Ablative fractional laser aftercare

This information is for patients who have had fractional laser treatment at Spot Check Clinic. Fractional laser creates many small treatment zones in the skin to treat solar keratoses, sun damage and improve skin quality. Healing involves a short period of redness and crusting.

What to expect as the skin heals

• First 24–48 hours — redness, warmth and possible pinpoint bleeding at the treated site. The skin may feel hot, similar to a sunburn.
• Days 3–7 — small crusts form, often in a grid-like pattern. The skin may feel dry and rough, like sandpaper. This is a normal part of the healing process.
• 1–2 weeks — crusts naturally separate and the skin begins to settle. Pinkness remains.
• Several weeks onwards — redness gradually fades and skin quality improves. By 4–6 weeks the response to treatment can be properly assessed.

What is normal after fractional laser

• Redness and swelling, particularly in the first 48 hours
• A grid-like pattern of tiny brown or red dots
• Fine crusting or a rough, sandpaper-like texture
• Mild itching as the skin surface regenerates
• Swelling around the eyes if the face was treated

Contact the clinic if you notice

• Pain or redness that continues to increase after 48 hours
• Spreading redness beyond the treated area
• Thick or honey-coloured discharge
• Blistering or signs of a cold sore outbreak
• Fever or feeling generally unwell

Managing your recovery

First 48 hours

If the area feels hot or uncomfortable, apply a cool compress for 10–15 minutes at a time. Avoid strenuous exercise, saunas and hot environments for 48 hours.

Use the wound-care product provided or recommended for you. Epicyn hydrogel is a gel, not a spray; follow your clinician’s instructions for the specific product.

Paracetamol can be used for discomfort if needed.

Cold sores

If the treatment was on your face and you have a history of cold sores, your doctor may have prescribed antiviral medication such as famciclovir. Continue taking it for 3 days after your procedure if instructed.

Skin care

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

Apply a bland moisturiser or healing balm such as La Roche-Posay Cicaplast regularly to keep the skin hydrated and prevent crusts from becoming tight or itchy. Continue daily moisturising for the first 4 weeks.

Do not pick at or peel crusts — this increases the risk of scarring.

Avoid active or irritating skin care products for 1–2 weeks after treatment:

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

LED light therapy

LED light therapy may be recommended after fractional laser to support recovery. Benefits vary; your clinician will advise whether sessions are worthwhile and when to attend.

Sun protection

Healing skin is more vulnerable to UV damage and pigmentation changes. Avoid direct sunlight on the treated area for at least 2 weeks. Apply broad-spectrum SPF 50+ daily once the skin surface has settled. Wear a broad-brimmed hat when outside.

Your follow-up appointment

A review is usually scheduled 4–6 weeks after treatment to assess the response — including clearance of solar keratoses — and determine whether further sessions are required. The need for further sessions depends on the condition, treatment settings and response.

To book your next session, please contact the clinic.

Long-term skin health

If you have had fractional laser for significant sun damage, you have an elevated risk of further solar damage and skin cancers in future. Keep sun-exposed areas protected by sunscreen, clothing or shade. A full body skin check annually is recommended to look for skin cancers and new areas of sun damage.

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