Photosensitivity: Types, symptoms & protection tips

Photosensitivity refers to increased sensitivity of the skin or unusual reaction when exposed to ultraviolet (UV) radiation. Some individuals may experience symptoms such as intense redness, irritation, blisters, or rashes even after a brief exposure to sunlight or artificial light sources (e.g., tanning beds). This reaction is known as photosensitivity.

Types of photosensitivity

There are two different types of photosensitivity reactions: photoallergic and phototoxic.

Phototoxic reaction: This is the most common type of photosensitivity reaction, typically occurring when a medication, taken either orally or applied topically, becomes activated after exposure to UV radiation, leading to the appearance of a rash or a sensation similar to sunburn. Certain ingredients found in skincare products can also trigger this reaction. A phototoxic reaction may develop within minutes or hours after exposure and is usually limited to the area of skin that was exposed.

Photoallergic reaction: Less common than phototoxic reactions, photoallergic responses occur when UV rays interact with certain ingredients in medications or skincare products applied directly to the skin. This reaction may be manifested through symptoms such as rashes, red bumps, or even bronchial symptoms, typically appearing one to three days after product application and sun exposure.

Symptoms

The severity of photosensitivity symptoms varies depending on the intensity of the reaction. Common symptoms include:

• Intense skin redness
• Blisters and swelling
• Itching, burning, or tingling sensation
• Dryness and skin peeling
• Hyperpigmentation

Causes and risk factors

Several factors may contribute to the development of photosensitivity:

Medications: Certain widely used medicines, including antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), antidepressants, and acne treatments, can make the skin particularly sensitive to UV radiation.

Medical conditions: Some health conditions, such as autoimmune diseases like systemic lupus erythematosus, can increase the risk of photosensitivity reactions.

Skincare products: Ingredients of various cosmetic products, such as retinol, glycolic acid, benzoyl peroxide, and vitamin C, can heighten the skin’s sensitivity to UV exposure.

Prevention and protection

To minimize the risk of photosensitivity, consider the following precautionary measures:

• Consult your doctor about potential photosensitivity risks associated with any medications you take or health conditions you may have.
• Seek advice from a dermatologist regarding skincare products that could trigger photosensitivity, whether prescribed or not.

• Use a high SPF sunscreen all year round. MACROVITA Sun Protection Face & Body Spray SPF50 with aloe vera, panthenol & olive oil, has a light texture suitable for all skin types. Rejuvenates and hydrates the skin, while preventing photoaging and protecting it from the adverse effects of exposure to radiation of the entire spectrum (UV, IR, BLUE LIGHT). Instantly absorbed without leaving any residue, also ecologically improved based on patented EcoSun Pass® technology. Apply daily before exposure to the sun or blue light. Shake well, spray a sufficient amount onto your hands, and then apply to the exposed areas, avoiding contact with the eyes. Renew frequently, especially after perspiring, swimming, or towel-drying.
• Limit sun exposure, particularly between 11:00 AM and 3:00 PM.
• Avoid artificial tanning processes.
• Wear a hat, sunglasses, and lightweight, long-sleeved, protective clothing to cover exposed skin.

Staying informed through medical professionals (doctors, dermatologists), using proper sun protection, and avoiding photosensitizing substances or practices are key steps to maintaining healthy skin. Enjoy the sun responsibly!
