FOR COSMETOLOGISTS

PROFESSIONAL RECOMBINANT COLLAGEN

KÉRA — professional recombinant collagen for recovery, regeneration, and working with compromised skin.

PHILOSOPHY

A BRAND BUILT FROM PRACTICE

KÉRA is a professional brand created by Nataliya Nenchova — a specialist in aesthetic camouflage, and in working with scars, stretch marks, vitiligo, dermopigmentation, and recovery of compromised skin.

KÉRA was created as a professional solution born from real practice — where the specialist works daily with skin after surgery, trauma, burns, invasive procedures, scars, stretch marks, inflammation, and a compromised skin barrier.

The brand's core philosophy is clear: skin recovery is not an add-on to the procedure — it is part of the professional result.

THE PRODUCT

WHAT IS KÉRA SERUM?

KÉRA Collagen Repair Essence is a professional serum based on recombinant human type III collagen — a medical-grade protein produced through modern biotechnological methods.

This is not a standard cosmetic collagen and not an animal extract. The active ingredient is a recombinant protein produced via yeast, with a high degree of purity and a structure that is 97.5% identical to human collagen.

Thanks to this biological closeness to natural human collagen, KÉRA is suitable for professional protocols aimed at:

recovery
regeneration
improving skin comfort
maintaining an optimal environment for healing processes
working with sensitive, post-procedure, and compromised skin

COMPOSITION

THE COMPOSITION OF KÉRA

KÉRA's formula is minimalist, clean, and built with a focus on professional work with skin that needs recovery.

Recombinant human type III collagen

The serum's core active ingredient. Produced via yeast, with high biocompatibility and a structure that is 97.5% identical to human collagen. It plays a key role for the skin, supporting tissue repair, improved elasticity, dermal structure maintenance, regeneration after damage, recovery after procedures, and improved skin quality in scars and stretch marks.

Glycerin

A hydrating component that helps retain moisture in the skin. Contributes to better hydration, reduced dryness and tightness, greater comfort, and support for the skin barrier function.

Water

The water base keeps the formula light, clean, and suitable for professional use, allowing it to be easily integrated into different protocols — both in-office and as specialist-recommended home care.

FORMULA

WHAT KÉRA DOES NOT CONTAIN

KÉRA is formulated to be maximally gentle on sensitive and compromised skin. The formula does not contain:

fragrances
aromatic additives
heavy oils
aggressive active ingredients
unnecessary cosmetic additives
components that unnecessarily strain the skin

This makes it suitable for skin that is reactive, dry, irritated, recovering, or undergoing professional aesthetic procedures.

STANDARDS

EUROPEAN STANDARD AND SAFETY

KÉRA is a professional product developed with a focus on safety, formula purity, and use on skin with heightened recovery needs.

The product complies with European cosmetic-safety requirements and directives, which is key when working with:

compromised skin
post-procedure skin
scars
stretch marks
skin after invasive procedures
skin after laser
skin after peeling
sensitive and reactive skin

For the professional, this is critically important — when working with such skin, it isn't enough for a product to simply be "active". It needs a clear origin, a clean composition, good tolerability, and a logical place in the professional protocol.

KÉRA was created with exactly that philosophy — as a product that can be integrated both in the treatment room and into specialist-recommended home care.

PACKAGING

PROFESSIONAL PACKAGING, BUILT FOR DAILY PRACTICE

KÉRA Collagen Repair Essence comes in a professional 40 ml package, designed to meet the needs of both in-office specialists and clients using it for home care.

The package features an airless dosing pump that ensures precise, hygienic, and economical dosing with every use. The benefits of this type of packaging include:

an optimal amount of product dispensed with every press
minimal contact of the contents with air and the outside environment
better protection of the formula during use
high hygiene both in the professional treatment room and at home
lower risk of product contamination

Thanks to the light texture and high concentration of the active ingredient, only a small amount of serum is needed per application. This makes KÉRA highly economical for both professional and daily home use.

SHELF LIFE

STABILITY AND SHELF LIFE

The shelf life is 3 years from the date of manufacture.
After first opening, the product can be used for up to 12 months, provided the recommended storage conditions are followed.

The combination of a stable formula, protective airless packaging, and precise dosing helps preserve the quality of the product down to the last drop.

HOME CARE

A PROFESSIONAL PRODUCT FOR HOME CARE

One of the most important aspects of KÉRA is that it is a professional product the specialist recommends to the client for home care.

The result of a procedure doesn't depend only on the technique used in the treatment room — it also depends on how the client cares for their skin afterward. That's why it's essential for the client to use the right product at home, one suited to the procedure, skin condition, and treatment goal.

KÉRA allows the specialist to extend the professional protocol beyond the treatment room through controlled, targeted home care. This is especially important for:

scars
stretch marks
post-procedure skin
skin after microneedling
skin after RF microneedling
skin after laser
skin after peeling
skin after dermopigmentation
sensitive skin with a compromised barrier

When the client uses the recommended professional product, the specialist has better control over the recovery process and can build a more consistent therapeutic strategy.

cosmetologists

APPLICATIONS

PROFESSIONAL APPLICATIONS OF KÉRA

Scars

KÉRA can be incorporated into professional protocols for various types of scars: surgical scars, scars from trauma, burn scars, post-acne scars, hypertrophic scars, old scars, fresh scars from closed wounds, and scars from aesthetic and surgical interventions. The product supports the skin during recovery by creating better conditions for hydration, comfort, and a regenerative environment.

Stretch marks

For stretch marks, KÉRA can be part of protocols aimed at improving skin quality, density, and elasticity. It is suitable for: new red stretch marks, old white stretch marks, stretch marks after pregnancy, stretch marks after rapid weight change, and stretch marks on the thighs, abdomen, hips, chest, and arms.

After microneedling

After microneedling, the skin goes through a controlled healing response. KÉRA can be used as part of post-procedure care to support soothing, hydration, the recovery process, reduced dryness and tightness, and an optimal environment for regeneration.

After RF microneedling

KÉRA can be included in professional RF microneedling protocols, with one important caveat: recombinant collagen is sensitive to prolonged heat exposure. At temperatures above approximately 42°C sustained for more than 30 minutes, the collagen's biological activity may gradually decrease. For RF procedures, it is therefore recommended to work with gentle, controlled parameters and avoid excessive or prolonged tissue heating.

Electroporation and ion transport

KÉRA can be combined with gentle transdermal delivery methods such as electroporation and ion transport. There are currently no specific laboratory tests for its interaction with particular devices, so prior testing and adapting the parameters to the device, procedure, and skin type is recommended. Practical experience shows positive results in terms of hydration, comfort, and faster recovery after the procedure.

After laser procedures

KÉRA can be included in aftercare following aesthetic laser procedures, when the skin needs soothing, hydration, and recovery. It is suitable after: CO2 laser, fractional lasers, laser procedures for scars, laser procedures for texture, and laser procedures that leave the skin dry or uncomfortable.

After chemical peel

After a chemical peel, the skin is often sensitive, dry, and has a temporarily compromised barrier function. KÉRA can be used as a recovery product after the procedure when the specialist aims to reduce discomfort, maintain hydration, support the skin barrier, and improve post-procedure comfort.

After PMU and dermopigmentation

PMU artists can use KÉRA as part of aftercare following procedures where the skin undergoes controlled micro-trauma. It is suitable after: permanent makeup, dermopigmentation, aesthetic camouflage, work on scars, work on vitiligo, and lip procedures.

Compromised skin barrier

KÉRA is suitable for skin showing signs of a compromised barrier function: dryness, tightness, flaking, sensitivity, reactivity, discomfort, redness, and recovery after aggressive procedures.

Acne and post-acne

For acne or post-acne skin, KÉRA can be included as part of restorative care, especially when the skin is dried out, irritated, or treated with active therapies. It is suitable for: post-acne marks, a compromised barrier after active therapies, sensitivity after peels, acne scars, and dryness after dermatological products.

Atopic and sensitive skin

The minimalist, fragrance-free formula makes KÉRA a suitable choice for skin that cannot tolerate heavy, aggressive formulas. It can be used as supportive care for: atopic skin, severe dryness, sensitivity, reactivity, flaking, and impaired comfort.

Burns and sun damage

KÉRA can be applied to skin that needs recovery after sunburn or superficial damage, when the skin has no active open wound and the specialist determines the product is appropriate. The goal is to support comfort, hydration, recovery, and reduced dryness and tightness.

LOGIC

THE PROFESSIONAL LOGIC OF APPLICATION

KÉRA should not be viewed as an ordinary cosmetic serum. It is part of a professional approach in which the specialist evaluates:

the condition of the skin
the type of damage
the age of the scar or stretch mark
the sensitivity of the area
previous procedures
the skin's recovery capacity
home care
the client's realistic expectations

The best results are achieved when KÉRA is included in a complete protocol, rather than used haphazardly.

METHOD OF USE

HOW IS KÉRA APPLIED?

KÉRA can be used:

immediately after a procedure, when the protocol allows it
as post-procedure care
as home care between procedures
on dry and sensitive skin
on scars and stretch marks
after invasive and device-based procedures
on skin that needs recovery

In professional practice, the frequency of application is determined by the condition of the skin and the goal of the therapy.

WHY KÉRA

WHY DOES KÉRA MATTER FOR PROFESSIONAL PRACTICE?

Because today's client is no longer looking for just a procedure. They are looking for:

faster recovery
less discomfort
better aftercare
an individual approach
a visible change in skin quality
trust in the specialist

KÉRA allows the professional to offer a more complete and responsible approach to skin — not just working on the problem, but also caring for its recovery afterward.

HOME CARE

KÉRA — WHEN PROFESSIONAL CARE CONTINUES AT HOME

The professional procedure begins in the treatment room, but the result continues to build at home.

That's why the recommended home care isn't a formality — it's part of the professional protocol.

When the specialist recommends KÉRA to the client for home use, it gives them a way to maintain their skin with a product suited to the procedure, the recovery process, and the goal of the therapy.

This is especially important when working with scars, stretch marks, and compromised skin, where consistency and proper care between procedures matter enormously.

KÉRA is a professional product created not just to be used after a procedure, but to continue the care where the treatment room leaves off — at home.
