than a miniature tube, and the lash-and-brow format adds practical flexibility. The main drawback is the limited product information available in the title, so the specific ingredients and application guidance remain unclear.
- Brand:Not specified
- Product Type:Lash and brow serum
- Size:3 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes and brows
- Additional Feature:Eyelash and eyebrow use
- Additional Feature:Longer-looking lash focus
- Additional Feature:Thicker-looking appearance
-
GrandeLASH-MD Serum, 1 mL
GrandeLASH-MD in the 1 mL size is a practical pick if you want a defined, shorter supply before committing to a larger bottle. The listing identifies it as a lash-enhancing serum and specifies a six-week supply, which gives your routine a clear timeframe.
The compact size works well for travel or first-time serum shoppers who prefer a smaller format. Its limitation is capacity, since the 1 mL bottle offers less product than the 2 mL version and is intended around a set supply period.
- Brand:Grande Cosmetics
- Product Type:Lash serum
- Size:1 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Six-week supply designation
- Additional Feature:Lash-enhancing positioning
- Additional Feature:Compact travel-friendly size
-
GrandeLASH-MD Serum, 2 mL
The 2 mL GrandeLASH-MD version makes more sense for shoppers who want the same named lash serum in a larger format. It focuses specifically on lash enhancement, keeping the product directed toward a single area rather than combining lash and brow care.
A larger bottle can provide a more convenient supply for an established nightly routine, while the cruelty-free designation may matter to shoppers who screen products by animal-testing policy. The tradeoff is that the listing does not provide ingredient details or a stated supply duration.
- Brand:Grande Cosmetics
- Product Type:Lash serum
- Size:2 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Cruelty-free formula
- Additional Feature:Lash-enhancing positioning
- Additional Feature:Larger size option
-
ForChics Prostaglandin-Free Lash Serum
ForChics is a strong fit if you specifically want a prostaglandin-free formula for thin-looking lashes. That ingredient distinction gives the product a clear place in a roundup, especially for shoppers who prefer to avoid prostaglandin-based lash products.
The formula is positioned to rebuild the appearance of thin lashes, so it speaks directly to a targeted concern rather than general lash conditioning. The limitation is that the listing does not state the bottle size, ingredient alternatives, or whether the product is intended for brows.
- Brand:ForChics
- Product Type:Lash serum
- Ingredient Focus:Prostaglandin-free
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Designed for thin-looking lashes
- Additional Feature:Prostaglandin-free positioning
- Additional Feature:Lash-focused formula
-
VieBeauti Lash Serum, 3 mL
VieBeauti’s 3 mL lash serum is suited to shoppers looking for a straightforward product aimed at longer, fuller, thicker-looking lashes. The listing keeps its purpose clear and focused, without adding brow care or a long list of specialized claims.
Its larger-than-miniature size gives you a practical amount for a regular lash routine, and the formula targets several appearance goals in one step. The drawback is a lack of disclosed ingredient information, so you cannot assess the formula’s active focus from the listing alone.
- Brand:VieBeauti
- Product Type:Lash serum
- Size:3 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Longer-looking lash focus
- Additional Feature:Thicker-looking appearance
- Additional Feature:Fuller-looking appearance
-
R+F Lash Boost Serum, 5 mL
R+F Lash Boost is the clearest choice for anyone who prefers a nightly application built into an established beauty routine. The 5 mL bottle is labeled for fuller, longer-looking eyelashes and brows, giving you one product for both areas.
Its larger size supports a more substantial supply, while the lash-and-brow format adds flexibility for a coordinated eye-area routine. The limitation is that the title does not identify the active ingredients or provide a stated duration, so the formula details are limited.
- Brand:Rodan + Fields
- Product Type:Lash and brow serum
- Size:5 mL
- Ingredient Focus:Not specified
- Application:Nightly application
- Eye Area:Lashes and brows
- Additional Feature:Fuller-looking lash support
- Additional Feature:Longer-looking lash support
- Additional Feature:Brow-enhancing use
-
Premium Lash Serum, Sensitive Eyes
This premium lash serum is aimed at shoppers seeking a formula labeled for sensitive eyes, a useful distinction if the eye area tends to react to strong or heavily fragranced products. Its core purpose is to support longer, fuller, thicker-looking lashes.
The 5 mL size gives the product a generous format, and the volumizing focus suits anyone who wants a more noticeable lash appearance. The limitation is the sparse listing information, since the specific ingredients, brand, and application schedule are not identified.
- Brand:Not specified
- Product Type:Lash serum
- Size:5 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Labeled for sensitive eyes
- Additional Feature:Volumizing appearance focus
- Additional Feature:Fuller-looking lash support
-
RapidLash Enhancing Serum, 3 mL
RapidLash suits shoppers who value a clearly stated two-month supply and a dedicated eyelash product. The 3 mL bottle focuses on lash enhancement, keeping the routine simple for anyone who does not need a brow serum.
A defined supply period makes it easier to plan replacements, while the 3 mL format offers more capacity than the smallest lash-serum bottles. The limitation is that the title does not disclose the ingredient focus or application schedule, so you will need the full product directions for those details.
- Brand:RapidLash
- Product Type:Lash serum
- Size:3 mL
- Ingredient Focus:Not specified
- Application:Serum application
- Eye Area:Lashes
- Additional Feature:Two-month supply designation
- Additional Feature:Eyelash-enhancing positioning
- Additional Feature:Dedicated lash use
-
UpNature Castor Oil Serum, 2 oz
UpNature is the natural-ingredient pick in this group, with a castor oil-based formula and a USDA Organic designation. The 2 oz bottle is particularly appealing if you prefer a larger format for lash and eyebrow care rather than a small precision tube.
The formula supports longer, fuller, thicker-looking lashes and brows, while the dual-area use makes it versatile. Its main limitation is the oil format, which may feel less convenient than a brush-on serum and can require more care around the eyes.
- Brand:UpNature
- Product Type:Lash and brow serum
- Size:2 oz
- Ingredient Focus:Castor oil
- Application:Serum application
- Eye Area:Lashes and brows
- Additional Feature:USDA Organic designation
- Additional Feature:Dual lash and brow use
- Additional Feature:Larger 2-ounce bottle
Frequently Asked Questions
How long does it take for lash serum to work?
Give most lash serums at least 8 to 12 weeks of consistent use before judging the result. Noticeable fullness may take longer because each lash follows its own growth cycle. Results can fade after you stop, particularly if the formula affects the growth phase rather than simply conditioning the lashes. Follow the brand’s maintenance guidance, and avoid applying extra product to speed things up.
Are lash serums safe for sensitive eyes?
Some are, but no lash serum is guaranteed to suit every eye. If you have sensitive skin, consider a fragrance-free formula with conditioning ingredients, and avoid formulas that contain ingredients you already know cause irritation. Do not continue using a serum that causes ongoing redness, swelling, pain, or vision changes. An eye-care professional can help you choose a safer option if you have allergies, dry eye, glaucoma, or another eye condition.
Can I use lash serum with contact lenses?
In most cases, remove contact lenses before applying the serum and wait until the product has dried before putting them back in. Check the label for the brand’s specific guidance, since formulas and directions vary. Apply a small amount to clean skin and keep the serum out of the eye itself. If your lenses become uncomfortable or your eyes stay red, stop using the product and seek professional advice.
Do lash serums contain prostaglandin analogues?
Some lash serums sold at Ulta contain prostaglandin-related ingredients, while others rely on peptides, botanical extracts, amino acids, or conditioning agents. You can usually find the ingredient list on the product page, packaging, or brand website. These formulas may produce more visible growth, but they can also carry risks such as irritation, eyelid darkening, or changes in the appearance of the area around the eyes. If you want to avoid them, review the full ingredient list and ask a pharmacist or eye-care professional about unfamiliar ingredients.
Can I use lash serum during pregnancy?
Ask your obstetrician or another qualified health professional before using a lash serum during pregnancy or breastfeeding. Cosmetic products can contain active ingredients with limited safety data for these situations. A cautious option is to postpone growth-focused formulas and use gentle makeup-removal habits to reduce lash breakage. Always follow medical guidance over marketing claims or online recommendations.
