Calecim sent me products from their Stem Cell Skincare & Hair Growth Solution collection, and this is not your average skincare brand. The key ingredient comes from stem cell science, and the company behind it started in biotech, not beauty.

Even better, Calecim told me my code stacks on top of their sales, so you can save twice.

PTT-6: The Science Behind Calecim

Every Calecim product is built on one patented ingredient called PTT-6. Their parent company, CellResearch Corporation, is a biotech company that discovered stem cells in the umbilical cord lining about 20 years ago.

Here’s how it works, in plain terms. Stem cells are grown in a lab and then removed, leaving behind the growth factors, exosomes and other proteins they released. That mix is PTT-6, and Calecim says one milliliter contains over 3,000 of these active proteins. The brand’s view is that these proteins act as messengers, signaling your own skin and scalp cells to make more collagen, elastin and hyaluronic acid.

If you’re wondering about the source: the stem cells come from the umbilical cord lining of red deer that are raised organically in New Zealand, and Calecim says the extraction causes no harm or distress to the deer.

The Calecim Hair Serum

Calecim describes the Hair Serum as a 6-week hair restoration program, and says PTT-6 stimulates hair growth by activating the hair follicles and managing the inflammation that causes shedding.

Here’s how the program works:

• The kit comes with an activator to prep your scalp and a derma stamper to apply the serum.
• During the 6-week treatment phase, you use it twice a week, half an ampoule each time. One box lasts the full 6 weeks.
• After that, Calecim suggests a once-a-week maintenance phase, where one box lasts about 3 months.

It’s $360, so it’s a real investment. Calecim is upfront that results vary depending on what’s causing your hair loss, and if your shedding is sudden or getting worse quickly, they recommend seeing a doctor first to rule out an underlying cause.

Healthy hair takes more than one product. I share the two-step approach that has worked for me in how to grow longer, thicker hair.

Calecim Skincare to Try

On the skincare side, these are the best places to start. Every product has PTT-6, just in a different format.

Professional Serum

The Professional Serum is $100 for 5 milliliters, and it has Calecim’s highest concentration of PTT-6. The brand says it targets fine lines, wrinkles and hyperpigmentation, and it’s made to layer with the rest of your skincare.

Apply one pipette to your whole face before your other products. Calecim says you can also use it after at-home microneedling or a chemical peel, or after a treatment at a clinic.

Multi-Action Cream

The Multi-Action Cream is a daily cream that Calecim says boosts collagen and elastin production to lift and firm. It’s $200 for 50 grams, or $68 for a 20-gram starter size, which is a much easier way to try it.

Use it morning and night. If your skin is combination to oily, it can be your moisturizer on its own. If your skin is dry, use it under your moisturizer, and bring it down onto your neck.

Starter Bundle Kit

New to the brand? The Starter Bundle Kit ($115) pairs Calecim’s two best-selling creams, the Multi-Action Cream and the Cooling Hydrating Gel, in starter sizes. Calecim suggests it as the way to try both and pick a favorite for everyday use.

Calecim Questions, Answered

Is there a Calecim discount code?

Yes. Use code ELIZABETH15 for 15% off at Calecim. Calecim told me it stacks on top of their sales, so you take 15% off the sale price.

Why isn’t my Calecim code working?

The most common reason is Auto-Replenish. Those subscription orders already save 20% on full-size products, so other codes don’t apply. Choose a one-time purchase, then enter the code at checkout. Also make sure it’s typed exactly as ELIZABETH15, with no spaces.

Is Calecim worth it?

It’s premium skin and hair care with a biotech backstory, and the prices reflect that. If you’re curious but not ready for the Hair Serum, the Professional Serum or a starter size is a lower-cost way to try PTT-6, especially with the code stacked on a sale.

Does Calecim ship free to the US?

Yes. Shipping is free to the US (state tax may apply in some states), and US orders take about 3 to 6 working days.

Can I return Calecim products?

Only if they’re unopened and unused. Once a product is opened and out of its packaging, Calecim doesn’t accept returns, so a starter size is a smart first buy if you’re unsure.
