Phytophotodermatitis, also known as berloque dermatitis, [1] [2] [3] margarita photodermatitis, [4] [5] lime disease [6] or lime phytodermatitis [6] is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent (such as lime juice) followed by exposure to ultraviolet A (UV-A) light (from the sun, for instance).
Poikiloderma is a skin condition that consists of areas of hypopigmentation, hyperpigmentation, telangiectasias and atrophy. Poikiloderma of Civatte is most frequently seen on the chest or the neck, characterized by red colored pigment on the skin that is commonly associated with sun damage. [1]
Some common genetic causes include mutations in the tyrosinase gene or OCA2 gene. [3] [4] As melanin pigments tend to be in the skin, eye, and hair, these are the commonly affected areas in those with hypopigmentation. [2] Hypopigmentation is common and approximately one in twenty have at least one hypopigmented macule.
Staying under the sun will worsen burns and cause itchiness, Lazar says. To treat burns, he recommends taking an anti-inflammatory medication like Aspirin. Then cool down the burn by applying an ...
Repeated sun exposure can lead to sun damage (one sign is uneven skin tone) and degrade the skin’s elasticity, causing wrinkles. This is because UV rays affect the self-renewing skin cells that ...
Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure.
"Repeated heat exposure damages superficial blood vessels leading to hemosiderin deposition hyperpigmentation, when excess melanin is released." This, he explains, is what causes the discoloration.
Hyperpigmentation results from an increase in melanin synthesis, which is mostly brought on by sun exposure, dermatological disorders, hormones, aging, genetic factors, skin injuries or inflammation, and acne. Sun exposure, which greatly increases the synthesis of melanin, is the most common cause of hyperpigmentation. [4]
