COSRX Lip Plump - Refresh AHA BHA Vitamin C Lip Plumper
What is this lip plumper for?
This is a glossy balm built on petrolatum, hydrogenated polyisobutene and shea butter, with vanillyl butyl ether positioned to create the warming tingle associated with a plumped look. Magnesium ascorbyl phosphate, a vitamin C derivative, and betaine salicylate, a BHA, both appear on the list, though this tube's own ingredient list carries no AHA acid despite the AHA in the product name.
Will the warming tingle irritate sensitive lips?
The tingle comes from vanillyl butyl ether rather than an acid exfoliant, and the list carries no added fragrance or denatured alcohol. Anyone who reacts to warming lip products generally should test a small patch first, since the sensation is a designed feature of the formula rather than an incidental side effect.
Does this balm need repeated use to keep working, or does one swipe do it?
The warming, plumped feeling from vanillyl butyl ether fades as the balm wears through the day rather than building with repeated applications, so reapplying is how the effect continues rather than any cumulative process. Expect the tingle each time you apply rather than a lasting structural change to the lips.
Can this go over lipstick or a tinted lip product?
Yes, it is meant to work over color as a glossy topcoat, or on bare lips. The formula runs on petrolatum, shea butter and waxes, none of which are built to react with pigmented lip products, so layering it over color is the intended use.
How can I confirm my tube is the authentic Korean-market formula?
COSRX checks its own units: locate the batch number and expiration date printed on your tube, then enter them on the verification page at cosrx.com rather than taking a listing's word for it. This tube carries barcode 8809598453401.

28 of 29 explained
- Petrolatum occlusive
- Petrolatum is a purified blend of mineral hydrocarbons. It is the most effective occlusive known, cutting water loss from skin by well over ninety percent, and it is inert and does not feed microbes.
- Hydrogenated Polyisobutene emollient
- Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- Phytosteryl/Isostearyl/Cetyl/Stearyl/Behenyl Dimer Dilinoleate emollient
- This is a heavy plant-sterol ester used in balms and cleansing oils. It softens skin, holds pigment and gives a thick, cushioned glide.
- Butyrospermum Parkii (Shea) Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Diisostearyl Malate emollient
- Diisostearyl Malate is a thick, glossy ester used to hold pigment in suspension and give a cushioned shine. It is the standard emollient in lip products.
- Ethylene/Propylene/Styrene Copolymer thickener
- A rubbery hydrocarbon polymer used to thicken oil phases and stop pigments settling. It is common in lip and stick formulas.
- Sorbitan Sesquioleate emulsifier
- Sorbitan Sesquioleate is a water-in-oil emulsifier and pigment disperser. Cleansing oils use it so water can be worked into the oil at the rinse.
- Microcrystalline Wax occlusive
- Microcrystalline Wax is a fine-crystalled petroleum wax. It gives balms and sticks body and flexibility and holds oil from separating out.
- Vanillyl Butyl Ether active
- A warming sensory agent derived from vanillin. It produces a mild tingling warmth on contact, which is the sensation lip products are describing when they say plumping.
- Butylene/Ethylene/Styrene Copolymer thickener
- A rubbery polymer that gels oils and gives a formula cushion and cling. It is usually declared alongside its ethylene/propylene/styrene partner.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
16 more explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate antioxidant
- This is a stabiliser that keeps the oils and fragrance in a formula from oxidising. Its job is the shelf life of the product rather than any effect on skin.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Melia Azadirachta Leaf Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- Coccinia Indica Fruit Extract plant extract
- Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
- Amber Powder absorbent
- Amber Powder is fossilised tree resin ground fine. It is an inert powder used for texture and finish rather than as an active.
- Mentha Piperita (Peppermint) Leaf Extract plant extract
- Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
- Moringa Oleifera Seed Oil emollient
- Moringa Seed Oil is high in oleic acid and behenic acid and very stable. It is a conditioning emollient with a light, non-sticky finish.
- Magnesium Ascorbyl Phosphate antioxidant
- Magnesium Ascorbyl Phosphate is a stable, water-soluble vitamin C salt. It works at a near-neutral pH, so it suits formulas built for skin that finds pure ascorbic acid stinging.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Betaine Salicylate exfoliant
- Betaine Salicylate is a gentler salicylic derivative. Korean formulas use it at around 2 to 4 percent, which is roughly comparable to a low-strength salicylic acid, and it is easier on the skin barrier.
- Anemarrhena Asphodeloides Root Extract plant extract
- Anemarrhena Asphodeloides is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract.

How it works
A plumper works on how full a lip looks rather than on how it is built, and the format is a balm here rather than a gloss. That means it wears like something that stays on the lips instead of a shine that sits on them. It goes on bare lips whenever you want it, or over lip color as the last layer. Lips that look flat by the afternoon are the case for a step like this, and it can be reapplied through the day. It is a finishing touch rather than a treatment, so it does not replace a balm at night.
How to use
- Use the Refresh AHA BHA Vitamin C Lip Plumper on bare lips, or over lip color as the last layer.
- One pass over each lip straight from the tube, and a second only where lips look driest.
- Nothing needs to go over it, and it sits happily on top of a balm that has already settled.
- Whenever you want it, through the day. Do not use it on cracked or split lips; wait until the surface is intact.
