The Protini Polypeptide Cream refill pod costs less than a new jar and clicks into your existing container. Here's how to swap it and what to expect.
The Protini Polypeptide Cream refill is a sealed replacement pod that drops into your existing Drunk Elephant Protini jar, so you keep the outer container and pump and only replace the moisturizer inside. It holds the same 1.69 fl oz (50 mL) as the original full-size jar and typically sells for a few dollars less. You can buy it at Sephora, Ulta, and the Drunk Elephant website whenever the full-size jar is in stock.
If you searched for a "polypeptide refill" and landed on a page about amino acid chemistry, you are in the right place — this is the cosmetic refill, not a lab term.
What Comes in the Refill Pod
The refill is not a sample or a travel size. The Protini Polypeptide Cream refill contains the full 50 mL of cream in a sealed inner pod, and the formula is identical to the one in the original jar.
- Nine signal peptides, including sh-oligopeptide-1 and several sh-polypeptides, which are the ingredients the product is named for.
- Pygmy waterlily stem cell extract, included for antioxidant support.
- Soybean folic acid ferment extract, used for barrier support.
- Vitamin C–derived antioxidants to help defend against environmental stress.
The cream is fragrance-free and has a light gel-cream texture that most people can wear under sunscreen or makeup. Drunk Elephant packages the refill in the same purple-and-white color family as the original jar, so it is easy to spot on a shelf next to other skin care.
A Quick Word on Peptides
Peptides are short chains of amino acids, and a polypeptide is simply a longer one. Polypeptide structure comes down to amino acids linked end to end by peptide bonds, and the answer to what is the monomer of a polypeptide is the amino acid itself. In skin care, peptides are used as skin-conditioning and humectant ingredients, not as drugs.
Familiar polypeptide examples on cosmetic labels include copper tripeptide-1, palmitoyl tripeptide-1, and the sh-polypeptide family that gives Protini its name. A moisturizer cannot replace a prescription, but peptides can help skin feel hydrated and look a little smoother with consistent daily use.
How to Swap the Refill
Swapping the pod takes about 30 seconds and does not require tools.
- Twist the outer lid off your existing Protini jar and set it aside.
- Lift out the empty inner pod; it should release with a gentle tug once the cream is used up.
- Drop the new refill pod into the outer jar, aligning it so the pump sits flush.
- Replace the lid and prime the pump a few times over a sink or into your hand.
The refill packaging includes an illustration card; follow it if your jar is an older design, since Drunk Elephant has updated the container more than once. Rinsing the empty outer jar with warm water and letting it dry fully before inserting a new pod is optional but keeps things tidy.
Refill vs. Full Jar: What's the Difference
| Feature | Full-Size Jar | Protini Refill Pod |
|---|---|---|
| Product amount | 1.69 fl oz / 50 mL | 1.69 fl oz / 50 mL |
| What you get | Jar, pump, inner pod, lid | Inner pod only |
| Typical price | Highest | Usually a few dollars less |
| Plastic used | Most | Less |
| Best for | First purchase | Restocking an existing jar |
The only real difference between the two is packaging. The Protini refill ships without an outer jar, pump housing, or lid, which is why it costs less and generates less plastic waste.
Cost and Where to Buy It
Prices change with sales and retailer promotions, so check current listings rather than trusting older blog posts. The Protini Polypeptide Cream refill is sold at Sephora, Ulta Beauty, the Drunk Elephant website, and a handful of dermatologist-affiliated retailers.
A few practical notes before you order:
- The refill goes out of stock more often than the full jar, so buying two at once is common.
- Confirm the listing says "refill" rather than "Protini Polypeptide Cream 1.69 oz" — the product photos can look nearly identical.
- The refill is not sold in a mini or travel size; the small jar is a separate product.
- Brand-site bundles and seasonal beauty events are the most reliable times to save.
How It Compares to Other Polypeptide Creams
| Product | Size | Refillable | Fragrance |
|---|---|---|---|
| Drunk Elephant Protini Polypeptide Cream | 1.69 fl oz | Yes | Fragrance-free |
| MyChelle Supreme Polypeptide Cream Unscented | 1.2 fl oz | No | Fragrance-free |
| Sienna Rose Polypeptide Cream | Varies | No | Check the label |
If you are weighing alternatives, mychelle supreme polypeptide cream unscented is a frequent comparison because it is also fragrance-free and peptide-forward, though it comes in a smaller jar and cannot be refilled. Meanwhile, sienna rose polypeptide cream reviews tend to highlight a lighter, budget-friendly texture, but that product is harder to find in US stores. Protini's real advantage is the refill system itself: you keep the pump, so the cost per restock is lower and the plastic footprint is smaller.
Safety and Skin Type Notes
Protini is a cosmetic moisturizer, not a medication, and it is not intended to treat acne, eczema, or any diagnosed skin condition.
- Patch test on your inner forearm for 24 hours before applying it to your face.
- Stop using it if you develop redness, burning, or swelling, and speak with a dermatologist.
- If you are pregnant or breastfeeding, ask your healthcare provider before adding new actives.
- Store the pod at room temperature and use it within the period-after-opening symbol printed on the packaging.
Dry, combination, and oily skin types generally tolerate this cream well because it is fragrance-free, but sensitive skin still deserves a cautious introduction. Anyone using prescription retinoids or acids may want to alternate nights rather than layering everything at once.
Frequently Asked Questions
Is the Protini Polypeptide Cream refill the same formula as the full-size jar?
Yes. The refill pod contains the identical fragrance-free formula and the same 1.69 fl oz (50 mL) of product as the full-size jar. The only difference is that the refill does not include the outer jar, pump housing, or lid.
How much does a Protini Polypeptide Cream refill cost?
The refill is typically priced a few dollars below the full-size jar, and the exact amount varies by retailer and changes during sales events. Check Sephora, Ulta, or the Drunk Elephant site for current pricing before you buy.
How often do you need to buy a new Protini refill?
With twice-daily use on the face and neck, one 1.69 fl oz jar generally lasts about two to three months. Heavier use or sharing the product will shorten that window, so many people keep a spare pod on hand.
