Buying RevitaLash Advanced Eyelash Conditioner? Compare by the Month

Using each retailer’s own supply estimate, SkinElite’s 3.5-milliliter (mL) tube costs $25.33 a month, while Dermstore’s 2 mL tube costs $33.33 – here the bigger tube is the cheaper month. For the Advanced Eyelash Conditioner RevitaLash makes, each day takes one thin stroke per eye, then a short wait while it dries, says SkinElite’s product page. That leaves two things to settle before you pay: the size, and whether the label rules you out.

The label’s cautions rule out five groups and advise against use with dry eyes, eye infections, styes or any other eye-related disorder.

RevitaLash Advanced Is a Once-a-Day Lash Conditioner, Oil-Free and Extension-Safe

RevitaLash Advanced is sold as an eyelash conditioner, a cosmetic for how your lashes look. SkinElite’s listing calls it “oil-free and safe for use with eyelash extensions.”

On results, Amber Spa’s listing gives “survey results from an independent 6-week consumer study including 63 participants.” In it, 98% reported improved lash appearance, roughly 62 of the 63. These are self-reported survey results, not measurements.

The 3.5 mL Tube Costs 13% Less per mL Than a One-Time 2 mL Order

If you’ll buy once and use it for more than three months, the 3.5 mL tube is the better buy. If you’ll subscribe, Dermstore’s auto-replenish costs less a month at the same rate of use. Every listing below was checked on 2026-10-26, and the rows run from lowest to highest price per mL.

Retailer	Size (mL)	Price (2026-10-26)	$/mL	Supply, per the page
Dermstore, auto-replenish	2	$85.00	$42.50	3 months = $28.33/month
SkinElite	3.5	$152.00 (shown sold out)	$43.43	“6 month supply” = $25.33/month
Dermstore, one-time	2	$100.00	$50.00	“3 Month Supply” = $33.33/month
Amber Spa	2.0	$100.00	$50.00	about 3 months = $33.33/month
Amazon	about 0.74–1.03 (0.03 fl oz, rounded)	$59.00	about $57–$80	not stated

Here is the gap: $43.43 ÷ $50.00 = 0.87, so the 3.5 mL tube costs about 13% less per mL. Dermstore’s auto-replenish price is 93 cents per mL cheaper still ($42.50), but only on the smaller tube.

The supply column uses the retailers’ own estimates, not measurements. If 2 mL lasts 3 months, 3.5 mL lasts 5.25 months: $152.00 ÷ 5.25 = $28.95 a month. That is 62 cents more than auto-replenish ($28.33) and $4.38 less than a one-time 2 mL order ($33.33).

On 2026-10-26, SkinElite showed its tube sold out. Dermstore’s page also sells a “6 Month Supply” at $152.00 ($25.33 a month by its label) and a “6 Weeks Supply” at $59.00 ($39.33 a month), sizes not given in mL. It also marks the conditioner “HSA | FSA eligible,” so you can pay from a health savings account (HSA) or flexible spending account (FSA).

Amazon ties that 6-week option for the lowest upfront price, $59.00, and costs the most per mL. Its listing shows $1,966.67 per fluid ounce (fl oz), which implies a 0.03 fl oz box, rounded. The true size could be about 0.74 to 1.03 mL, or about $57–$80 per mL.

Apply One Thin Line at the Upper Lash Base, Once a Day

The directions on SkinElite’s page are short. Apply it once a day as a thin line along the base of the upper lashes “only.” One dip of the applicator covers both eyes. The label gives its own reason for keeping the line thin: “dripping into the eye may cause irritation.”

Then wait. SkinElite’s page says to “let dry completely (2-3 minutes)” before you put on other beauty products or go to sleep.

Oil-Based Removers Can Leave a Film That Blocks the Conditioner

If you take off eye makeup with an oil-based remover, make sure none of it is left before the conditioner goes on. Dermstore’s product page warns that oil-based makeup removers and cleansers “can leave behind a film.” That film may sit between your lashes and the conditioner.

In other words, part of each day’s stroke could land on oil instead of lash. The order is makeup off, oily film gone, then conditioner.

Five Groups the Label Rules Out, Plus Dry Eyes and Styes

Read the caution on SkinElite’s page before you pay. It says not to use the conditioner:

• on damaged or irritated skin
• if you are pregnant
• if you are nursing
• while undergoing treatment for glaucoma
• while undergoing treatment for cancer

The same text adds: “Not recommended if you have dry eyes, eye infections, styes or any other eye-related disorder.” It also says: “Do not get in eye. Rinse immediately.” If any of these fits you, skip it and ask an eye doctor before trying any lash serum.

The Retail Pages Show Key Ingredients, Not the Full List

You can’t read the full ingredient list on these retail pages. Dermstore and Amber Spa list key ingredients only: peptides, biotin, lipids, green tea, panthenol, ginseng, swertia and saw palmetto. SkinElite says: “Please email for complete ingredients list.”

That gap matters if you want to know whether it contains a prostaglandin analogue (a lab-made version of a hormone-like compound). These pages don’t confirm one and don’t rule one out. Read the full list on the box, or email SkinElite before you buy, as its page suggests. The FDA says eye cosmetics sold at retail “are required to have an ingredient declaration on the label.”

A 6-Step Daily Checklist: Prep, Apply, Dry, Stop Signs

The sections above cover each step. This list puts them in order and adds when to stop.

1. Before you open it: check the caution list on SkinElite’s page. If one line fits you, stop here.
2. Prep: take off eye makeup and leave no oil-based remover film, per Dermstore’s warning.
3. Apply: one dip, one thin line, upper lashes only.
4. If it gets in your eye: rinse with water right away.
5. Dry: 2-3 minutes before makeup or sleep.
6. Stop signs: if redness or irritation starts, stop using it at once. See a doctor if symptoms persist, as the label directs. The FDA notes that the eyelids are delicate and that an allergic reaction, irritation or other injury there “can be particularly troublesome.”

Verdict: The 3.5 mL Tube for One-Time Buyers, Auto-Replenish for Subscribers

• Verdict: a once-a-day lash conditioner for people with healthy eyes who can keep oil-based removers off their lashes. One-time buyers should get the 3.5 mL tube: $28.95 a month if it lasts as long per mL as the 2 mL tube. Subscribers pay less with Dermstore’s 2 mL auto-replenish, at $28.33 a month.
• The flaw, and its fix: the retail pages don’t show the full ingredient list, so you can’t check every ingredient online. Fix: email SkinElite for the list before you buy, as its page asks, or read the box before first use. A one-time 2 mL order also costs $50.00 per mL. Subscribe or buy the bigger tube to pay less.
• Strengths: one application a day. SkinElite lists it as “oil-free and safe for use with eyelash extensions,” and Dermstore and Amber Spa name peptides, biotin and panthenol among its key ingredients. In Amber Spa’s 63-person survey, 98% reported improved lash appearance.
• Who should skip it: anyone in the label’s five groups, and anyone with dry eyes, eye infections, styes or another eye disorder. Ask an eye doctor instead. If you want a small first purchase, Amazon’s $59 listing costs the least upfront but the most per mL.

FAQ

Which RevitaLash Advanced Size Costs the Least?

Per mL, Dermstore’s auto-replenish 2 mL is lowest at $42.50, then SkinElite’s 3.5 mL at $43.43. One-time 2 mL orders cost $50.00, and Amazon works out to about $57–$80 (all prices from 2026-10-26). Per month at the same rate of use, auto-replenish ($28.33) edges out the 3.5 mL tube ($28.95); by SkinElite’s “6 month supply” label, the tube is $25.33.

Does the 3.5 mL Tube Really Last Twice as Long?

The retailers say so, but the volumes don’t quite match. The 3.5 mL tube holds 1.75 times as much (3.5 ÷ 2) yet is listed as lasting twice as many months. At the 2 mL tube’s rate, it lasts 5.25 months. Treat the per-month figures as retailer estimates.

Can I Order It to California?

Not from Amber Spa. Its page says the product “cannot be shipped to California.” Check the shipping terms of the other retailers in the table at checkout.
