“Remodelling of scars and acne with non-ablative fractional laser 1540”

Speaker: Dr Maria Jose Isarria Marcos. IML Dermatologist.
(Summary)

Acne is a pathology that affects 80% of the female population (14 to 17 years of age) and in 90% of the male population (16 to 19 years). It is a multifactorial pilosebaceous unit disorder:

• Increase in sebaceous secretion
• Hormonal stimulation (androgenetic)
• Hyper-proliferation P. acnes
• Follicular hyper-keratinisation
• Inflammatory response, activation of cytokines

Early diagnosis and treatment are important to prevent scarring caused by acne. There are several treatment options:

Medical:
• Retinoids
• Intralesional corticoids, topical
• Silicone patches
• Other topical or injectable substances
• Surgical
• Punch
• Elliptic excision
• Punch elevation
• Sub-excision

Mechanics:
• Cryosurgery – Electrocoagulation – Radiotherapy
• Chemical peels – Microdermoabrasions – Dermoabrasions.
• Fillers
• Laser, light, other energies
• Ablative: CO2, Er:YAG, Fractional
• Non ablative: 532 nm (KTP), 585 nm (PDL), 1064/1320 nm (Nd:YAG), 1450 nm (Diode), 1540 (Er:glass), fractional.
• IPL, Radiofrequency, Plasma
