Before You Lift: What to Know About Lash Lift Kits, Safety & Ingredients in 2025

Lash lifts and tints? Still dominating beauty menus in 2025, and it’s easy to see why. Clients love the natural, low-maintenance results. Lash artists rely on the service to build loyalty, boost retention, and fill their calendars.

But lately, we’ve been hearing more pros (and clients!) ask the real questions:

• Are lash lifts still safe with today’s formulas?

• Are these kits actually compliant with the new ingredient rules?

• And how can you be sure what’s in your bottles is actually client-safe?

With new ingredient updates affecting lash and brow perming products, these questions are more than just buzz, they’re essential. So let’s break down exactly what you need to know to protect your business, deliver safe results, and feel good about what’s sitting on your shelf.

Are Lash Lifts and Tints Safe in 2025?

Yes, when the products are well-formulated and used with precision.

As a lash pro, you already know the basics: a perming solution softens the disulfide bonds in the lash hair, reshaping the curl. A setting solution locks in the lift. Add a tint? Instant wow factor.

But safety doesn’t stop at technique. In 2025, it’s all about what’s inside your lift kit.

What makes a lift safe comes down to three things:

• The formula itself: Is it using compliant, eye-area-safe ingredients?

• Your technique: Timing, isolation, and lash health matter more than ever.

• The client’s lash condition: Damaged or brittle lashes can’t tolerate what healthy ones can.

The treatment isn’t the issue, it’s what’s in your solution that counts. And that’s where the real shift is happening.

Are Lash Lifts Still Worth It?

From both a results and revenue standpoint? Absolutely.

Lash lifts continue to be one of the most profitable, low-maintenance services you can offer. They deliver immediate results that last up to 6–8 weeks, all with minimal product usage. For clients, that means no daily curling or mascara. For artists, it means high ROI with fewer complaints about irritation, if the system is well-formulated.

So yes, lash lifts are still worth it. But only if the chemistry is current.

What to Look for in a Lash Lift Kit (Especially This Year)

Not all kits are created equal, and in 2025, the focus has shifted from just performance to performance + compliance. Here's what separates a trusted lash lift system from one that’s stuck in the past:

1. Ingredients That Meet Today’s Standards

This is where things get specific, and where many pros get caught off guard.

Let’s talk Thioglycolic Acid (TGA): it’s still approved for use in lash and brow perms in Canada, as long as it’s pure and used within regulated concentrations.

But its esters, especially Glyceryl Thioglycolate (GTG)? Not so lucky. GTG is now officially restricted due to higher risks of irritation and sensitization, and can no longer be used in products near the eye area.

Knowing the difference between TGA and its esters is non-negotiable in 2025. If your kit contains GTG, it’s not compliant.

2. Smart Packaging & Sanitary Protocols

Safe ingredients need safe delivery systems, so look for packaging that minimizes contamination and preserves formula integrity, like:

• Airless pumps

• Single-use sachets

• Sealed tubes with minimal oxygen exposure

These aren’t just nice-to-haves, they help avoid cross-contamination and keep active ingredients fresh.

3. Transparency from the Brand

The ingredient list shouldn’t feel like a mystery novel. The brand behind your kit should:

• Clearly label every ingredient

• Explain what each one does (and what’s been removed)

• Keep you updated when regulations change

At Curacoro, this is non-negotiable. Every product we sell comes with the full breakdown, no mysteries, no guesswork.

Ingredient Cheat Sheet: TGA, Esters & Cystamine

Let’s get specific, because this is where things have changed.

✅ Thioglycolic Acid (TGA)

Thioglycolic Acid (TGA) is a proven active ingredient widely used in professional lash and brow perming systems. It works by softening and reshaping the disulfide bonds in hair, allowing for effective lifting and curling. When used properly, TGA is still approved by Health Canada and is a key component in our Lash Lift Pro Kit.

❌ TGA Esters (like Glyceryl Thioglycolate)

In contrast, TGA esters such as Glyceryl Thioglycolate are byproducts of TGA that were commonly found in older perm systems. These compounds are more likely to cause irritation and sensitization, and due to these risks, they have now been officially banned in Canada for use in lash and brow services. Despite this, some legacy kits still include TGA esters, so it's important to always check your product's INCI list.

✅ Cystamine

Cystamine is a newer and gentler alternative to traditional lifting actives like TGA. It reshapes lashes with significantly less risk of over-processing or irritation, making it an excellent choice for sensitive clients or those trying a lash lift for the first time. This innovative ingredient is featured in our 2in1 Lash Lift Kit.

What Health Canada’s 2025 Update Means for You

This year, Health Canada cracked down on outdated lash and brow ingredients. The takeaway?

• GTG is banned.

• Pure TGA is still allowed, if used correctly.

• Cystamine is in the clear and a smart choice for more sensitive services.

You don’t need to throw out every TGA-based kit, just the ones that rely on esters. Review every ingredient list and stick with brands that clearly show what’s compliant.

With Curacoro’s Lash Lift Pro Kit (TGA) and 2in1 Kit (Cystamine), you're covered. Both are fully compliant and formulated for safe, professional use in 2025 and beyond.

The Takeaway

Lash lifts still deserve a prime spot in your treatment menu, as long as your kit is up to today’s standards. And in 2025:

• Lash lifts are still safe

• Lash lifts are still worth it

• But the ingredients inside your kit matter more than ever

So if it’s been a while since you audited your shelf, now’s the time.
