Overglaze Hydrating Lip Gloss for 24-Hour Moisture

ILIA Overglaze Hydrating Lip Gloss for 24-Hour Moisture is a sheer, buildable lip gloss that combines dimensional shine with a plush gel texture and clinically tested hydration. The 0.16 fl oz / 5 mL formula is available in 12 shades and is designed to feel cushiony rather than sticky while resisting visible bleeding and feathering around the lip line. ILIA highlights fenugreek seed extract and sustainably sourced seaweed extract as the primary skincare-focused ingredients.

Unlike an intense tingling lip-plumper, Overglaze approaches the appearance of fuller lips primarily through moisture and surface smoothing. ILIA reports 24-hour hydration and increased measured lip volume in instrumental testing, so the most accurate expectation is hydrated, smoother and visibly fuller-looking lips, not a permanent change in lip shape or size.

About Overglaze Hydrating Lip Gloss for 24-Hour Moisture

Overglaze sits between traditional lip gloss and moisturizing lip care. Its base is rich in emollient and film-forming ingredients that create shine and help reduce moisture loss, while fenugreek seed extract, Undaria pinnatifida seaweed extract and vitamin E add the skincare-focused side of the formula. ILIA describes the finished texture as plush and gel-like, with sheer color that can be worn alone or layered over another lip product.

The formula is dermatologist tested, vegan and made without added fragrance or flavor. ILIA also states that Overglaze is formulated without silicone or gluten.

The absence of SPF is worth noting. A glossy finish does not provide meaningful sun protection by itself, so daytime lip protection still requires a separate SPF lip product when needed. The American Academy of Dermatology recommends an SPF 30 or higher lip balm when outdoors, particularly when lips are dry or chapped.

Overglaze Hydrating Lip Gloss for 24-Hour Moisture Features

Overglaze is designed to solve several common lip-gloss complaints at once. ILIA positions it as long wearing while maintaining a soft gel texture, sheer rather than heavy pigment, and a glossy finish that does not feel conventionally tacky. The company also specifically formulated it to resist color moving beyond the lip line.

The skincare element is more substantial than simply adding one botanical extract to an otherwise basic gloss. The formula’s first several ingredients are emollient and film-forming materials that help create a smooth coating over the lips, while caprylic/capric triglyceride and ethylhexyl palmitate add slip and conditioning.

24-Hour Hydration Claim

ILIA describes Overglaze as clinically proven to hydrate for 24 hours. Ulta’s current product information identifies the hydration and lip-volume findings as instrumental testing involving 22 people.

That wording is important. It means the 24-hour result is tied to product testing rather than being inferred merely from the presence of oils or botanical extracts.

It does not mean the glossy layer itself necessarily remains visibly untouched on the lips for a full day. Eating, drinking, wiping the mouth and ordinary wear can remove surface gloss even while a moisturizing effect remains measurable.

For Erothots, the product is therefore better described as offering 24-hour hydration support rather than “24-hour perfect gloss wear.”

Fenugreek Seed Extract

Trigonella Foenum-Graecum Seed Extract, or fenugreek seed extract, is one of ILIA’s two headline skincare ingredients. It appears near the end of the ingredient declaration, alongside tocopherol and seaweed extract.

ILIA associates fenugreek with nourishing, softening and hydration-based plumping. The key qualifier is with hydration. A moisturizing ingredient can make lips look smoother and temporarily fuller as dryness and surface lines become less apparent, but this should not be confused with permanently increasing lip tissue.

The ingredient therefore fits naturally into a gloss intended to create a cushioned, supple appearance rather than an aggressive tingling-plumper effect.

Seaweed Extract And Visible Lip Definition

The formula also contains Undaria Pinnatifida Extract, a brown seaweed ingredient. ILIA states that this ingredient helps visibly improve lip definition and volume.

Again, “visibly” is the useful word. Cosmetic improvement in definition can come from hydration, smoother surface texture and the way a glossy finish reflects light.

Overglaze should not be represented as an alternative to cosmetic procedures or as permanently altering lip anatomy. Its effect remains within the cosmetic categories of moisturization, shine, color and a visibly plumper appearance.

Tocopherol For Conditioning Support

Tocopherol, or vitamin E, is included in the formula alongside the botanical extracts.

In lip products, vitamin E is commonly used as an antioxidant and conditioning ingredient. Within Overglaze, it supports the emollient formula rather than functioning as a separate medical treatment for cracked lips.

Very dry or persistently cracked lips may need simpler barrier-focused care. The American Academy of Dermatology’s chapped-lip guidance recommends non-irritating lip moisturizers and notes that thicker ointments such as petroleum jelly can be particularly useful when lips are severely dry.

Overglaze is therefore best considered hydrating makeup rather than a replacement for treatment of persistently damaged lips.

A Gloss Base Built For Cushion And Shine

The first ingredients include hydrogenated polydecene, polybutene and hydrogenated styrene/isoprene copolymer. These ingredients are central to the texture and shine of the gloss.

Hydrogenated polydecene provides a smooth emollient feel. Polybutene is commonly used to create gloss, adhesion and a cushiony texture. The styrene/isoprene copolymer contributes film-forming structure so the gloss can remain cohesive instead of behaving like a thin oil.

Caprylic/capric triglyceride, ethylhexyl palmitate and the complex dimer-dilinoleate emollient add further slip and comfort.

This explains why Overglaze can feel richer than a lip oil while remaining softer than the especially tacky gloss formulas traditionally associated with very long wear.

Non-Sticky Gel Texture

ILIA explicitly describes Overglaze as non-sticky and says the formula has a plush, cushiony gel texture.

“Non-sticky” remains partly sensory because people have different tolerance for the film created by lip gloss. Overglaze still contains ingredients designed to adhere to the lips, so it should not be expected to feel identical to bare skin or a lightweight water-based treatment.

Its intended difference is that the gloss provides substantial shine without the heavy tack associated with some traditional high-shine formulas.

Sheer, Buildable Color

Overglaze is not an opaque liquid lipstick. ILIA describes all 12 shades as sheer and buildable, meaning the natural lip color remains part of the finished look.

One swipe creates a softer wash of color. Additional passes can increase the visible tint and gloss, although even layered application is designed to remain more translucent than full-coverage lipstick.

This makes the range particularly flexible for layering because the gloss can modify another lip color without completely covering it.

The 12 Overglaze Shades

ILIA currently offers twelve ceramic-inspired shades: Porcelain, a pale pink pearl; Crystalline, beige pink; Enamel, mauve pink; Vessel, warm berry pearl; Slip, rose pink; Mosaic, cool lavender pearl; Figure, berry mauve; Resin, rich burgundy; Clay, warm brown; Terra, terracotta; Flambé, vivid red; and Studio, raspberry red.

The range mixes non-pearl and pearl finishes rather than making every shade look identical apart from color. Porcelain, Vessel and Mosaic have specifically described pearly effects, while shades such as Clay, Terra and Resin provide deeper color directions.

Because the formula is sheer, the same shade can appear somewhat different depending on natural lip pigmentation and whether another color is worn underneath.

Porcelain, Crystalline And Enamel

The lighter end of the collection begins with Porcelain, a pale pink pearl that adds a light-reflective finish without substantial depth. Crystalline is a beige pink, while Enamel moves toward mauve pink.

These shades are useful when the goal is to add shine and a subtle tint rather than dramatically change the natural lip color.

Because Overglaze is translucent, deeper natural lip pigmentation can influence how much of these lighter tones remains visible.

Berry And Mauve Shades

Vessel is described as a warm berry pearl, Figure as berry mauve and Resin as rich burgundy. Mosaic adds a cooler lavender-pearl option.

These shades provide more tonal depth while retaining the sheer character of the formula. Resin is the deepest direction in the current range, making it useful when a darker glossy effect is wanted without moving to full opacity.

Warm Browns And Reds

Clay provides warm brown, while Terra is terracotta. The brighter end includes Flambé, a vivid red, and Studio, a raspberry red.

The sheer base means these colors can be worn lightly or built over lip liner for more definition.

Long Wear Without Being Transfer-Proof

ILIA describes Overglaze as long wearing, but it does not position the product as an immovable transfer-proof liquid lipstick.

That distinction keeps expectations realistic. Gloss contains emollient materials intended to remain comfortable and shiny, so some transfer during eating or drinking is normal.

The stronger wear claim concerns the formula’s ability to stay smooth and resist undesirable movement into surrounding lip lines rather than becoming completely transfer-free.

Resisting Bleeding And Feathering

ILIA reports a clinical study involving 52 people in which 100% said the gloss did not bleed or feather after application.

Bleeding refers to lip color migrating beyond the intended lip boundary, while feathering describes smaller lines of product spreading into fine lines around the mouth.

A cohesive gel texture and film-forming base can help control this movement.

The result remains a study finding, not a guarantee under every situation. Heavy layering, oily food, repeated rubbing and pairing with other products can alter wear.

Bare-Lip Appearance After Continued Use

Ulta’s current product page also reports that 98% of participants said bare lips looked and felt healthier, with the cited testing information referencing a 52-person clinical study and results tracked through 21 days.

This is best presented as participant-reported perception rather than proof that the product medically repairs lip tissue.

Hydration can make dry lips look smoother and more comfortable, which can reasonably contribute to the perception of healthier-looking bare lips.

Added Fragrance And Flavor Are Left Out

ILIA states that Overglaze contains no added fragrance or flavor.

That is particularly relevant for a lip product because fragrance and flavoring materials sit directly around the mouth and are frequently reapplied.

The American Academy of Dermatology notes that fragrance can be problematic for some people with dry or irritated lips and recommends fragrance-free products when chapping is present.

Fragrance-free does not guarantee zero chance of irritation. The FDA’s cosmetic allergen guidance explains that reactions can occur to many different cosmetic ingredients depending on individual sensitivity.

Vegan And Silicone-Free Positioning

ILIA identifies Overglaze as vegan and states that the formula was developed without silicone.

The silicone-free point should be treated as a formulation preference rather than evidence that silicones in cosmetics are inherently undesirable.

Overglaze achieves its slip and high-shine texture using alternative emollients and polymers such as hydrogenated polydecene, polybutene and dimer-dilinoleate derivatives.

Application And Layering

The doe-foot applicator can be swept directly across bare lips for sheer color and shine. ILIA also recommends layering Overglaze over its Lip Sketch Hydrating Crayon when additional definition or a stronger color base is desired.

For a softer result, one even layer is enough. Building a second layer intensifies the gloss and tint without turning the formula fully opaque.

If a lip liner is being used, defining the lip line first and applying gloss afterward generally gives more control than trying to create precise edges with the gloss alone.

Using Overglaze On Dry Lips

A hydrating gloss can make ordinary dryness feel more comfortable, but very flaky lips may show texture underneath a shiny product.

The AAD recommends avoiding picking or biting peeling lips because this can slow recovery and increase irritation. Its lip-care recommendations also advise stopping products that cause burning, stinging or discomfort.

Overglaze can be worn once the lips feel comfortable, but severe cracking or persistent irritation deserves a simpler moisture-focused routine rather than repeatedly covering the area with makeup.

Lip Gloss Does Not Replace SPF

Overglaze provides shine, tint and hydration, but ILIA does not list an SPF for this product.

When lips will be exposed to sunlight, dermatologists recommend using a lip balm with SPF 30 or higher.

A separate SPF lip product can be used according to its own directions. The glossy appearance of Overglaze should not be interpreted as UV protection.

Lip Color Pigments Vary By Shade

The base formula stays similar across the collection, while color additives differ according to shade. Ulta lists possible pigments including titanium dioxide, iron oxides, Red 6 and Red 7 Lake. The official ILIA ingredient listing for the selected shade also includes reflective materials such as calcium sodium borosilicate, synthetic fluorphlogopite and tin oxide where applicable.

The FDA regulates color additives used in cosmetics, including pigments intended for lip products. A color approved for one cosmetic use is not automatically approved for every area of the body.

For someone checking a particular pigment sensitivity, the ingredient declaration for the chosen shade should remain the final reference.

Overglaze Hydrating Lip Gloss Ingredients

Ulta currently lists the shared formula as:

Hydrogenated Polydecene, Polybutene, Hydrogenated Styrene/Isoprene Copolymer, Caprylic/Capric Triglyceride, Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate, Bis-Behenyl/Isostearyl/Phytosteryl Dimer Dilinoleyl Dimer Dilinoleate, Ethylhexyl Palmitate, Tocopherol, Trigonella Foenum-Graecum Seed Extract and Undaria Pinnatifida Extract. Depending on shade, the product may also contain Titanium Dioxide, Iron Oxides, Red 6 and Red 7 Lake.

ILIA’s own selected-shade ingredient listing may additionally show pearl-effect materials such as calcium sodium borosilicate, synthetic fluorphlogopite and tin oxide.

Because pigments vary among the twelve shades and formulas can be updated, the box or tube received should be the final ingredient reference for a specific purchase.

Who May Appreciate Overglaze Hydrating Lip Gloss

Overglaze makes the strongest case for someone who wants visible gloss and sheer color without giving up a moisturizing lip feel. Its cushiony texture, 24-hour hydration testing and anti-feathering design distinguish it from a simple decorative gloss.

It may also appeal to people who prefer fragrance-free and flavor-free lip makeup or who like the flexibility of wearing gloss alone and over lip liner or lipstick.

Someone looking for completely opaque pigmentation may prefer a lipstick or full-coverage liquid formula. Someone whose main concern is severely cracked lips may be better served initially by a simple protective balm or ointment until the irritation settles.

What Makes Overglaze Hydrating Lip Gloss for 24-Hour Moisture Different

The defining quality of ILIA Overglaze Hydrating Lip Gloss for 24-Hour Moisture is the balance between makeup performance and sustained moisture. Its 5 mL gel formula creates dimensional shine and sheer buildable color while fenugreek seed extract, seaweed extract, vitamin E and an emollient-rich base support softness and hydration. ILIA’s instrumental testing reports 24-hour hydration and increased visible volume, while a separate 52-person study found that all participants said the gloss resisted bleeding and feathering after application.

The range also gives shoppers twelve distinct color directions, from pale Porcelain and beige-pink Crystalline through berry, brown, terracotta and vivid red shades, without changing the sheer character that defines Overglaze.

For Erothots, Overglaze Hydrating Lip Gloss for 24-Hour Moisture is best positioned as a 5 mL skincare-minded sheer lip gloss with twelve buildable shades, clinically tested 24-hour hydration, non-sticky dimensional shine and moisture-based visible plumping, while keeping the distinction clear between cosmetic fullness and any permanent change to lip structure.
