NYX PROFESSIONAL MAKEUP Lip IV Hydrating Gloss Serum, Lip Stain

✅ What it is

• The product is described on the NYX UK site as Lip IV Hydrating Gloss Stain, a “vitamin-infused gloss serum with water-breaking technology” that gives wet-shine colour with a lasting lip-staining effect. 

• Key formula claims: up to 12 hours hydration, with ingredients like magnesium, vitamin B12 and coconut water.

• The formula is marketed as hybrid: “2-in-1 Wet Shine & Lip Gloss Stain.” 

• Available in multiple shades (16+ as per listing) and in a gloss format that leaves a stain behind as the gloss wears off.

🎯 Key Features & Benefits

From the official descriptions and user feedback:

• Long-lasting hydration: Up to 12 hours claimed. 

• Gloss + stain hybrid: Initially gives a glossy wet finish, and gradually leaves behind a tint (stain) as the gloss fades.

• Hydrating ingredients: Infused with things like magnesium (to help barrier/hydration), vitamin B12 (supports lips) and coconut water (electrolytes) for a more comfortable wear. 

• Multiple wear-modes: You can wear it as a full glossy colour, or let it set and then blot off the top layer to leave more subtle stain. Some users prefer the stain effect.

• Good shade variety: From nude-browns (e.g., “Hydra Honey”, “Caramel Drip”) to more vivid tones. This makes it suitable for different skin tones and styles.

🧴 How to Use

• Prep lips: If desired, exfoliate and moisturise lightly (especially if your lips are dry) for smooth application.

• Apply: Use the doe-foot applicator to swipe the product across the lips (centre, then corners).

• Wear styles:

  • Gloss look: Just wear it and enjoy the shiny, fresh finish.

  • Stain effect: After application, let it sit for a bit (a few minutes) then blot or remove the top gloss layer—you're left with the tint/stain underneath. Many users mention this method.

• Reapply as needed: Because it’s a gloss + stain hybrid, you might want to refresh if you eat/drink a lot, though the tint may remain.

• For best results: keep a liner handy if you have fine lip lines, use a lip balm underneath if lips are dry, and pick a shade you like both for the gloss look and the stain look.

⚠️ Things to Consider / Possible Drawbacks

• Glossiness & transfer: Because part of the effect is a gloss finish, you might get some transfer or need to reapply if eating/drinking. One review:

  “The gloss formula transfers (like any gloss would) … I preferred wiping it away after 10 minutes to sport just the low-maintenance stain.”

• Shade reality may differ: Users report that the stain left behind or the final colour can differ from initial tube colour or online swatches. For example:

  “I got hydra honey and it looks more of a warm brown colour. Not pink at all!”

• Texture/consistency issues: A few users noted concerns:

  “It melts and separates … the colour did not match the photos … the gloss looked fine but the stain is weak.” 
  Some reported a coconut scent (which may be strong for some) and even concerns about mild irritation/allergy: “My reaction … I honestly thought I had purchased a lip plumper without realising it!”

• Label/packaging confusion: Some markets list it as “Gloss Stain”, others as “Gloss Serum”. This may create confusion about the exact format. 

• Not ultra-matte: If you prefer totally matte finishes without any gloss shine, this product might feel glossier than you like.

🤔 My Verdict: Is It a Good Fit for You?

Yes — I would recommend this product if you:

• Want a hybrid lip product that gives both a glossy finish and a lasting stain effect.

• Prefer something comfortable, hydrating on lips (rather than drying matte).

• Are interested in nude-brown or medium shades that work well for everyday looks but also have staying power.

• Don’t mind some gloss/shine and occasional transfer because you like the look and feel.

You might look elsewhere if you:

• Prefer a totally matte finish or zero transfer.

• Have very dry, cracked lips that require a heavy balm first. While this product is hydrating, the stain left after the gloss may emphasise texture if your lips are very dry.

• Want a super long-wear stain that lasts untouched through heavy eating/drinking – some users report good stain effect, but not always “indestructible”.

• Are allergic to coconut extract or strong scents (since it has coconut water + scent reported).
