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.
