Concentrated PTT-6® Serum for Post-Procedure Skin, Firmness & Visible Skin Renewal

CALECIM® Professional Serum is an advanced, lightweight serum formulated with the highest concentration of PTT-6® in the CALECIM skincare range. Originally developed for use alongside professional aesthetic treatments, it is designed for mature, sensitized and post-procedure skin, as well as anyone looking to improve the visible quality, firmness and resilience of their complexion.

At the centre of the formula is PTT-6®, CALECIM’s proprietary complex of bioactive signalling proteins, including growth factors, cytokines and structural proteins. The fast-absorbing, fragrance-free formula helps skin appear smoother, firmer, more even and refreshed while providing lightweight hydration without a heavy or occlusive finish.

Professional Serum can be incorporated into a daily skincare routine or used as part of a professionally guided post-treatment protocol following procedures such as microneedling, RF microneedling, laser resurfacing and chemical peels.

Recommended For
  • Mature skin and visible signs of skin aging
  • Fine lines and wrinkles

  • Dull or fatigued-looking skin
  • Thin or sensitized-feeling skin
  • Post-procedure skincare
  • Skin undergoing professional microneedling, RF microneedling, laser or resurfacing treatments
  • Clients looking for an advanced growth factor and bioactive protein serum

Professional Serum is suitable for all skin types. CALECIM does not recommend applying it over active inflammatory acne or open acne lesions.

What Makes CALECIM Professional Serum Different?

Professional Serum contains the highest concentration of PTT-6® within CALECIM’s skincare collection, making it the brand's most concentrated option for clients looking for targeted support for visible skin renewal and post-procedure care.

Unlike a conventional hydrating or peptide serum, CALECIM Professional Serum is centred around bioactive cell-signalling proteins.

What Is PTT-6®?

PTT-6® is CALECIM’s proprietary technology developed through regenerative medicine research using ethically sourced umbilical cord lining stem cells.

The complex contains a broad spectrum of naturally occurring bioactive signalling molecules, including growth factors, cytokines and proteins involved in cellular communication, alongside components such as:

  • Glycoproteins
  • Soluble collagen
  • Albumin
  • Fibronectin
  • Hyaluronic acid

The finished Professional Serum does not contain stem cells.

In skincare, PTT-6® is used to support the appearance of healthier, smoother, firmer and more resilient skin, particularly when the skin is showing visible signs of aging or temporary stress following an aesthetic procedure.

Professional Serum & Post-Procedure Skincare

CALECIM Professional Serum was originally developed for use by physicians and aesthetic practitioners following professional treatments.

It is commonly incorporated into protocols involving:

  • Microneedling
  • RF microneedling
  • Laser resurfacing
  • Chemical peels
  • Dermabrasion
  • Other professionally administered resurfacing treatments

These procedures temporarily place the skin into a heightened state of renewal. Professional Serum is designed to complement this period with concentrated PTT-6® while helping the skin appear comfortable, hydrated and healthy throughout the visible recovery process.

The appropriate timing for applying skincare after a procedure depends on the treatment performed. Always follow the post-care instructions provided by your treating physician, facialist or skincare professional.

How to Use

As a Daily Serum

Apply approximately one pipette to freshly cleansed skin.

Gently distribute over the face and allow the serum to absorb before applying additional serums, moisturizer or facial oil.

During the day, finish with broad-spectrum sunscreen.

After a Professional Treatment

Professional Serum may be incorporated into a post-procedure protocol following treatments such as microneedling, RF microneedling, laser resurfacing or chemical peels.

Depending on the treatment, your practitioner may apply the serum professionally and recommend continuing with it at home during the days following your appointment.

Always follow the specific post-treatment instructions provided by your treating professional.

Loshen & Crem's Recommendation

We think of CALECIM Professional Serum differently from an everyday hydrating serum.

This is the serum we reach for when the skin needs something more focused: after an advanced treatment, when the complexion is looking particularly depleted, or when mature skin is beginning to show changes in firmness, texture and overall skin quality.

Its exceptionally light texture is also one of its strengths. You receive a highly concentrated treatment without adding another rich or heavy layer to the routine, making it easy to combine with the skincare you already use.

For clients undergoing a series of advanced treatments, we especially like Professional Serum as part of a thoughtfully planned homecare routine before and after appointments.

CALECIM Professional Serum vs. Recovery Night Complex

Both formulas contain CALECIM's PTT-6® technology, but we recommend them differently.

Professional Serum is the more concentrated, lightweight option. It contains the highest concentration of PTT-6® in the CALECIM skincare range and is particularly well suited to professional protocols, post-procedure routines and clients wanting an intensive treatment serum.

Recovery Night Complex has a more protective gel-like texture that creates a light film over the skin. We prefer it as an evening product when additional comfort and hydration are desired.

For certain post-treatment routines, the two can also be layered together: Professional Serum first, followed by Recovery Night Complex, when recommended by your skincare professional.

Ingredients
  • PTT-6®: CALECIM's proprietary bioactive protein complex containing glycoproteins, soluble collagen, albumin, fibronectin, hyaluronic acid and naturally occurring signalling molecules. It is the signature technology behind the CALECIM Professional skincare collection.
  • Hyaluronic Acid: A naturally occurring humectant that helps attract and retain moisture, supporting a hydrated, supple and smoother-looking complexion.

It contains the highest concentration of PTT-6® in CALECIM's skincare range and can be incorporated into both daily homecare and professionally guided post-treatment routines.

Is CALECIM Professional Serum a growth factor serum?

CALECIM Professional Serum contains PTT-6®, a proprietary complex containing naturally occurring growth factors, cytokines and other bioactive signalling proteins developed from ethically sourced umbilical cord lining stem cell research.

The finished serum does not contain stem cells.

Can I use CALECIM Professional Serum after microneedling?

Yes. Professional Serum was originally developed for professional aesthetic protocols and is commonly incorporated into skincare following microneedling and RF microneedling.

The appropriate time to apply the serum depends on the treatment performed, so follow the post-care protocol provided by your treatment professional.

Can Professional Serum be used after laser treatments or chemical peels?

CALECIM Professional Serum is commonly used as part of professionally directed skincare following resurfacing procedures including certain laser treatments and chemical peels.

Because post-procedure requirements vary considerably, follow the instructions provided by the professional who performed your treatment.

Can I use CALECIM Professional Serum every day?

Yes. Professional Serum can also be used independently of professional treatments as part of a daily skincare routine.

Apply approximately one pipette after cleansing and before moisturizer.

Can I use Professional Serum with retinol or vitamin C?

Professional Serum can generally be layered with ingredients including vitamin C, retinoids, niacinamide, peptides and other serums.

If you have recently undergone an aesthetic treatment, your usual active ingredients may need to be temporarily paused. Follow the post-treatment instructions provided by your skincare professional.

Is CALECIM Professional Serum suitable for sensitive skin?

CALECIM describes Professional Serum as suitable for sensitive skin. Its lightweight formula is fragrance-free and was originally developed with post-procedure skin in mind.

Clients with highly reactive skin, known allergies or an active skin condition should consult their healthcare or skincare professional before introducing a new product.

Can Professional Serum be used on acne-prone skin?

Professional Serum is not intended to treat acne and CALECIM does not recommend using it directly over active inflammatory acne or open acne pustules.

It may be incorporated into professionally guided routines focused on the visible appearance of post-acne marks or textural irregularities once active breakouts have settled.

What is the difference between CALECIM Professional Serum and Multi-Action Cream?

Professional Serum is CALECIM's more concentrated PTT-6® treatment and is particularly well suited to targeted routines and post-procedure skincare.

Multi-Action Cream combines PTT-6® technology with the comfort and emollience expected from a daily moisturizer and is better suited to clients wanting ongoing daily moisturization alongside CALECIM technology.

The two can also be layered, with Professional Serum applied first.

Why is CALECIM Professional Serum pink?

The colour of Professional Serum can naturally range from yellow-orange to pink or deeper pink. CALECIM explains that the formula contains a pH indicator and that slight variations between batches may influence its colour.

This variation is normal.

Game-Changer for my skin

After only a week of usage, I have noticed a visible improvement in my skin’s texture, hydration, and overall glow. My skin feels smoother, healthier, and more refreshed. I am impressed with the difference it has made. Calecim is a game-changer for my skin.

Impressed so far

I haven't been using it long enough for real results, but the mornings after the nights I have used it - my skin has been magical.

Super smoothing and soothing. Skin seems much stronger.

Worthwhile investment

After only 2 weeks it’s hard to know the longer results but I feel my skin has a more glowing appearance youthful feel- bit bouncier, healthier and less saggy . It hasn’t done any miraculous reduction of major lines but so far I’m satisfied this is making a difference. I’m eager to see how it goes after a few months and I trust the science behind this product .

I love it

I honestly really don’t know what it does but it makes my skin phenomenal and definitely helps with tightness and wrinkles for the price. I thought I’d try it once but now I’m hooked. I just buy the six pack. It’s like gold to

Effective serum

I have been using Calecim products for few months now . I love everything that i have tried so far . This serum however is one of the best . I use it daily and can honestly see big improvement in my skin . One is improvement in my skin firmness all over my face around the mouth , jowls and also the neck area . The lines in my forehead is less visible . I am not complaining with the plumpness of my skin either . Marionette lines are less noticeable as well. The radiance of my skin and smoother texture and more even complexion . Expensive but worth it .

Calecim Serum

I have used one vial and starting the 2nd. I am very impressed that already I see results specifically around my eye area.

So far so good, I think.

The bottle is so tiny and I'm amazed that after two weeks, I still have half a bottle left. I only use this once a day in my nighttime routine. I use it before the multi-action cream which is also potent so I can't credit this product alone for the changes I'm seeing. I've also read that it is most effective after micro-needling and laser procedures, so I'm not really sure how penetrative it is as a daily use serum. I also find it hard to spread on a dry face so I make sure my face is slightly damp when I apply it. I have no idea if this hinders the effect. It's extremely expensive so I think my future purchases will be creams, rather than this serum.

For Bulletproof Skin

This product goes a long way (I can cover my entire face and eyelids with less than one dropper) and it works better than anything else to make my skin more resilient to tolerate harsh actives and to recover quickly. Highly recommend!

Now that I have the hang of applying this serum I just love it. Skin feel is instantly firm! Have only been using for about three weeks, but I can’t wait to see more changes with longer use!

Not impressed

There is so little of this product than I decided to use it every other day and only in the morning. It doesn’t leave my skin feeling any particular way. I think it must be doing something but it is hard to say with the amount provided. I will not buy again.

Loshen you are the best!

I’ve been a loyal customer of Loshen & Crem for a while now, and they never cease to impress me with their curated selection of top-tier skincare products. I was thrilled to discover that they now carry Calecim, a brand I've heard so much about.

As always, the shopping experience at Loshen & Crem was seamless. Their customer service is exceptional—they truly go above and beyond to make sure you’re satisfied. The team is knowledgeable and always ready to offer personalized advice, which is so rare to find these days.
