Comparative Effectiveness of Long-Pulsed 1064-nm Nd:YAG and Fractional CO₂ Laser in Skin Rejuvenation
Sponsor: Universitas Padjadjaran
Summary
Skin rejuvenation is an effort to improve skin condition from the signs of skin aging. Skin aging is a complex biological process influenced by intrinsic and extrinsic factors, leading to changes in the epidermis and dermis, including decreased collagen characterized by dermal thinning, as well as alterations in skin appearance such as laxity and wrinkles. Laser therapy is one of the treatment modalities for skin rejuvenation, aiming to induce neocollagenesis and collagen remodeling, resulting in dermal thickening and improvement in skin appearance. Fractional CO₂ laser is an ablative laser considered the gold standard therapy for skin rejuvenation, whereas Long Pulsed (LP) Nd:YAG 1064 nm is a nonablative laser that is also used for skin rejuvenation. To date, there have been no studies evaluating the comparative effectiveness between fractional CO₂ laser and LP Nd:YAG 1064 nm for skin rejuvenation. Therefore, research comparing the effectiveness of fractional CO₂ laser and LP Nd:YAG 1064 nm for skin rejuvenation is needed, assessed based on dermal thickness, skin elasticity, wrinkles, and Global Aesthetic Improvement Scale scores.

Fractional CO₂ laser
Fractional CO₂ laser was applied to one randomized side of the face in a split-face design for skin rejuvenation. Treatments were performed three times at one-month intervals. The laser delivers fractional ablative microthermal zones to stimulate dermal remodeling and collagen production. Treatment parameters were adjusted according to skin type and clinical indication.
Long-pulsed 1064-nm Nd:YAG laser
Long-pulsed 1064-nm Nd:YAG laser was applied to the contralateral randomized side of the face in a split-face design for skin rejuvenation. Treatments were performed three times at one-month intervals. The laser delivers non-ablative dermal heating to stimulate collagen remodeling and improve skin texture and elasticity.
