The LA indie brand that donates to women’s shelters made a lip oil that keeps showing up in IPSY bags and TikTok hauls. Here’s what’s actually inside the bottle.
If your lip balm leaves your lips feeling coated but not actually moisturized, or your gloss turns into a hair magnet the second wind hits, you’re not alone. That specific frustration is exactly where lip oils have carved out a serious audience, and the Moonslice Beauty Lip Oil has become one of the more talked-about options at the budget end of that category.
At $15 for 4.5ml, it sits well below the luxury lip oil tier. But price alone doesn’t tell the story. What makes it worth examining is the formula, the brand’s ethics, and what over 1,600 verified IPSY reviewers actually said about wearing it.

The Brand Behind It
Moonslice Beauty was founded in Los Angeles in 2019 by a women-led team with a specific mission: keep prices accessible and give back. A portion of every sale goes directly to shelters for women, including survivors of domestic violence and minority women. That charitable component is baked into the brand’s identity, not tacked on as an afterthought.
The brand describes its aesthetic as “quintessential LA cool girl,” and the product lineup reflects that: no overwrought packaging, no inflated price tags, just clean formulas that do what they say. The lip oil has become their most visible product, regularly appearing in IPSY Glam Bags and circulating on TikTok beauty hauls.

What the Moonslice Beauty Lip Oil Actually Is
This is a hybrid product. It functions as three things at once: a hydrating lip treatment, a sheer tinted lip color, and a non-sticky gloss. That combination is where it earns its following.
The formula skips alcohol entirely, relying on emollients and antioxidants instead. That means no drying effect, which is a genuine differentiator when most glosses quietly dehydrate lips over time through alcohol-based preservatives.
“You can wear your hair down. The zero stickiness claim holds up.”
The texture lands between thin and slick versus heavy and gloopy. Users consistently describe it as “cushiony,” and the shine it delivers reads as glass-like without the tacky feel that usually comes with that level of gloss.
What’s Inside the Bottle
Key Ingredients
Shea Butter
Deep emollient. Locks in moisture and creates a protective barrier against moisture loss. Responsible for the cushiony body of the formula.
Vitamin E (Tocopheryl Acetate)
Antioxidant that nourishes the lip skin and protects against environmental stress. Supports the treatment function.
Jojoba Oil
Lightweight oil that closely mimics the skin’s natural lipid structure. Hydrates without heaviness or clogging.
Sunflower Seed Oil
Fast-absorbing emollient that delivers slip and smoothness to the formula. Supports overall texture.
Caprylic/Capric Triglyceride
Derived from coconut. A lightweight skin-conditioning agent that keeps the formula feeling clean and non-greasy.
Hydrogenated Polyisobutene
Provides the glossy, film-forming finish while remaining transfer-resistant and non-sticky.
The full ingredient list is alcohol-free. Colorants used include standard FDA-approved pigments such as Red 27 Lake and Titanium Dioxide, which is standard for tinted lip products in this category. INCIdecoder’s breakdown confirms the formula is dominated by emollients, which explains the immediate comfort on dry or chapped lips.
How It Performs: Real User Feedback
With over 1,650 reviews on IPSY averaging 4.2 out of 5 stars, the feedback landscape is broad enough to draw real conclusions from.
What Works
- Glossy without stickiness (confirmed across majority of reviews)
- Immediate smoothing on dry or chapped lips
- High shine finish that photographs well
- Subtle, pleasant fragrance noted positively
- Layerable over other lip colors
- Non-greasy feel throughout wear
Where It Falls Short
- Wear time varies, fades faster after eating or talking
- Some users noted packaging that can leak
- Hydration is immediate but requires reapplication every 2 to 3 hours for some
- Tint is sheer, not buildable for those wanting coverage
The pattern across Reddit threads and verified subscription box reviews points to a product that delivers on feel and finish but asks for more frequent touch-ups than a lip balm treatment would. If you’re using it as a gloss overlay rather than a standalone all-day product, longevity becomes less of an issue.

Who Should Consider the Moonslice Beauty Lip Oil
This product has a fairly wide audience, but it’s most relevant for:
Best Suited For
- Anyone looking for a glossy, moisturizing lip oil under $20 that skips the stickiness
- Vegan and cruelty-free beauty shoppers who want verified ethical formulas

Editor Score
4.2
★★★★☆
Based on verified IPSY community ratings (1,650+ reviews). Strong on texture and finish. Slight deductions for longevity variability and packaging reports.
Where to Buy and What to Watch Out For
Because Moonslice Beauty is an indie brand without mass retail distribution, the safest purchase options are the official Moonslice Beauty website and IPSY. Both guarantee fresh product.
Third-party marketplace listings on platforms like eBay and Poshmark exist, but provenance on those isn’t guaranteed. Given the brand’s low profile in traditional retail, it’s worth sticking to authorized sources to avoid old stock or damaged product.
Bottom Line
The Moonslice Beauty Lip Oil is a well-formulated, fairly priced option for glossy, hydrated lips that doesn’t compromise on ethics. It’s not a replacement for a long-wear tinted lip product, but as a daily treatment gloss from a brand that actually gives back, it holds its own against products that cost significantly more.
