Years of sun exposure can leave lasting marks on the skin – from stubborn sun spots to fine lines and an uneven texture that no skincare routine seems to fix.
This case study looks at how a combined DEKA Q-switch and full-face CO2 fractional laser treatment helped one patient achieve clearer, smoother, and more youthful-looking skin, with visible results in days rather than months.
Sun spots, fine lines and uneven skin texture
A 51-year-old female patient came to clinic with sun-induced hyperpigmentation, specifically sun spots, as well as fine lines and an uneven skin texture. She was looking to rejuvenate her skin and achieve a clearer, smoother, more youthful complexion. Her medical history had no contraindications for laser therapy, though her lifestyle included significant sun exposure in her earlier years – a key contributor to her current skin concerns.
Assesing hyperpigmentation
On clinical examination, sun spots were observed predominantly on the cheeks, forehead, and upper lip. Fine lines were most noticeable around the periocular and perioral areas, while the overall skin texture appeared slightly rough and lacked uniformity. Following a comprehensive evaluation, targeted laser treatments were identified as the most effective approach for addressing these concerns.
Treatment approach: A combined laser protocool
The patient underwent a two-pronged laser treatment strategy designed to address both hyperpigmentation and skin texture irregularities.
1. DEKA Q-Switch laser treatment for sun spots
Objective: The Q-switch laser was chosen for its precision in targeting and breaking down the melanin deposits responsible for sun spots. This laser emits high-intensity pulses that fragment pigmented lesions without damaging surrounding skin tissue.
Procedure details: The Q-switch laser was used for one session lasting 10–15 minutes at a wavelength of 532 nanometres. It was performed ahead of the CO2 laser to specifically target the patient's sun spots. This laser treats sun spots in a single session, as well as addressing generalised pigmentation.
Post-procedure care: The patient was advised to avoid direct sun exposure and use a broad-spectrum sunscreen. Mild redness was anticipated and managed with a soothing topical cream.
2. CO2 fractional laser treatment for texture and fine lines
Objective: The fractional CO2 laser was selected to improve skin texture and reduce the appearance of fine lines by promoting collagen production and skin resurfacing. Fractional technology creates micro-injuries that trigger the skin's natural healing process, enhancing tissue regeneration.
Procedure details: Following the Q-switch laser treatment, Dr Injibar used the CO2 laser across the whole face to resurface the skin, address pigmentation, and improve overall skin texture and tone. This treatment takes approximately 35 minutes, which also allows time for numbing.
Post-procedure care: Redness typically lasts five to seven days post-treatment. By day two, the skin develops a tan-like appearance and yellowish crust, which should be wiped with a vinegar solution twice daily. Skin flaking begins around five to seven days on the face and neck. Some swelling and a sunburn-like feeling may occur for three to four days but are normal unless accompanied by pain or fever.
Postcare instructions included:
- Staying out of direct sunlight
- Cleansing with a vinegar solution
- Applying a prescribed topical antibiotic for four days
- Using Aquaphor or Vaseline frequently for hydration
- Avoiding scrubbing the treated area
- Using SPF 30+ sunscreen daily
- Avoiding picking scabs
- Refraining from heat exposure and vigorous exercise
- Staying hydrated and sleeping with an elevated pillow on the first day to reduce swelling
How does combined laser therapy treats hyperpigmentation?
Sun spots: The DEKA Q-switch laser treatment proved highly effective in resolving hyperpigmentation. By day five post-treatment, a marked lightening of sun spots was visible. By the final post-treatment assessment, the sun spots had completely faded, leaving a uniform skin tone.
Fine lines and skin texture: The CO2 fractional laser treatment delivered significant improvements in skin smoothness and a reduction in fine lines. By day six post-treatment, the skin appeared fresher, with visible improvement in texture and reduced fine lines around the eyes and mouth. At the final post-treatment evaluation, the patient's skin showed a substantial increase in smoothness, firmness, and overall radiance.
The patient shared: "After summer, I have lots of pigmentation and uneven skin tone due to being in the sun. I am looking forward to having my laser treatment at Dermasurge and restoring a more flawless complexion. I have had multiple treatments with Dr Injibar over the years and they have always been amazing. She makes me feel very comfortable."
The combined use of DEKA Q-switch and CO2 fractional lasers provided a comprehensive treatment approach, effectively targeting both pigmentation and textural concerns in a single treatment plan. The nonablative nature of the DEKA Q-switch ensured safe and efficient removal of hyperpigmentation, while the fractional CO2 laser stimulated deep skin rejuvenation.
This dual-modality approach highlights the importance of tailoring treatment plans to address multiple skin concerns in ageing skin. By targeting different skin layers – the epidermis for pigmentation and the dermis for texture and fine lines – optimal outcomes were achieved.
