Laser aftercare (non-ablative)

This information is for patients who have had non-ablative laser treatment at Spot Check Clinic. Non-ablative laser treats pigmentation, redness and skin tone without breaking the skin surface.

What to expect as the skin heals

• First 24–48 hours — the skin will feel warm and appear red, similar to a mild sunburn. Some mild swelling is common, particularly around the eyes.
• Days 3–7 — pigmented spots will darken and may feel slightly dry or rough. This is sometimes called the “coffee grounds” effect. The pigment will naturally flake off or fade — do not scrub or pick the area.
• Weeks 1–4 — blood vessels may appear darker or bruised before fading. The skin gradually becomes clearer and more even in tone.
• 4–6 weeks — your doctor or nurse will assess how well the treatment has worked and determine whether further sessions are required.

What is normal after non-ablative laser

• Redness and warmth for 24–48 hours
• Darkening of pigmented spots
• Mild swelling or puffiness
• A hive-like reaction in some patients
• Slight skin dryness or texture change as pigment flakes away

Contact the clinic if you notice

• Blistering or broken skin
• Pain or redness that continues to increase after 48 hours
• Significant swelling that does not settle with cool compresses
• Fever or feeling generally unwell

Managing your skin

First 24–48 hours

Avoid heavy exercise, saunas and hot showers for 24 hours. If the area feels uncomfortable, apply a cool compress for 10–15 minutes at a time.

If swelling is more pronounced, antihistamines such as Telfast or Claratyne can help. Paracetamol can be used for mild discomfort.

Contact the clinic about a hive-like reaction. A doctor or pharmacist can advise whether a short course of hydrocortisone is appropriate; follow the instructions they give you.

Cold sores

If you have a history of cold sores on or around your lips, laser treatment can trigger an outbreak. If we are aware of this history, preventive antiviral medication will be prescribed before your treatment and for several days after.

Skin care

Cleanse twice daily using a gentle soap-free cleanser such as Cetaphil and lukewarm water. Pat dry gently — do not rub or scrub.

Apply a bland moisturiser or healing balm such as La Roche-Posay Cicaplast to the treated area as needed for comfort. Continue using a moisturiser daily for the first 4 weeks.

Avoid shaving the treated area for 3 days.

Do not use active skin care products until the skin has fully settled:

• Retinoids, tretinoin and Retin-A
• Vitamin C serums
• AHAs, BHAs and exfoliating acids
• Antiseptics and alcohol-based toners
• Vitamin E cream
• Soaps and exfoliants

Sun protection

UV exposure after treatment can reverse results and cause pigmentation changes. Avoid direct sunlight on the treated area for at least 2 weeks. Apply broad-spectrum SPF 50+ daily, even in winter, and reapply at least every 2 hours outdoors and after swimming, sweating or towel drying. Wear a broad-brimmed hat when outside.

Your follow-up appointment

A review is usually scheduled 4–6 weeks after your initial treatment. Most non-ablative laser treatments require a series of sessions for the best result. Your doctor or nurse will assess the skin’s response and adjust settings for subsequent treatments if required.

If you notice a new or changing spot in the future, it is important to have it assessed with a skin cancer check.
