Purpura/superficial bruises
Home • Dermatology • Common Skin Conditions • Purpura/superficial bruisesAbout
Actinic purpura, also known as senile purpura, is a condition characterized by the development of easy bruising, particularly on sun-exposed areas of the skin such as the forearms and back of the hands. This condition is most commonly seen in older adults due to the skin’s natural thinning with age.
AboutSymptoms
- Purplish or reddish bruises that appear spontaneously.
- Bruises that are typically found on sun-exposed areas.
- Skin that appears thin and may be more transparent, showing the small blood vessels beneath.
Causes
The primary cause of actinic purpura is long-term sun exposure which damages the structural collagen that supports the blood vessels within the skin. As collagen degrades over time, the skin becomes less able to support the vessels, making them more prone to breaking under minor stress. Factors that exacerbate this condition include:
- Chronic sun exposure.
- Aging skin.
- Use of certain medications like corticosteroids and blood thinners
Treatments
Treatment for actinic purpura focuses on prevention and managing the appearance of the bruises:
- Protective Clothing: Wearing long sleeves and pants can help protect the skin from further sun damage. Arm Chaps are available online and are an excellent option to protect the arms during house and yard work.
- Sunscreen: Applying broad-spectrum sunscreen to exposed skin areas can reduce additional sun damage.
- Topical Treatments: Topical treatments for actinic purpura primarily aim to strengthen the skin and improve its appearance. Here’s an overview of the topical options commonly considered for managing this condition:
- Topical Retinoids – Topical retinoids can be used to help rebuild collagen, thereby improving the skin’s overall texture and elasticity. Retinoids stimulate the production of new collagen fibers in the dermis, which may help reduce the susceptibility of the skin to bruising. However, they must be used consistently over a period of time to see improvement.
- Vitamin K Creams – Some evidence suggests that topical Vitamin K may help reduce the severity of bruising. Vitamin K is thought to aid in the process of blood clotting and repairing blood vessels, which might be beneficial for those with actinic purpura. These creams are available over the counter and can be applied directly to the bruised areas.
- Arnica – Arnica is a natural remedy often used to treat bruises. Available as a cream or gel, arnica can be applied topically to help reduce swelling and speed up the healing of bruises. While widely used, the effectiveness of arnica for actinic purpura is anecdotal, and it might not have the same impact as more targeted treatments.
- Moisturizers and Emollients – Keeping the skin well-moisturized is crucial for maintaining its integrity and protective barrier. Moisturizers, particularly those containing lactic acid or urea, can help hydrate the skin and make it less prone to tearing and bruising. These products are generally supportive and can be used in conjunction with other treatments.
