Why did my forehead swell after sun and sea exposure?

Question

Hello doctor,

After being out in the sun and sea, my forehead became swollen. I went to the emergency room yesterday and received two IV fluids, one of which contained Cortisone. The swelling in my forehead went down, but I have just noticed that the area between my eyes and nose has started to swell. Now it looks like my eyes are farther apart.

Please help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

I understand how distressing facial swelling can be.

Based on your history, it sounds like you experienced acute photoallergic or sun-induced contact dermatitis, possibly worsened by sea exposure. This may introduce irritants such as salt, algae, or sunscreen ingredients that become reactive under UV (ultraviolet) light.

The initial swelling on your forehead that responded to IV (intravenous) fluids and cortisone suggests an inflammatory or allergic component.

The recent spread of swelling to the area between your eyes and nose could indicate that the inflammation is migrating through the loose connective tissue of the face, which is common in facial reactions due to gravity and lymphatic drainage patterns.

Although this progression is not necessarily dangerous if there are no signs of infection (such as redness, warmth, fever, or pus), any facial swelling, especially near the eyes, should be monitored closely.

I suggest you follow these steps:

Avoid sun exposure entirely until the symptoms fully resolve.
Apply cool compresses.
To soothe the skin, use a bland, hypoallergenic moisturizer (such as one containing ceramides or plain aloe vera gel).
Avoid all cosmetics, sunscreens, and facial products unless specifically prescribed.
If you have not already, an antihistamine like Cetirizine may help reduce residual inflammation, if tolerated. Consult your specialist doctor, discuss with them, and take the medicines with their consent.

If the swelling worsens, begins to involve the eyelids, causes visual changes, or if you develop pain, you should return to the ER (emergency room) or consult a dermatologist immediately to rule out angioedema, cellulitis, or a delayed allergic reaction.

Once this episode fully resolves, allergy patch testing and a review of sunscreen ingredients may help identify specific triggers and prevent recurrence.

I hope this helps you.

Thank you.
