micro-crustacean the BC was non-toxic, while the BC degraded by CSS had a toxicity of LC = 397.35 μg/mL. In Wistar rats, females treated with BC degraded by CSS (BCCSS) showed whitish liverspots, alterations in liver weight and in bilirubin and alkaline phosphatase levels, and decrease in the number of leukocytes associated with atypical lymphocytosis. In male rats, there was an increase

: 10.1016/j.jaad.2017.09.053 Lentigines Lentigines (singular: lentigo) are flat, tan to brown, oval macules. They are commonly due to chronic sun exposure (solar lentigines; sometimes called liverspots but are not related to hepatic dysfunction) and occur most frequently on the face and back of the hands. They typically first appear during middle age and increase in number with age. Although
Topical tretinoin (retinoic acid) treatment for liverspots associated with photodamage. The hyperpigmented lesions commonly called liverspots distress patients, in part because such lesions are associated with aging. We investigated their treatment with topical 0.1 percent tretinoin (retinoic acid). Fifty-eight patients completed a 10-month randomized, double-blind study in which they applied both clinical and microscopical manifestations of liverspots; these lesions do not return for at least six months after therapy is discontinued.
Topical tretinoin (retinoic acid) improves melasma. A vehicle-controlled, clinical trial. Melasma is a common disorder of cutaneous hyperpigmentation predominantly affecting the faces of women. Little is known about the aetiology of melasma, and treatment is frequently disappointing. Topical tretinoin is of benefit in treating other forms of hyperpigmentation, for example liverspots, and we
What is the origin of the so-called "brown spots" seen on the skin of elderly people, and have they any clinical significance? We believe you are referring to liverspots or a type of lentigo. For further information eMedicine has a chapter on this topic [1]. This discusses the different types of lentigo and it would appear that the type of lentigo you’re interested in is solar lentigo (or senile lentigo). This states the following, which seems pertinent to the question:“In America, solar lentigines are observed in as many as 90% of whites older than 60 years and in 20% of whites younger than 35 years. ““Solar lentigo (eg, actinic lentigo, senile lentigo, sun spot, liverspot) is the most common benign sun-induced lesion that occurs in sun-exposed areas
skin discolorations caused by hormones. These hormonal changes are usually the result of pregnancy, birth control pills or estrogen replacement therapy. * Solar lentigo, also known as "liverspots" or "senile freckles", refers to darkened spots on the skin caused by aging and the sun. These spots are quite common in adults with a long history of unprotected sun exposure.Aside from sun exposure and hormones, hyperpigmentation can be caused by skin damage, such as remnants of blemishes, wounds or rashes.[93] This is especially true for those with darker skin tones.The most typical cause of darkened areas of skin, brown spots or areas of discoloration is unprotected sun exposure. Once incorrectly referred to as liverspots, these pigment problems are not connected with the liver.On lighter to medium
establishes ultraviolet radiation, especially the non-ionizing medium wave UVB, as the cause of most non-melanoma skin cancers, which are the most common forms of cancer in the world.[3] UV rays can also cause wrinkles, liverspots, moles, and freckles. In addition to sunlight, other sources include tanning beds, and bright desk lights. Damage is cumulative over one's lifetime, so that permanent effects may
or melanoma has been suggested.[76] Some studies indicate no increased risk of melanoma in the long term.[77] Data are inconclusive with respect to nonmelanoma skin cancer risk, but support the idea that the therapy is associated with an increased risk of benign forms of sun-induced skin damage such as, but not limited to, actinic elastosis or liverspots.[77] Dead Sea balneotherapy is also effective
visible effects of skin photodamage are fine lines, skin sagging, skin roughness, liverspots and also the appearance of red patches made up of thin red vessels (called telangiectasia).More and more people are presenting to doctors with concerns about skin photodamage and the demand for corrective procedures is increasing.Metvix® photodynamic therapy (Metvix® PDT) is a procedure currently marketed

At Baseline, participants rated the facial parameters using a 10-point scale ranging from 1 (Not noticeable) to 10 (Very noticeable). At Week 12 and 24, assessment was performed relative to Baseline
