CALECIM Professional is a premium, science-led line built around PTT-6, a proprietary blend of proteins secreted by cultured stem cells from red deer umbilical cord lining. The formulas are mostly fragrance-free and well suited to mature and post-procedure skin, but prices are high, concentrations are not disclosed, and returns are limited to unopened products.
What we like
- Clear explanation of PTT-6: proteins secreted by cultured cord-lining stem cells, with no stem cells in the products
- Most formulas are fragrance-free, with unusually specific post-procedure instructions
- Free US shipping with taxes absorbed and a 3 to 6 working day delivery estimate
- Starter sizes of the Multi-Action Cream and Cooling Hydrating Gel lower the cost of a first try
- Backed by a biotech parent company, CellResearch Corporation, founded in 2002
Keep in mind
- Expensive: the 50 g Multi-Action Cream is about $200 and the 5 ml Professional Serum about $100
- PTT-6 concentrations are not disclosed, and several headline figures come from in-vitro lab tests
- Returns only for unopened products, with no refunds for allergic reactions
- The key active is animal-derived (red deer cord lining), so it does not suit vegan routines
CALECIM Professional sits at the clinical end of the skincare aisle. Its formulas are built around PTT-6, a proprietary ingredient the brand describes as a mix of more than 3,000 proteins, including growth factors, cytokines and exosomes, collected from cultured stem cells. The pitch is regeneration: firmer-looking skin, smoother texture, better-supported recovery after procedures such as microneedling or laser resurfacing, and a fresher-looking eye area.
For this 2026 review we looked at the brand's own US store, product pages, FAQ and returns center to see what the range contains, what it costs and what happens if it does not suit you. The short version: the science story is explained more openly than at many brands in this niche, and the formulas are thoughtfully fragrance-free, but you pay a clear premium and the return rules are strict.
Who CALECIM Professional is: a biotech brand focused on regeneration
CALECIM is the skincare brand of CellResearch Corporation, a Singapore-based biotechnology company. The brand's own story says the business was founded in 2002 to supply skin and scar cells for research, and that its scientists identified stem cells in the umbilical cord lining, which the brand calls a rich, non-embryonic source.
The FAQ is specific about where the material comes from: the cord lining is taken from red deer raised in New Zealand, and the brand says collection causes the animals no harm or distress. Importantly, the products do not contain stem cells. PTT-6 is made from the proteins those cultured cells secrete. The brand's philosophy is that science can support skin's own renewal, and its pages state plainly that the products are cosmetics that have not been evaluated or approved by the FDA.
The CALECIM range: a tight edit of serums, creams and a gel
The skincare line is small, which makes it easy to navigate. Nearly every product contains PTT-6, and each one has a slightly different job:
- Professional Serum (5 ml ampoule): the highest PTT-6 concentration in the line, for fine lines, firmness and post-procedure routines.
- Multi-Action Cream (50 g, plus a 20 g starter size): the everyday cream, aimed at laxity, wrinkles and loss of density.
- Eye Contour Lifting Cream (15 ml): for crepey, thinning or puffy skin above and below the eyes.
- Cooling Hydrating Gel (60 g, plus a 30 g starter size): an overnight gel you rinse off in the morning.
- Brightening Complex (30 g): a hydroquinone-free option for uneven tone and dark spots.
- Restorative Hydration Cream: a richer moisturizer designed to layer over the Multi-Action Cream.
A Hair Serum, at about $360, sits outside the skincare line.

Best CALECIM products to start with
For most people, the Multi-Action Cream is the logical first buy. It is used morning and evening, works alone on oily or combination skin, and can go under a moisturizer if your skin is dry. The 20 g starter size, from about $68, is a sensible way to see whether you like the texture and the faint natural scent, which the brand says comes from the actives and fades after application.
If you are planning a professional treatment, the Professional Serum is the product the brand builds its post-procedure protocols around, with clear dosing: one pipette once or twice daily, or more around at-home microneedling. One ampoule yields about 12 to 14 pipettes, which helps put the price in context.
The Cooling Hydrating Gel is a good add-on for dry, stressed skin at night. The brand advises against daytime use because it dries to a film that sunscreen and makeup will not sit over.
PTT-6 and the supporting actives: what to know
According to the brand, PTT-6 combines fibronectins, glycoproteins, collagen and hyaluronic acid with growth factors, cytokines and exosomes. The supporting formulas add familiar ingredients: niacinamide, hyaluronic acid and a soothing peptide complex in the gel; guarana-derived caffeine, niacinamide and peptides in the eye cream; and alpha-arbutin, tranexamic acid, butylresorcinol, glutathione and lactic acid in the Brightening Complex.
Two caveats matter. First, no concentrations are listed for PTT-6 or the other actives. Second, the headline numbers on the Multi-Action Cream page, such as higher elastin and hyaluronic acid production, come from in-vitro tests on skin cells, not human trials. The eye cream cites an investigator assessment over 5 to 7 weeks. These results are encouraging, but they are not the same as large independent clinical studies. The brand says results may take 2 to 4 weeks to appear, with the best results around 90 days.
CALECIM pricing, shipping and returns
CALECIM is firmly premium. In our research, the 50 g Multi-Action Cream was about $200, the Eye Contour Lifting Cream about $160, the Brightening Complex about $148, the 60 g Cooling Hydrating Gel about $115 and the Professional Serum about $100. Starter sizes, from about $60, and a Starter Bundle Kit pairing the Multi-Action Cream with the Cooling Hydrating Gel (about $114) bring the entry point down. An Auto-Replenish subscription is offered on core products, with a minimum of three deliveries.
Shipping to the US is free, and the brand absorbs tax, although state tax may apply in some states. Delivery is estimated at 3 to 6 working days. Returns are tighter than at many brands: products must be unopened and unused in the original box, the window is 30 days from receipt, and allergic reactions are not grounds for a refund. Damaged items need photos within 48 hours, and orders cannot be canceled once placed.
Who CALECIM suits, and who should skip it
CALECIM makes most sense for people with mature skin who want a short, fragrance-free routine focused on firmness and texture, and for anyone working with a clinic on treatments such as microneedling, laser or peels. The brand's instruction to apply products only once skin has fully healed over is a sensible sign that it takes procedure recovery seriously.
It is a poorer fit if you have active, inflamed breakouts, which the brand itself says to avoid, or if you prefer vegan products, since the key active is derived from red deer tissue. Budget shoppers, and anyone who likes the safety net of a satisfaction guarantee, may also want to look elsewhere. If you are pregnant or breastfeeding, the brand says its products are safe but recommends checking with your obstetrician first.
Our verdict on CALECIM Professional
CALECIM Professional offers something genuinely different: a regenerative skincare story rooted in a biotech company with a long history in cord-lining stem cell research. Fragrance-free formulas, detailed post-procedure guidance and free US shipping add to its appeal.
The trade-offs are cost, limited disclosure of concentrations, evidence that leans on lab tests, and a strict return policy. If you are curious, start with a starter size of the Multi-Action Cream rather than the full regimen, and give it the 90 days the brand suggests before judging.

CALECIM Professional FAQs
Is CALECIM Professional legit?
Yes. CALECIM is the skincare brand of CellResearch Corporation, a Singapore biotechnology company founded in 2002, and it sells through its own website and through clinics. As with any premium brand, the real questions are value and evidence rather than legitimacy.
Do CALECIM products contain stem cells?
No. The brand says its products contain PTT-6, a blend of proteins, growth factors, cytokines and exosomes secreted by cultured stem cells from red deer umbilical cord lining. The cells themselves are not in the formulas.
Can I use CALECIM after microneedling or laser?
Several products, especially the Professional Serum and Cooling Hydrating Gel, are designed for post-procedure routines. The brand says products should only go on skin that has fully healed over, which depends on how aggressive the procedure was, so follow your provider's instructions.
Is CALECIM vegan?
No. Its key active, PTT-6, is derived from red deer umbilical cord lining. The brand says collection causes no harm to the animals, but the products are not suitable if you avoid animal-derived ingredients.
Can I return CALECIM if it does not work for me?
Only in limited cases. Products must be unopened and unused in the original box, and the window is 30 days from receipt. Opened products and allergic reactions are not eligible for refunds, so a starter size is the safer first purchase.
How long does CALECIM take to show results?
The brand says some changes may appear within 2 to 4 weeks, with optimal results typically around 90 days. Its instructions assume consistent morning and evening use.
