Base rating is an estimated baseline from the owner feedback we have available across Amazon reviews and any credible web sources we reviewed. GiftScore editorial signals (build, safety, longevity) are scored independently of that baseline — they reflect what owner feedback and product specs actually say about the product. Some signals are skipped when they don't fit the product type.
Intro
This is a compact, premium mascara from By Terry called Terrybly Growth Booster in the shade Purple Success. The listing frames it as a lengthening, clump-resistant formula with a growth-booster concept; real buyers tend to praise the color, hold, and non-clumping finish, but there are recurring reports about dryness and occasional dry or ineffective tubes. If you’re buying this as a gift, the two most important questions are whether the recipient wants a colored (plum) mascara and whether they care about cruelty-free sourcing and ingredient transparency — the listing and owner notes leave some of those details unclear.
What it is / first look
From the listing: By Terry Terrybly Growth Booster Mascara (8 ml / 0.28 fl oz) is presented as a lengthening, full-volume, clump-resistant mascara. The listing describes a few technology and ingredient claims — "Lumicoat Technology includes Xlash Complex Glycoproteins for a growth-booster action," "Collagen Hyaluronic Acid creates stronger and silkier lashes," and "Ultra-soft vegetables with film forming polymers deliver a curve and volumizing effect." It also calls out "extra-fine pigments" for an intense color and a lash-extension look.
Practical first look details buyers should know: the listing’s default color is Purple Success, the package dimensions and weight are small (2 x 2 x 2 inches; 0.32 ounces), and the product page oddly lists "1 A batteries required" as a specification. That battery note reads like a listing error — nothing in the product description explains why batteries would be needed for a mascara wand.
Who this is a good gift for
This mascara is a specific kind of gift — it’s not an every-person pick. Below are practical recipient matches and the assumptions you should check before you buy.
The creative makeup person who likes subtle color
Why: several owners praise the Purple Success shade as a deep, wearable purple rather than a bright, costume color. If the recipient likes slightly unconventional but still wearable makeup, this shade is a good fit. Assumption: the recipient is comfortable with non-black mascaras.
The lash-length fan who wants a growth-focused claim
Why: the listing markets a growth-booster approach (Xlash Complex glycoproteins plus collagen hyaluronic acid). Owners report noticeable length and some saying they saw new/longer lashes after weeks. Assumption: the recipient is open to a mascara that doubles as a growth-focused product rather than a pure volumizer.
Someone who hates clumps and raccoon eyes
Why: owners repeatedly mention no clumping, a separated-lash look, and good hold—some even call the wear similar to waterproof in rainy conditions while still removing cleanly. Assumption: they prioritize long wear and easy removal over dramatic falsies-style volume.
A person with sensitive eyes who still uses mascara
Why: several owners with sensitive eyes reported no discomfort or rash. Assumption: the recipient has general sensitivity but not a known allergy to unlisted ingredients — the listing does not provide a full ingredient list, so check sensitivities first.
In daily use
What owners report day-to-day: application tends to be buildable and non-clumping, producing length and a lifted curve rather than thick, heavy volume. Multiple owners say the lashes look individually coated and that the formula holds a curl well. Several users liked wearing it on lower lashes without smudging or flaking.
Removal: owners emphasize that it generally washes away easily with mild cleanser, contrasting it with waterproof mascaras that require more aggressive removers. Wear in wet weather: a number of users say the hold is very good in rain and light moisture, but the listing does not claim full waterproof performance — owners’ real-world reports reflect that nuance.
Daily longevity: usage reports vary. One buyer said a tube lasted a little over a month with near-daily use. Another owner described a couple-month lifespan. There are also at least one or two reports of a tube arriving effectively dried out and useless.
Materials & build quality
Listing claims: the product description calls out "Lumicoat Technology" with "Xlash Complex Glycoproteins," "Collagen Hyaluronic Acid," and "ultra-soft vegetables with film forming polymers" plus "extra-fine pigments." Treat those as manufacturer/listing claims — the listing names these ingredients/technologies but does not provide a full INCI ingredient list on the page provided here.
Real-world quality signals: owners praise color payoff, pigment intensity, and a brush/formula combo that avoids clumping. Several reviews note the formula runs on the drier side — some users like that because it helps hold a curl; others find it borderline too dry. There are mixed signals on batch consistency because a few buyers reported receiving a tube that was already dried out or ineffective.
Safety considerations
Eye safety and irritation: owners with sensitive skin and eyes frequently report no irritation or rash. At the same time, a few users mention a sensation of eye dryness while wearing it. Because the full ingredient list is not supplied in the listing data here, known allergy or sensitivity risk can’t be ruled out from the listing alone — confirm ingredients for anyone with prior reactions.
Cruelty-free and sourcing: owner conversations flag a significant concern — there are reports that By Terry sells in Mainland China and that entering that market can involve animal testing under current regulations. The internal notes include a reported statement attributed to the brand saying it made a decision to enter China and that it’s working with associations to try to change rules. If the recipient requires strictly cruelty-free cosmetics, verify the brand’s current policy directly before gifting; owners repeatedly raise this as a deciding factor.
Other hazards and oddities: the listing specifically enumerates a battery requirement of "1 A batteries required" in the specs. That appears incongruous for a mascara and should be treated as a listing anomaly — verify the product page or seller Q&A if the presence of batteries matters to you. Also, because the listing doesn’t publish a full ingredients list in the provided data, anyone with ingredient sensitivities is at risk unless you check current listing details.
Who should skip it
- If the recipient only wears black mascara — this is a plum/purple shade (Purple Success) and the listing emphasizes that color.
- If you need a guaranteed cruelty-free purchase — owner reports indicate the brand’s China availability has raised concerns, and the brand’s response (as reported by owners) acknowledges market entry and ongoing work with associations.
- If the recipient has a known allergy and you can’t confirm ingredient details — the listing doesn’t publish the full INCI list in the provided data.
- If you want a fail-safe long-lasting tube — while many owners report good wear, there are isolated reports of tubes arriving dried out or performing poorly straight away.
Verdict
Best gift fit: This feels like a considered, slightly luxe makeup gift for someone who likes lengthening mascaras, is open to a plum/purple shade, and values a no-clump, separated-lash finish. Owners praise the color, hold, and removal ease; a subset also reports longer-looking lashes after weeks of use — that’s the product’s selling point.
Buying risk: The main risks for a gift are a mismatch on color preference (not everyone wants purple lashes), potential cruelty-free objections raised by owner discussions about China distribution, and the lack of a full ingredient listing on the provided product data. There are also scattered reports of a dry or ineffective tube, so batch variance is a real-world risk.
Check before you buy (quick checklist)
- Confirm the recipient would like a purple/plum mascara (Purple Success).
- If cruelty-free status matters, verify the brand’s current policy and distribution publicly — owners report concerns about China market entry.
- Check the current listing for a full ingredient list if the recipient has allergies or prior reactions.
- Consider the return policy or gift receipt option in case the tube is dry or defective on arrival.
- Be aware the listing spec includes an odd "1 A batteries required" line — confirm with the seller if that worries you.
Bottom line: a good-match gift for the right person — notably someone who likes subtle color shifts, length over heavy volume, and a clean, non-clumpy lash look — but check cruelty-free status and ingredient transparency before wrapping it as a present.
Frequently asked questions
Is this mascara cruelty-free?
Owner feedback flags concerns: buyers report that By Terry sells in Mainland China and that selling in that market can involve animal testing under local rules. The internal notes include a reported brand statement acknowledging its China entry and efforts to work with associations; verify the brand’s current policy on the manufacturer’s site or product page before buying if cruelty-free status is essential.
Will this smudge or flake during the day?
Multiple owners report good all-day hold with minimal smudging or flaking; some say it performs similarly to waterproof products in rain but still removes more easily than typical waterproof formulas. The listing itself claims a clump-resistant finish.
How long does a tube last with daily use?
Owners’ reports vary: one buyer said a tube lasted a little over a month with near-daily use, another reported it lasted a couple of months. There are also isolated reports of tubes arriving dried out and ineffective, so lifespan may vary by batch and usage.
Does this irritate sensitive eyes?
Several owners with sensitive eyes reported no discomfort or rash while using this mascara; at least one user mentioned a feeling of eye dryness. Because the listing does not provide a full ingredient list in the supplied data, check the current product listing for ingredients if the recipient has known sensitivities.
What color is "Purple Success" in practice?
Owners describe Purple Success as a deep, true purple (plummy) rather than a bright or overly aubergine shade. The listing also cites "extra-fine pigments" for an intense color payoff.
Why does the product spec say batteries are required?
The listing includes a "1 A batteries required" line in the specifications. That appears incongruous for a mascara and likely is a listing error; confirm with the seller or current product page if battery information matters to you.
