What is the price per ml?
We only calculate where a size and price are both shown. LashViva and BlinkBliss are each $35 for 3 ml, about $11.67 per ml. Our Duo is $49.95 for two 3 ml serums (6 ml in total), about $8.33 per ml. Lash Fridays shows lash serum “from $59.99” in 3 ml or 5 ml without a price for each. If $59.99 is the 3 ml price, that is $20.00 per ml, but we could not confirm this. Their brow serum at $69.99 for roughly 3 ml works out near $23.33 per ml, and the $89.99 duo (about 3 ml per tube, so roughly 6 ml in total) near $15.00 per ml. Treat these as estimates, and check their cart.
Do both brands offer lash, brow and duo options?
Yes. Lash Fridays lists a peptide eyelash serum, a peptide eyebrow serum, and a lash and brow duo (their page mentions a 25% saving), along with a mascara serum. We offer LashViva for lashes, BlinkBliss for brows, and the Lash & Brow Power Duo. Our duo page says it combines both serums for longer lashes and fuller brows.
Which brand shows more ingredient detail?
Our product pages publish a full ingredient list, shown below for LashViva. The Lash Fridays pages we read name key ingredients but did not show a full list or concentrations, so we cannot compare them line by line. If you want the complete list, ask the brand or check the packaging.
LashViva: Aqua, Hyaluronate, Pentylene Glycol, Panax Ginseng Root Extract, Swertia Japonica Extract, Pumpkin Seed Extract, Acorus Calamus Root Extract, Panthenol, Serenoa Serrulata Fruit Extract, Biotinoyl Tripeptide-1, Myristoyl Pentapeptide-17, Oligopeptide-10, Tocopherol, Biotin.
What do the guarantees actually require?
Lash Fridays advertises a 60-day money-back guarantee; you request a refund or replacement within 60 days of receiving the order and return the unused portion. Ours is longer but more document-heavy: after 12 weeks of consistent use you send dated before and after photos within 4 months of delivery. It covers a first purchase, excludes shipping and allergic reactions, and applies only to products advertised with it. Neither covers change of mind.
Do they ship to Australia and New Zealand?
Lash Fridays says it ships free across New Zealand and also to Australia; it states orders ship within 5 business days. Our shipping policy describes Australia Post delivery within Australia and dispatch within 72 hours, with free shipping depending on current promotions. Eastern Curlew ships to Australia and New Zealand; delivery options, prices and times are confirmed at checkout, and free shipping is a promotion that may change.
What should you know about prostaglandins in NZ and Australia?
Prostaglandin analogues are used in prescription glaucoma drops. NZ Herald reported that Consumer NZ and a Wellington glaucoma specialist called for clearer risk warnings on prostaglandin-containing lash products sold over the counter (undated article; read it here). In Australia, the TGA’s evaluation report for a bimatoprost eyelash product describes treatment of eyelash hypotrichosis as a prescription medicine (AusPAR). Neither source is about Lash Fridays or LashViva.
Who is each brand best suited to?
- Lower price and a longer guarantee window: LashViva, in our view, on those two criteria.
- A 60-day guarantee and a larger review count: Lash Fridays, which cites 1,800+ reviews (their own figure, not verified).
- Free NZ shipping stated on the page: Lash Fridays.
- Brow and lash together: both offer a duo.
Our options: LashViva $35 · BlinkBliss Eyebrow Serum $35 · Lash & Brow Power Duo $49.95
Frequently asked questions
Is Lash Fridays prostaglandin-free?
Lash Fridays states on its lash serum page and FAQ that the serum has no prostaglandins, prostaglandin analogues or hormones, as published on 2 November 2026. We did not see that claim on their brow serum page. Check the label for the product you buy.
Is LashViva cheaper than Lash Fridays?
On published prices, yes. LashViva is $35.00 AUD for 3 ml; Lash Fridays shows its lash serum from $59.99 AUD and its brow serum at $69.99 AUD on 2 November 2026. Shipping, promotions and sizes differ, so compare the final checkout total.
Does Lash Fridays ship to New Zealand?
Lash Fridays says it offers fast, free shipping across NZ, and also ships to Australia. Delivery times were not shown on the pages we read. Eastern Curlew ships to Australia and New Zealand; delivery options, prices and times are confirmed at checkout, and free shipping is a promotion that may change.
Do brow serums contain prostaglandins?
Peptide brow serums are generally formulated without them, but only the brand can confirm its formula. Our product pages describe BlinkBliss and the Lash & Brow Power Duo as prostaglandin-free, the same as LashViva. Check the ingredient list on your pack, and ask us at info@easterncurlew.com.au if you need confirmation before buying.
How long does a lash or brow serum take to work?
Lash Fridays says most customers notice a change in 4 to 8 weeks. Our directions for LashViva ask for 12 weeks of daily use. Hair growth varies, so photograph your lashes or brows at the start and judge at the end of the full period.
Is a lash and brow duo worth it?
If you want both, a duo can cost less than two singles. Ours is $49.95 for two 3 ml serums versus $70 separately. Lash Fridays’ duo was $89.99 for about 3 ml per tube, with a 60-day money-back guarantee, and was shown as sold out when we checked (as published on its page, read 2 November 2026). Compare per-ml cost and guarantee terms rather than the headline saving.
What we left out and how we compared
We used only prices, sizes, ingredients and claims visible on each brand’s own pages on 2 November 2026. We did not test products, compare review scores, or use percentage-improvement claims for either brand. Lash Fridays’ NZ-specific site and shipping policy were not read, so NZ pricing in NZD is not shown. Corrections: info@easterncurlew.com.au.
