Introduction
Wrinkles and volume loss are not the only signs of skin ageing. As collagen and elastin levels decline, your skin may also become drier, thinner, and less firm, leading to a rougher or more crepey texture.
This is where the Hyaluronic Acid (HA) Calcium Hydroxylapatite (CaHA) Amino Acid Skin Booster comes in, combining deeper hydration with collagen stimulation. Unlike dermal fillers, skin boosters do not reshape the face or replace lost volume. Instead, they focus on supporting hydration and improving overall skin quality, firmness, and resilience to everyday environmental and ageing-related stressors.
Below, we explain how HA CaHA Amino Acid Skin Booster works, what patients can expect during and after the procedure, and who may be suitable for the treatment.
Key Takeaways
- The HA CaHA Amino Acid Skin Booster combines HA to support hydration, CaHA to stimulate collagen and elastin production, and amino acids that play a role in collagen formation.
- It may be considered for those concerned with dryness, fine lines, crepey texture, reduced firmness, and mild skin laxity.
- This skin booster treatment focuses on improving skin quality rather than restoring facial volume or reshaping contours.
- Treatment involves multiple small injections across the target area. Tiny bumps or needle marks may appear and resolve within a few hours to a few days.
- A medical assessment is important to determine whether the skin booster is suitable for you.
Exploring the HA CaHA Amino Acid Skin Booster and its components
The HA CaHA Amino Acid Skin Booster is an injectable treatment that is made of three main components: HA, CaHA, and amino acids. Each of these performs different roles within the skin.
Hyaluronic acid (HA): Improves skin hydration
Hyaluronic acid is a naturally occurring molecule in the body that attracts and retains water. In the HA CaHA Amino Acid Skin Booster, it helps improve hydration from within, which can help smooth rough texture and make fine lines less noticeable.
HA CaHA Amino Acid Skin Booster contains non-cross linked HA, which differs from the crosslinked HA used in certain other skin boosters. Non-crosslinked HA molecules are not chemically linked together resulting in a more fluid formulation that supports skin hydration rather than providing structural volume.
Crosslinked HA skin boosters have a different formulation and may serve different treatment purposes. Depending on the product, they may be used to improve hydration, provide skin plumping, or offer additional tissue support. One example is the HA Vital Light Skin Booster. A doctor can assess your skin concerns and recommend a suitable skin booster.
Calcium hydroxylapatite (CaHA): Supports collagen and elastin production for firmer skin
Calcium hydroxylapatite consists of biodegradable microspheres that stimulate fibroblast activity after injection. Fibroblasts produce collagen, which gives the skin strength and structure, and elastin, which allows it to stretch and return to shape.
In the HA CaHA Amino Acid Skin Booster, CaHA complements the hydrating effects of HA and supports collagen and elastin production over time.
Amino acids: Components involved in collagen synthesis
Amino acids, such as glycine and L-proline, are involved in protein synthesis and are important constituents of collagen, one of the main structural proteins in the skin’s extracellular matrix (ECM). The ECM is the network of proteins and other molecules surrounding our skin cells that provides structural support and helps maintain hydration.
The amino acids in this skin booster complement the collagen-stimulating action of CaHA and support gradual skin rejuvenation.
Who is suitable for HA CaHA Amino Acid Skin Booster?
If you have been following a regular skincare routine but have started to notice changes in your skin quality, you may wish to consult a doctor to find out whether skin boosters are suitable for you. Dehydrated or dull-looking skin, fine lines, uneven texture and skin laxity are common concerns that can become more noticeable with ageing and environmental exposure.
While different skin boosters address different concerns, the HA CaHA Amino Acid Skin Booster is designed to support skin hydration and quality, alongside collagen-related processes.
You may want to ask your doctor about this skin booster treatment if you have the following concerns:
- Crepey texture: The skin appears crinkled, with many tiny, shallow creases that may become more noticeable when the skin is stretched or moved.
- Reduced firmness: The skin may feel less firm or appear less resilient than before.
- Fine lines: Fine lines that remain noticeable even when the skin is well hydrated.
- Increasing dryness: The skin feels less supple or becomes dehydrated more easily.
- Mild skin laxity: The skin shows some looseness, although more pronounced laxity may require a different treatment approach.
- Thinner-looking skin: Age-related decline in collagen and elastin can make the skin appear thinner.
Common treatment areas for the HA CaHA Amino Acid Skin Booster treatment include the face and neck.
How does the HA CaHA Amino Acid Skin Booster work?
Detailed consultation before treatment
The treatment process begins even before the first injection. At Halley Medical Aesthetics, our doctors will conduct a detailed assessment to determine whether the skin booster is a good fit for your skin concerns.
The doctor will assess your skin quality and treatment areas, taking into account your skin thickness, degree of laxity, previous procedures, medical conditions and medications. This allows doctors to identify any factors that could affect treatment or recovery.
What happens during treatment?
During the session, we will cleanse the treatment area and apply a topical numbing cream to help minimise discomfort. The doctor will then mark the injection points based on the treatment area.
They will administer the HA CaHA Amino Acid Skin Booster using a hand-injection technique, which involves multiple small intradermal injections spaced evenly across the treatment area. Injecting the skin booster manually allows the doctor to control the depth of each injection and adjust the amount delivered at each point according to the skin thickness and treatment area, helping to distribute the skin booster more evenly across the skin for consistent treatment.
You will feel a series of small pricks during the procedure. After the injections, the doctor may gently massage the treated area if appropriate. The duration of the session will depend on the size and number of areas being treated.
Downtime and aftercare
Tiny bumps or needle marks may appear at the injection sites after treatment. These will usually settle within a few hours to a few days. Mild redness or bruising may also occur. Follow your doctor’s advice on when it is safe to apply makeup to the treated area.
After treatment, your doctor may advise you to:
- Avoid makeup immediately after treatment to reduce the risk of irritation or infection at the injection sites.
- Avoid alcohol for 24 hours, as advised by your doctor, as it may increase the risk of bruising.
- Avoid aspirin and similar blood-thinning painkillers unless medically necessary, as they can increase bruising or swelling.
- Keep exercise light and avoid vigorous exercise for 24 hours to minimise the chance of bruising.
- Stay away from saunas, steam rooms, and excessive heat, as it can dilate blood vessels and increase the chance of bruising or bleeding
Make sure to follow the aftercare advice given by your doctor, as recommendations can differ according to your skin and the area treated.
What are the side effects of HA CaHA Amino Acid Skin Booster?
Before treatment, it is important to understand the potential side effects of the HA CaHA Amino Acid Skin Booster, including common temporary effects and rarer complications.
Temporary side effects
Bruising, tenderness, mild swelling or puffiness, and redness (erythema) at the injection sites are common side effects of the injection process. These effects usually improve as the skin heals.
Small raised bumps and areas of unevenness may be visible at the injection site after treatment. These are usually temporary and will settle within a few hours to a day after treatment.
Infection
Infection after injectable treatment is rare, but any procedure that breaks the skin carries a small risk because bacteria can enter through the injection sites before they have fully healed. This is why proper skin preparation, aseptic injection techniques, and appropriate post-treatment care are important. Having the procedure performed by a qualified doctor also allows any signs of infection to be assessed and treated promptly if they occur.
Signs to look out for include increasing pain, warmth, redness, swelling, tenderness, or discharge from the treated area, particularly if these symptoms worsen instead of settling over time.
If you notice any of these changes, seek medical attention promptly.
Vascular complications
Vascular complications are rare but potentially serious. They may occur if the injected product enters a blood vessel and obstructs blood flow to the surrounding tissue.
Warning signs can include severe or unusual pain, skin that turns pale or develops a mottled appearance, worsening discolouration, or changes in vision. If any of these symptoms occur, seek medical attention immediately.
This is why the procedure should be performed by a doctor who is trained in facial anatomy, injection techniques, and the recognition and management of vascular complications.
Frequently asked questions
1. How long does the HA CaHA Amino Acid Skin Booster last?
The results of the HA CaHA Amino Acid Skin Booster typically last around three to four weeks. Our doctors usually recommend an initial course of three monthly treatments, followed by maintenance sessions approximately every six months for optimal results.
2. Can I continue my regular skincare routine after skin booster treatment?
Yes you may apply your daily skin after a skin booster treatment. But avoid excessive rubbing, scrubbing, exfoliating your skin, or applying products that may irritate the treated skin.
Your doctor may also advise you to temporarily stop using products containing retinoids, exfoliating acids or other resurfacing ingredients until the injection marks have improved. This is to avoid causing irritation to the skin. Speak with your doctor if you are unsure or have any concerns.
3. What treatments can you combine HA CaHA Amino Acid Skin Boosters with?
The HA CaHA Amino Acid Skin Booster may be combined with other treatments, such as:
- Botulinum toxin: Botulinum toxin treatments can help soften expression lines, such as forehead lines and crow’s feet, by reducing muscle activity in selected areas.
- Laser skin rejuvenation: Laser treatments can address concerns such as pigmentation, uneven tone, or textural irregularities that a skin booster does not directly target. For example, fractional laser resurfacing can be used to improve rough texture and selected acne scars, while pico laser treatment can help reduce the appearance of pigmentation.
- Non-invasive skin tightening treatments: You may consider skin tightening treatments like Ultherapy PRIME, XERF, Exilis Ultra 360, and HIFU to address more noticeable skin laxity. These technologies deliver energy at selected depths to stimulate collagen remodelling, which may gradually improve skin firmness and laxity.
- Korean ECM Skin Booster: The Korean ECM Skin Booster may be combined with the HA CaHA Amino Acid Skin Booster as part of Halley’s Triple Complex Skin Booster treatment. This combination may be considered for concerns such as reduced firmness, uneven texture and early changes in skin density. This treatment uses human acellular dermal matrix (hADM), which contains ECM components such as collagen, elastin, and glycosaminoglycans.
Our doctor will determine which treatments to combine, as well as their timing and sequence, based on your skin condition, treatment areas, previous procedures and desired outcomes.
4. Are HA CaHA Amino Acid Skin Boosters the same as dermal fillers?
No. The main differences lie in what they are designed to treat.
The HA CaHA Amino Acid Skin Booster focuses on improving skin hydration, firmness, elasticity, and texture without altering facial structure. On the other hand, dermal fillers are used to restore volume, support facial structure, and enhance facial contours
Conclusion
The HA CaHA Amino Acid Skin Booster takes a multi-component approach to skin quality. HA improves hydration, CaHA stimulates collagen and elastin production, and amino acids provide building blocks used in collagen formation. Together, these components support the extracellular matrix (ECM) by helping maintain the skin’s hydration, structure, firmness, and elasticity. This makes the skin booster treatment suitable for concerns such as dryness, fine lines, crepey texture, and reduced firmness.
However, other signs of ageing may require different treatments. Volume loss, deeper tissue laxity, pigmentation, and expression lines may require a different approach. At Halley Medical Aesthetics, we offer a range of injectables, lasers, and energy-based treatments to address these different aspects of skin ageing.
