Injectable Calcium Hydroxylapatite (CaHA)
Volume Restoration and Collagen Renewal Treatment
Injectable Calcium Hydroxylapatite (CaHA) is a regenerative treatment that addresses both volume loss and skin quality concerns. In its regular form as a dermal filler, it restores facial contours, lifts sagging areas, and enhances definition, creating a naturally youthful and balanced appearance.
When hyperdiluted, CaHA acts primarily as a collagen stimulator, promoting the skin’s own regenerative processes. Over time, this improves texture, firmness, and elasticity, helping the skin to look revitalised, radiant, and healthier from within.
This dual approach makes CaHA suitable for a variety of concerns — from smoothing fine lines and wrinkles to restoring facial structure and enhancing overall skin health. Ideal for clients seeking both facial enhancement and long-term skin rejuvenation, this treatment supports a refreshed, confident appearance while stimulating the body’s natural collagen production.
Key Benefits of Calcium Hydroxylapatite (CaHA)
While injectable Calcium Hydroxylapatite (CaHA) is often associated with lifting and contouring, its true strength lies in its ability to enhance both facial structure and skin quality over time. Its versatility — whether used in standard or hyperdiluted protocols — allows treatments to be customised to individual needs, providing results that are immediately noticeable as well as progressively enhanced, all while maintaining a fresh, natural appearance.
Lift and Contour Facial Features
In its regular form, Calcium Hydroxylapatite (CaHA) acts as a dermal filler that restores lost volume, lifts sagging areas, and enhances definition in the cheeks, jawline, and other facial features. Its smooth integration with natural tissues ensures results that look like you — just more refreshed.
Immediate lift and volume restoration
Defines facial contours for a more youthful profile
Supports sagging areas for a balanced profile
Blends naturally for a harmonious finish
Stimulates Natural Collagen Production
Unlike conventional fillers, Calcium Hydroxylapatite (CaHA) doesn’t just sit under the skin — it actively stimulates the body’s own collagen production for gradual, long-term improvement.
In its regular form, it delivers both structural support and collagen stimulation
When hyperdiluted, it works solely to trigger collagen renewal without adding volume
Strengthen the skin’s internal support
Improve elasticity, firmness, and overall texture over time
Long-lasting, Natural Results
The improvements from Calcium Hydroxylapatite (CaHA) treatments are designed to be both enduring and subtle. While initial lifting effects are visible right away, collagen stimulation continues to enhance the skin’s structure for months after treatment.
Immediate volumisation with progressive skin improvements
Longevity often exceeding that of hyaluronic acid fillers
Maintains facial harmony without an overdone appearance
Subtle, natural-looking enhancement
Areas Commonly Treated with Calcium Hydroxylapatite (CaHA)
Injectable Calcium Hydroxylapatite (CaHA) is a versatile treatment for enhancing both the face and body. Its dual-action approach — volumising lift in its regular form and collagen stimulation when hyperdiluted — allows our doctors to tailor treatments to each indvidual’s concern:
Facial Contouring & Volume Restoration (regular CaHA)
Cheeks — Restore midface volume and lift sagging areas for a refreshed, youthful appearance
Jawline & Chin — Enhance definition and create a sculpted, balanced profile
Nasolabial Folds & Marionette Lines — Smooth deep folds naturally while maintaining facial harmony
Temples — Replenish lost volume to restore balance and youthful proportions
Skin Rejuvenation & Collagen Stimulation (Hyperdiluted CaHA)
Lower Face & Neck – Stimulate collagen to improve firmness, elasticity, and skin texture
Décolletage & Hands – Enhance skin quality, reduce crepiness, and promote collagen regeneration.
Stretch Marks – Promote collagen regeneration to improve the appearance and texture of stretch marks
Frequently Asked Questions
-
Calcium Hydroxylapatite (CaHA) is composed of microspheres suspended in a biocompatible gel. When injected, it works in two complementary ways:
Immediate structural support: The gel and microspheres restore lost volume, lift sagging areas, and enhance facial contours, providing a refreshed, natural appearance right after treatment.
Collagen stimulation: The microspheres encourage your body’s own fibroblasts to produce new collagen gradually. Over time, this strengthens the skin’s internal support, improving firmness, elasticity, and texture.
When hyperdiluted, CaHA focuses solely on collagen stimulation without adding volume, making it ideal for improving skin quality in areas like the neck, hands, décolletage, or regions affected by stretch marks. This dual action provides immediate lift and long-term skin rejuvenation.
-
Yes. Calcium Hydroxylapatite (CaHA) is an approved injectable treatment in Singapore when administered by trained doctors. It has a well-established safety profile and is widely used in aesthetic medicine worldwide to lift, contour, and stimulate collagen.
CaHA is naturally found in the human body, primarily in bones and teeth, making it highly compatible with tissue and reducing the risk of allergic reactions.
The microspheres in CaHA are gradually metabolised by the body, while the gel carrier is absorbed naturally. Long-term complications are uncommon when treatments are performed correctly by qualified practitioners, ensuring safe and reliable results for both facial contouring and skin rejuvenation.
-
The number of sessions depends on the form of CaHA used and your individual aesthetic goals:
Regular CaHA (dermal filler): For facial contouring and volume restoration, most clients achieve the desired results with a single session. The treatment immediately lifts and sculpts facial features, while the gradual collagen stimulation continues to enhance skin quality over the following weeks.
Hyperdiluted CaHA (collagen stimulator): When the goal is skin rejuvenation, collagen stimulation, or improvement of skin texture and elasticity, multiple sessions may be recommended. Typically, our doctors recommend 2–3 sessions spaced 4 to 6 weeks apart allow for gradual collagen regeneration and progressive improvement in skin quality.
-
The timeline for results depends on the form of CaHA used and treatment goals:
Regular CaHA (dermal filler): Volume restoration and lifting effects are immediately visible, especially in areas like the cheeks, jawline, and chin. Collagen stimulation continues over the following weeks, gradually enhancing firmness, elasticity, and skin texture. This progressive improvement ensures that results look natural and evolving rather than abrupt.
Hyperdiluted CaHA (collagen stimulator): When used to stimulate collagen without adding volume, visible changes appear gradually over several weeks. Skin texture, elasticity, and firmness improve over time, making hyperdiluted CaHA ideal for overall skin rejuvenation in areas such as the neck, hands, décolletage, or stretch marks.
-
The longevity of results varies according to the form of CaHA, treatment area, and individual factors such as skin type and lifestyle:
Regular CaHA (dermal filler): The volumising lift is immediately noticeable, with effects typically lasting 12–18 months. Collagen stimulation continues over time, maintaining skin quality and contributing to a natural, refreshed appearance even as some volume gradually diminishes.
Hyperdiluted CaHA (collagen stimulator): Visible improvements in skin texture, firmness, and elasticity develop gradually over several weeks as collagen regenerates. The effects of hyperdiluted CaHA are long-lasting, generally up to 12 months, though maintenance sessions may be recommended your doctor to support ongoing collagen production and optimal skin rejuvenation.
