Hyaluronic Acid Filler Aftercare: What to Expect, How to Care, and Side Effects

July 17, 2025

Whether you’re enhancing your lips, restoring volume to your cheeks, or smoothing out fine lines, hyaluronic acid fillers are a safe, effective, and non-surgical way to refresh your appearance.

At SKINLAB, we want you to love your results and feel confident every step of the way. This guide will walk you through what to expect after your treatment, how to care for your skin, what side effects are normal, and when to get in touch with us.

✨ What to Expect After Filler Treatment

Immediately after your filler treatment, you may notice:

  • Swelling: This is completely normal and may last up to 3–5 days.
  • Redness and tenderness at the injection sites.
  • Mild bruising, especially in areas with thinner skin like the lips.
  • Firmness or lumpiness in the treated area, which typically softens within 1–2 weeks.
  • Asymmetry: One side may appear slightly more swollen than the other at first—this is part of the healing process.

Don’t worry if the area looks “overfilled” at first. Swelling will settle, and your final results will gradually emerge over 7–14 days.

🧖‍♀️ How to Care for Your Skin After Filler

To minimize discomfort and support the healing process, follow these aftercare tips for the first 24–72 hours:

✅ DO:

  • Apply a cold compress (not ice directly) to reduce swelling.
  • Stay upright for at least 4 hours post-treatment.
  • Sleep with your head elevated the first night to minimize swelling.
  • Take Tylenol (acetaminophen) for discomfort (if needed).
  • Drink plenty of water to help keep your skin hydrated.

❌ AVOID:

  • Touching, massaging, or pressing on the treated area.
  • Strenuous exercise, saunas, hot tubs, or excessive heat for 24–48 hours.
  • Alcohol and blood-thinning medications for at least 24 hours (to reduce bruising).
  • Makeup on or near the treated area for 24 hours.
  • Facial treatments, lasers, or peels for 1–2 weeks.

🩺 Common Side Effects (Expected)

Most side effects are temporary and resolve on their own:

  • Swelling
  • Redness
  • Tenderness or soreness
  • Bruising
  • Mild itching
  • Lumps or firmness, which soften over time

These usually resolve within a few days to a week.

⚠️ Rare Side Effects (Uncommon, but Possible)

While rare, some side effects require monitoring:

  • Prolonged or severe swelling lasting more than 7 days
  • Nodules or firm lumps that don’t soften after 2 weeks
  • Unevenness or asymmetry that doesn’t improve after swelling resolves
  • Discoloration (pale or bluish skin) in or near the injection area
  • Pain that increases over time

🚨 When to Contact SKINLAB

We’re here to support you at every stage. Please contact SKINLAB right away if you experience:

  • Severe pain, especially if it’s increasing or persistent
  • Skin discoloration (especially white, bluish, or blotchy patches)
  • Signs of infection: heat, pus, fever, or redness that spreads
  • Visual disturbances, dizziness, or severe headache

Even if you’re unsure whether something is normal, we’re happy to check in and make sure you’re healing well.

💬 Final Thoughts

Your hyaluronic acid filler treatment is a beautiful step toward refreshed, natural-looking skin. Most people experience only mild side effects and love their final results once swelling subsides.
