What is solar lentiginosis?

Solar lentiginosis是一种常见的皮肤病，大多出现在40岁以上的白人。该病症涉及浅褐色至皮肤上的浅棕色斑点，称为太阳赛，肝斑或年龄斑点。年龄斑点是平坦的，通常是皮肤的椭圆形，具有增加色素沉着。换句话说，它们比周围的皮肤更暗。它们可能是棕色，黑色或灰色。

They’re most common on parts of the body that get regular sun exposure. This includes the:

  • face
  • hands
  • 武器
  • 脚顶
  • shoulders
  • 背部上方

Although they can sometimes look like cancerous growths, age spots are harmless. However, treatments such as skin lightening or removal can be used for cosmetic purposes. The best way to prevent age spots is to avoid the sun and wear sunscreen.

Ultraviolet (UV) light from the sun is the primary cause of age spots. The pigment that gives your skin color is called melanin. UV light speeds up the production of melanin, which results in darker skin, or a tan. After years of exposure to UV light, melanin builds up in certain areas and is produced in high concentrations. This results in age spots.

来自鞣制床的UV光来自人工来源，而是与太阳的自然光没有不同。衰老的过程，无论紫外线暴露如何，也增加了黑色素的产生并导致年龄斑点。

由于遗传化妆，有些人可能更容易形成年龄斑点。例如，如果您有公平的皮肤和金色的头发，您可能更有可能开发Lentigines。

太阳能小痣是无害的。一些皮肤病s that may resemble lentigines may be more serious, such as:

  • moles
  • melanoma, which is a malignant skin cancer
  • keratosis, which is a noncancerous skin growth
  • lentigo maligna, which is a type of skin cancer

See your doctor if you notice any of the following characteristics in your skin spots:

  • very dark pigmentation
  • an increase in size over a short period
  • 一个不规则的边界
  • 瘙痒，压痛，出血或发红
  • 颜色的组合

您的皮肤科医生将从视觉检查开始，以诊断太阳能叶绿素，排除任何其他皮肤状况。皮肤科医生通常可以通过看着它们来识别年龄斑点。

如果您或您的医生有任何疑虑或相信您的皮肤上的斑点可能有不同的原因，您可能需要皮肤活组织检查。这意味着您的医生将从有问题的地区采取小样本。你会收到当地麻醉剂，你的医生将切掉一小块皮肤。他们将样本发送给实验室进行检查，以确定您是否有太阳能母霉素以外的条件。

因为年龄斑是无害的，但治疗不是必需的。然而，许多人选择治疗化妆品原因的年龄斑点。局部药物通常不如物理程序效果效果，但后者会产生不必要的副作用。

治疗s include the following:

  • 您的皮肤科医生可以开漂白霜以减轻时代斑点。这些通常与类固醇和类含油霜一起使用。在一起，这些药物随着时间的推移可以减轻你的皮肤。
  • Cryotherapy involves using liquid nitrogen to freeze the skin of the age spot. This can destroy the melanin that is producing the dark color. There is a small risk of scarring with cryotherapy.
  • Dermabrasion涉及使用旋转刷子来擦洗皮肤并去除其表面层。您可能会从此程序中遇到发红和刀片。

激光治疗

使用激光器时代斑点可以破坏产生黑色素的细胞。这种治疗需要几次访问，并将导致年龄的斑点在几周或几个月的过程中褪色。如果正确完成，激光疗法没有副作用。这是最昂贵的去除技术。

Chemical peel

A chemical peel involves applying acid to your skin to dissolve its outer layers. New skin forms where the layers were destroyed. You need to have the treatment several times to see results. Irritation from it can be mild to severe. You should protect your skin from the sun immediately after the treatment.

The best way to prevent the formation of age spots is to avoid exposure to the sun and tanning beds. Use sunscreen that provides protection from both types of UV light, UVA and UVB. Cover yourself with a hat, sunglasses, and clothing when you’re in the sun.

Solar lentiginosis is a harmless skin condition that often occurs with aging. No treatment is necessary from a health perspective, but you may want to treat it for cosmetic reasons. If so, various medications and therapies are available. You can discuss them with your doctor. You can help prevent age spots by always using sunscreen and covering yourself with a hat, sunglasses, and clothing when you’re in the sun.
