As a beauty industry professional with years of experience evaluating cosmetic products, I’ve thoroughly analyzed customer feedback on MAC’s Stack Superstack Micro Brush Mascara to provide you with an in-depth assessment of this popular product. This review encompasses performance analysis, application insights, longevity evaluation, and value considerations to help you determine if this mascara deserves a place in your beauty arsenal.
Product Overview
MAC Stack Superstack Micro Brush Mascara has generated significant buzz in the beauty community, particularly for its “stackable” formula that promises buildable length and volume without clumping. The product features a micro brush design (though some customers noted receiving a mega brush variant) intended to capture and coat even the smallest lashes. Priced in the premium category (approximately $23-28 at authorized retailers), this mascara positions itself as a high-end alternative to drugstore options.
Performance Analysis
Length and Volume Enhancement
The most frequently praised aspect of this mascara is its ability to dramatically lengthen lashes. Multiple users reported that the product delivered such impressive length that it eliminated their need for false lashes: “Forget false eyelashes! This mascara really lifts and separates your lashes!” Another enthused customer shared, “The best I ever used, I love it, when I wear it I get a lot of compliments, they think I’m wearing lashes.
The “stackable” formula appears to deliver on its promise for many users, allowing for multiple coats without developing the dreaded clumpy appearance that plagues many mascaras. One user noted, “You can do so many layers without it getting clumpy, I’ve tried many mascaras but this is my favorite by far.” This buildable quality makes it versatile for both subtle daytime looks and more dramatic evening applications.
However, performance consistency appears to be an issue. While many users experienced exceptional results, others found the mascara underwhelming: “You need to add several layers to achieve the look desired” and “I feel like I had to work too hard to get the layer of mascara I wanted on my eyelashes.” Some users even reported virtually no enhancement effect: “Did not extend my lashes at all.”
Application Experience
The application experience varies significantly among users. Those who had positive experiences highlighted the smooth, clump-free application: “Goes on smoothly with no clumps” and “Easy to wear, doesn’t get all dry and clumpy on your eyes.” The micro brush design received specific praise from those who appreciated its ability to reach smaller lashes: “I do like that it seems to get all the tiny lashes.”
Conversely, several customers reported significant application issues. Some found the product too dry immediately upon opening: “Just received this…opened it….and it was already dried out” and “It seemed like there was barely any mascara on the brush and I had to go over my eyelashes several times (too many times) to get the desired effect.” Others experienced the opposite problem, finding the formula excessively wet and prone to messiness: “Clumpy, sticky mess.
The brush size preference appears to be subjective, with some users specifically seeking out the micro brush variant while others received (and sometimes preferred) the mega brush option. One dissatisfied customer noted: “I love this mascara with the micro brush from previous use but unfortunately I was sent the mascara with the wrong brush. I was sent a mega brush.”
Longevity and Wear Performance
Staying Power
Longevity feedback presents perhaps the most dramatic dichotomy in user experiences. Many satisfied customers praised the mascara’s all-day wear: “It wears well all day and looks great on!” and “Long lasting and not clumpy!” These users found that the product maintained its appearance throughout their day without requiring touch-ups.
However, an almost equal number of customers reported significant issues with the mascara’s staying power: “This mascara lasts about an hour and then starts to flake” and “You have to carry with you so you can reapply later in the day.” These contrasting experiences suggest potential formula inconsistency or significant variation in how the product interacts with different skin types and environments.
Smudging and Flaking
Smudging emerged as the most common complaint among dissatisfied users. Numerous reviews mentioned issues with the mascara transferring to the under-eye area: “It leaves big black circles under your eyes” and “If you touch your eyes at all smudges so disappointing!” Even some otherwise satisfied customers noted this limitation: “Great mascara but it does run a bit on my lower lashes leaving smudges after a few hours of wear.
Several users specifically mentioned that the non-waterproof formula was particularly prone to smudging in humid conditions or when exposed to moisture: “Even in light rain it [runs] and “If you get hot it smudges.” A few users suggested that the waterproof version might resolve these issues, though the waterproof variant itself received mixed reviews, with one user calling it “The worst waterproof mascara ever.
Flaking was mentioned less frequently than smudging but still appeared in multiple negative reviews: “This mascara lasts about an hour and then starts to flake.”
Removal Experience
Removal experiences varied widely. Some users appreciated the mascara’s easy removal: “Easy to remove with eye makeup remover” and “The best mascara doesn’t leave lumps of black, stays for a long time and is easy to clean, just what a woman needs in life!” However, others found removal challenging: “Looks great on but doesn’t come off easily!”
This variation might reflect differences in the removal products used, individual skin sensitivity, or potentially inconsistent product formulation across batches.
Value Assessment
Price-to-Performance Ratio
At approximately $23-28 per tube from authorized retailers, this mascara falls squarely in the premium category. Value assessments varied dramatically among users. Those who experienced exceptional results generally felt the product justified its price: “Worth the money!” and “This is a bit on the pricey side, but definitely delivers for the money… Definitely would purchase again.”
Conversely, users who experienced performance issues found the price difficult to justify: “It is over priced for the amount of product you use when you apply” and “Not worth the price. I have bought better at less than half that price.” Several users explicitly stated that the product’s performance didn’t match its premium positioning: “This mascara is horrible especially for the money.”
Some customers expressed concern about potential price inflation from unauthorized sellers, with one noting: “This item is almost $50. I went to Ulta and paid $28 plus tax. It does work wonderfully, I’m just curious about the up charge.”
Product Quality and Consistency
A concerning number of reviews mentioned receiving products that appeared to be dried out, previously used, or improperly packaged: “Product arrived with the packaging open and looking worn out” and “The item did not come in the retail box or sealed. It was just in a plastic bag.” These experiences raise questions about supply chain integrity and quality control, particularly for products purchased through online marketplaces rather than directly from MAC or authorized retailers.
Several users who otherwise liked the product expressed disappointment with premature drying: “Worked well but haven’t had it for long and it’s already dried out.” This issue directly impacts the product’s value proposition, as customers effectively receive less usable product than expected.
Comparison to Alternatives
While many users found this mascara superior to alternatives (“This has got to be the best mascara in the market”), others explicitly stated that drugstore options outperformed it (“Plenty of drug store mascaras are far better than this one unfortunately”). This suggests that while the product may indeed offer exceptional performance for some users, its superiority is not universal.
Several long-term users expressed strong brand loyalty: “I found this mascara a few years ago. It is the only mascara I buy now. It never disappoints!” This indicates that for certain customers, the product delivers consistent results that justify continued repurchase despite the premium price point.
Who Should Consider This Mascara
Based on the pattern of feedback, this mascara appears best suited for:
-
- Users seeking dramatic length: Those whose primary concern is lengthening rather than volumizing will likely appreciate this formula.
- Individuals with short lashes: Several users with self-described short lashes reported exceptional results: “My lashes are pretty short and this mascara gives them a lot of length without looking chunky.
- Those who prefer buildable formulas: Users who enjoy applying multiple coats to achieve their desired look will appreciate the “stackable” quality.
- People with normal to dry skin types: The smudging issues reported suggest that those with oilier skin or who live in humid environments might experience more transfer problems.
Who Should Consider Alternatives
This mascara might not be ideal for:
- Those seeking immediate volume: Users seeking dramatic volume without building multiple layers might find this formula lacking.
- Individuals with oily skin or who live in humid environments: The frequent mentions of smudging suggest this formula may not hold up well in these conditions unless you opt for the waterproof version.
- Budget-conscious consumers: Given the mixed performance reviews, those with budget constraints might achieve similar or better results with less expensive alternatives.
- Users who prioritize convenience: The need for layering reported by many users makes this a less convenient option for those who prefer a one-coat-and-go approach.
Authentic Product Concerns
A significant pattern emerged regarding packaging and product authenticity. Multiple users reported receiving the product in plastic bags rather than official MAC packaging: “It came in a small ziplock baggie. That is super iffy” and “The mascara was in a plastic bag and not in the original box.” These experiences suggest potential gray market distribution issues.
When purchasing this or any premium cosmetic product, consumers should prioritize authorized retailers (MAC stores, department store MAC counters, Ulta, Sephora, or the official MAC website) to ensure they receive authentic, properly handled merchandise.
Final Verdict
MAC Stack Superstack Micro Brush Mascara presents a study in contrasts. When it performs well, it appears to deliver truly exceptional results, creating length and definition that rivals the appearance of false lashes. However, the significant variation in user experiences suggests potential inconsistencies in formulation, packaging, or distribution.
For those who experience the product at its best, the premium price point seems justified. However, the high incidence of performance issues, including smudging, flaking, and premature drying, makes this a somewhat risky investment, particularly when purchased through non-authorized channels.
Rating: 3.5/5 Stars
Strengths: Exceptional lengthening capability, buildable formula, ability to reach small lashes with the micro brush, potential to eliminate the need for false lashes.
Weaknesses: Inconsistent performance across users, smudging issues, premium price point, concerns about product authenticity in some distribution channels.
For those intrigued by this mascara but concerned about the mixed reviews, I recommend:
- Purchase only from authorized retailers to ensure product authenticity
- Consider the waterproof formula if smudging is a concern
- Be prepared to layer the product for maximum impact
- Use an oil-based makeup remover for effective removal
Whether this mascara will become your holy grail or a disappointing experiment largely depends on your lash type, skin chemistry, and specific performance priorities. For those who find the right match with this formula, it may well become an indispensable part of your beauty routine, while others might be better served by continuing their search for the perfect mascara.
