Hyaluronic Acid (Dermal Filler) Injections
Hyaluronic acid (dermal filler) injections can restore volume in nasolabial folds, tear troughs, lips, and hollow areas of the face—offering natural, reversible results as one of today's mainstream non-surgical facial rejuvenation options.
Key Takeaways
- Hyaluronic acid is a naturally occurring hydrating component of the dermis; once injected it instantly fills facial hollows and smooths wrinkles, with results typically lasting 6 months or longer.
- HA injections are reversible—the product is metabolized naturally in the body with no residue, making it a non-permanent treatment.
- Common applications include nasolabial folds, tear troughs, marionette lines, lip shaping, and acne scar filling across multiple facial areas.
- Within the first week after injection, avoid touching the treated area; do not apply makeup within 24 hours; and avoid high-heat saunas and strong UV exposure for two weeks.
- Choosing a properly licensed physician and clinic, and verifying the product's authenticity code before injection, are key steps to ensuring a safe treatment.
Direct Answer
Hyaluronic Acid (HA) is a naturally occurring hydrating component in the dermis of human skin, with an exceptional water-binding capacity—1 gram of HA can hold about 500 ml of water. As we age, hyaluronic acid in the skin gradually depletes, leading to reduced collagen, skin laxity, and wrinkles. By injecting HA into targeted areas, volume can be restored instantly and wrinkles smoothed, with results typically lasting 6 months or longer. At ID Cosmetic Clinic in Markham/Toronto, treatments are led by Dr. Dan Xu (MD, CCFP), who understands the differences between North American aesthetics and Asian facial bone structure and offers personalized HA plans that address concerns common to Asian faces, such as a flatter profile and lack of dimension. Common uses include softening nasolabial folds and marionette lines, filling hollows like tear troughs, temples and cheeks, refining lip contours, and filling acne scars—and because HA is biodegradable and reversible, it typically leaves no residue.
Hyaluronic Acid (Dermal Filler) Injections

1. Reducing Wrinkles
Aging, smoking, compression from sleeping positions, and the constant pull of gravity all contribute to the loss of hyaluronic acid in the skin. This gradually reduces the collagen and elastic fibres in the dermis, leading to skin laxity and facial wrinkles. Hyaluronic acid injections can effectively address a variety of wrinkles:
2. Facial Volume Restoration
Aging changes the distribution of subcutaneous tissue, causing hollowing in the temples, cheeks, eye sockets, brow ridge, and around the lips, as well as the appearance of tear troughs. Hyaluronic acid is a popular and effective option for facial filling, including tear troughs, nasolabial folds, and marionette lines.
3. Filling Depressions and Scars
Hyaluronic acid can also be used to fill acne scar depressions, scars from injury or surgery, and asymmetries caused by congenital defects.
How Long Do Hyaluronic Acid Filler Results Last?
The results of hyaluronic acid filling and contouring generally last 6 months or longer. In addition, hyaluronic acid has a strong water-binding capacity—1 gram of hyaluronic acid can hold about 500 cc of water, roughly 500 times the water-holding ability of glycerin, which makes it a widely recognized hydrating ingredient. Combined with its ability to stimulate collagen production, injecting hyaluronic acid not only plumps hollow areas but also gives the skin elasticity and a healthy glow.
Advantages of Hyaluronic Acid Injections:
1. High Safety: Hyaluronic acid wrinkle correction requires no surgery—only injection into the dermis—avoiding surgical risks. Results are immediate, natural-looking, and the procedure has a high safety profile.
2. Reversibility: It is biodegradable and non-permanent, with no concern about residual material. After being broken down through metabolism, its effect wears off and everything returns to its natural state, usually without lasting after-effects.
3. Comfortable with Minimal Pain: This minimally invasive procedure uses injection, similar to a regular shot, with only slight swelling and mild discomfort in the treated area—no significant pain.
4. Natural Results: Hyaluronic acid wrinkle correction produces natural results. Whether deep or mid-level wrinkles, they can be effectively smoothed without stiffening facial expressions.
Aftercare
1. Do not touch the treated area within one week of injection;
2. Avoid strenuous exercise after injection;
3. Do not apply makeup within 24 hours of injection;
4. Try to avoid saunas and UV exposure for 2 weeks after injection;
5. You may eat light foods after injection;
6. A cold compress may be applied to the treated area as appropriate after injection.
Therefore, whichever area you wish to improve and whatever brand you choose, it is best to proceed under a physician’s guidance. To avoid any unexpected issues from counterfeit products, before injection you can scan the code or enter the serial number on the product’s official website to verify authenticity. Choosing a legitimate, licensed clinic and rejecting unlicensed practices such as underground clinics or personal studios is also the most reliable way to avoid being injected with fakes.
