How to care for your skin after HA injection

Having smooth, hydrated skin is a desire for many. Among modern beauty methods, hyaluronic acid (HA) injections are increasingly popular due to their ability to deeply moisturize, restore skin structure, and quickly improve signs of aging. However, to achieve optimal results and avoid complications, post-HA injection skincare plays a crucial role. So, what exactly is HA injection? What should you avoid after injection, and how should you care for your skin to ensure the best recovery? Let’s explore the details in the article below from HBIO Clinic.

What is HA injection?

HA (Hyaluronic Acid) injection is a method of directly introducing hyaluronic acid, a naturally occurring water-retaining substance in the body, into the dermis of the skin through micro-injection (mesotherapy) or deep injection (filler) techniques, with the aim of deep moisturizing, plumping, improving skin structure, and reducing wrinkles.

This method is commonly applied in the following treatments:

• HA skin booster injections
• Meso moisturizing injections
• 5-point BAP injections (Profhilo, Ejal40…)
• HA injections in the lips, eyes, smile lines, forehead…

Depending on the type of HA used (free HA, cross-linked HA, or HA combined with peptides/amino acids), the purpose of the injection, and the doctor’s technique, the effects can last from 4 months to over 1 year.

What are the effects of HA injections on the skin?

HA (Hyaluronic Acid) injections offer many benefits for the skin, including:

Deep hydration from within

When injected into the skin, Hyaluronic Acid (HA) attracts and retains water in the dermis – a layer that topical cosmetics cannot reach. As a result, your skin will:

• Be noticeably plumper after just 24–48 hours
• Reduce dryness, cracking, and peeling, especially during dry seasons
• Have a natural, subtle glow like Korean “glass skin”.

Filling in shallow wrinkles

Micro-injection techniques introduce HA into areas of skin experiencing slight volume loss, such as:

• Smile lines, corners of the mouth
• Fine wrinkles around the eyes, crow’s feet
• Areas of skin beginning to sag

Results: Gentle filling without altering facial expression like deep fillers.

Increased elasticity and firmness

HA is a connective tissue in the skin, so when properly administered, it will:

• Stimulate the skin’s natural production of collagen and elastin
• Thicken the skin, reducing the appearance of “paper skin”
• Suitable for women over 25 or those with early signs of aging

Brighten and even out skin tone

Some injectable HA (such as Ejal 40, Profhilo, Juvelook…) also contain: Peptides, amines, glutathione, vitamin C…

These substances help improve skin tone, fade dark spots, and make the skin naturally bright and healthy, not pale.

Skin Repair After Acne or Procedures

HA injections are also used for:

• Skin recovery after microneedling, laser treatments, and chemical peels
• Soothing thin, weak, and easily irritated skin areas
• Supporting the filling of newly formed shallow acne scars, resulting in smoother skin after a few injections

How to care for your skin after HA injections

Proper skin care after HA injections is crucial for faster recovery and optimal results. Below are detailed instructions:

Gently apply cold compresses for the first 24 hours

• Use a clean towel to wrap ice cubes or a cold gel pack, and apply it to the injection area for about 5-10 minutes each time, every 1-2 hours to reduce swelling and bruising.
• Do not apply ice directly to the skin to avoid frostbite.

Keep the injection site clean and gentle

• Wait 6–8 hours before washing your face, using warm water and a gentle cleanser, avoiding harsh scrubbing.
• Avoid using exfoliating products or those containing strong acids (AHA, BHA, retinol) for at least 3–5 days.

Do not apply makeup for the first 24 hours, and do not squeeze, press, or massage the injection site

• To avoid bacteria and irritation, do not use cosmetics or moisturizers immediately after HA injection.
• Avoid mechanical manipulation of the skin in the injection area for at least 1 week to allow the HA to stabilize and not shift position.

Protect yourself from the sun carefully

• Use broad-spectrum sunscreen SPF 30+ daily, reapplying every 2–3 hours if outdoors.
• Limit direct sun exposure for at least 7 days.
• Combine this with protection using a wide-brimmed hat, face mask, or sunglasses.

Avoid high temperatures and strenuous activity

• Do not use steam rooms, hot baths, saunas, or engage in strenuous exercise for the first 2–3 days as this can easily cause swelling and uneven distribution of HA.
• Keep the skin cool and avoid hot compresses.

Drink plenty of water and eat a healthy diet

• Drink at least 2 liters of water daily to help HA maximize its moisturizing effects.
• Eat plenty of green vegetables and fruits rich in vitamins C and E to support skin regeneration.
• Limit alcohol, fried foods, and sugary foods as they reduce the effectiveness of HA.

Monitor for any unusual symptoms

• Mild swelling and minor bruising are normal and will disappear within a few days.
• If you experience significant pain, lumps, pus formation, or signs of infection at the injection site, contact your doctor immediately.

In short, proper skin care after HA injection is key to maintaining plump, healthy skin and prolonging the effectiveness of the treatment. Following aftercare instructions not only helps your skin recover quickly but also minimizes the risk of unwanted complications.
