The essentials: Angular cheilitis is that painful cracking at the corners of your mouth — red, raw, sometimes crusty, always annoying. In North Port, the combination of high humidity, air conditioning running nine months a year, and hard well water creates the perfect storm for it. The humidity keeps your skin damp, the AC dries it out, and the mineral-heavy water messes with your skin barrier. Left alone, it gets infected with yeast or bacteria, turns chronic, and what started as a minor nuisance becomes something your dentist notices and asks about.
1 Start with the right antifungal cream
Most angular cheilitis in adults is driven by Candida — the same yeast that causes other fungal infections. Clotrimazole 1% cream is the standard fix, available over the counter, and it works on the most common cause without a prescription. Apply a thin layer to the corners of your mouth twice a day after meals. I cleared mine in four days doing exactly this.
Start Here
Lotrimin AF Antifungal Cream Clotrimazole 1%
$9.97
★★★★☆ 4.7 (8,000+ reviews)
"Clotrimazole 1% is the active ingredient dermatologists reach for first, and this is the most reviewed version of it on Amazon."
⚠️ Avoid: Skip the generic lip balm approach — ChapStick and Vaseline trap moisture at the corner crease and can actually feed yeast growth, making it worse.

2 Seal the corner after the antifungal dries
Once the antifungal is working, the cracked skin still needs a barrier so saliva stops pooling in the corners overnight. A zinc oxide paste does this without feeding the infection. It is the same ingredient in diaper rash cream for the same reason — it blocks moisture while letting skin heal. Apply a tiny amount over the treated area at bedtime.
Step 1
Desitin Maximum Strength Baby Diaper Rash Cream 40% Zinc Oxide
$7.49
★★★★☆ 4.8 (40,000+ reviews)
"40% zinc oxide is the highest concentration you can buy without a prescription, and the thick paste stays put overnight."

3 Fix the water you are washing your face with
North Port well water pulls from the Myakka aquifer and runs high in iron, sulfur, and minerals. Hard water disrupts your skin's natural pH and strips the barrier that keeps cracking from coming back. A shower filter will not fix your whole house, but it takes the worst of it off your face every morning. This is the reason people clear it up and then it comes back two weeks later.
The Fix
AquaBliss High Output Universal Shower Filter SF100
$29.99
★★★★☆ 4.4 (22,000+ reviews)
"It installs in five minutes with no tools, fits any showerhead, and the multi-stage filter actually addresses chlorine, iron, and sulfur — the three things in North Port water that irritate skin."
⚠️ Avoid: Do not buy a shower filter that only advertises chlorine removal — Charlotte County well water problems go beyond chlorine, and a single-stage carbon filter will not move the needle on iron or sulfur.

4 Add back what the AC pulls out of the air
Running central air in North Port from April through November means indoor humidity often drops into the 30s — desert-dry air that cracks lips and corners the same way winter does up north. A small ultrasonic humidifier in the bedroom keeps your lips from drying out while you sleep and gives the healing skin the moisture it needs. Keep it between 45 and 55 percent.
Game Changer
Levoit Classic 300S Ultrasonic Smart Humidifier
$59.99
★★★★☆ 4.6 (12,000+ reviews)
"The built-in humidity sensor actually shuts off when it hits your target level, so you are not accidentally creating a mold situation in a Florida bedroom."
⚠️ Avoid: Skip any humidifier without an auto-shutoff humidity sensor — in North Port, outdoor air can push indoor humidity up fast overnight, and a dumb humidifier running all night is a mold starter kit.

5 Close the nutritional gap that keeps it coming back
Chronic angular cheilitis that comes back every few weeks is often a B2 or B3 deficiency, especially in older adults whose absorption decreases with age. A B-complex covers riboflavin, niacin, and B12 together so you are not guessing which one you are short on. This is not a substitute for the antifungal — it is what you take after you clear it so it stays gone.
Don't Skip
Thorne Basic B Complex B-Vitamin Supplement
$24.00
★★★★☆ 4.7 (5,000+ reviews)
"Thorne uses the activated forms of B vitamins, which are better absorbed by older adults and people with common MTHFR gene variants — and that describes a lot of the 65-plus population in North Port."

DIY total: $131 total for everything on this page
vs. professional: Dermatology or urgent care visit in Charlotte County typically runs $150-$250 out of pocket for an uninsured visit, plus $40-$80 for prescription antifungal if they write one.
You save: Up to $200 saved versus going the clinic route for something a $10 cream usually handles.
Four days of antifungal cream, a shower filter for that Myakka well water, and a humidifier to counteract the AC — that is the whole protocol.
