Squeezable lip oil that delivers glossy shine and a plumping effect using castor oil and pomegranate sterols rather than synthetic plumping agents like capsaicin or hyaluronic acid fillers. As a non-toxic lip plumpers option, it relies on plant and animal-derived fats to hydrate and volumize.
Versatile enough to wear three ways: on its own for a glossy, glass-like finish, layered over a tinted lip balm for shine plus color, or applied before bed as an overnight lip treatment.
The formula leans heavily on animal-based fats (tallow and lanolin) that are structurally similar to the oils your skin already produces, which is central to Primally Pure's approach. If you prefer fully plant-based lip care, this isn't it.
Pomegranate sterols serve as the moisture-barrier ingredient here, doing the job that petrolatum or synthetic occlusives handle in conventional lip products. They lock moisture in without a waxy, heavy feel.
Primally Pure sources its lanolin from pasture-raised, grass-fed sheep in New Zealand and its tallow from grass-fed cows, so the sourcing chain is specific and traceable rather than generic commodity supply.

Works on both the lips and their contour, where the surrounding skin is thinner, fragile, and prone to fine lines from intense muscular activity.
Low-molecular-weight hyaluronic acid retains moisture for hydration, while tripeptide supports collagen and elastin synthesis for a firmer, smoother-looking lip area.
Suited to dry or dehydrated lips, lips lacking volume, and dehydration lines around the mouth; it also helps create a fuller appearance and smooth the contour.
The oil has a naturally light yellow-to-amber color and a slight nutty scent, with no added fragrance listed.

How to Swap to Non-Toxic lip plumpers:

Here's how to swap to non-toxic lip plumpers:

What to know about lip plumper

Lip plumpers sit directly on one of the most absorbent areas of your body and are easily ingested throughout the day. Welpr looks at the full formula — ingredients, fragrances, pigments, and preservatives — to make sure nothing unnecessary or concerning ends up on your lips.

Because lips have thinner skin and are close to your mouth, what's in the formula deserves a close look.
Ingredients like synthetic fragrance, harsh preservatives, and certain plumping agents can be absorbed or swallowed with normal use.

Review what you already use

Check the lip plumpers you currently own using the Welpr Personal Care and Cosmetic Scanner. It takes a picture of the ingredient label and flags anything that doesn't meet Welpr's standards.

Start with the lip plumper you reach for most often, since frequent use on your lips means more daily exposure.
Look at the ingredient list for words like "fragrance," "parfum," or long lists of synthetic additives — these are common in conventional lip products.

Use your current lip plumper more mindfully

If you're not ready to replace your lip plumper right away, small changes in how often and how much you apply can make a difference.

Try limiting application to once or twice a day instead of frequent touch-ups, since lips absorb ingredients quickly.
Avoid licking your lips right after applying to reduce how much product you ingest.

Choose a cleaner lip plumper

Look for lip plumpers with simple, intentional formulas. The best options use natural plumping ingredients like peppermint oil or plant-based peptides and skip synthetic fragrance, parabens, and harsh preservatives.

Prioritize products that are fragrance-free or scented only with essential oils, and check for certifications like EWG VERIFIED™ or MADE SAFE® as a helpful starting point.
