Hello,
Yellow stains: Usually due to sweat mixing with deodorant/antiperspirant ingredients (especially aluminum) or bacteria on fabric. It’s not due to poor hygiene.
Sweating in all seasons suggests axillary hyperhidrosis (overactive sweat glands), which is common and treatable.
Shaving
Daily shaving is not necessary and may irritate skin → more sweating and odor.
Shave once a week or when hair grows, keep clean, and avoid harsh friction.
🛑Use a clinical-strength antiperspirant, not just deodorant.
Best option: Aluminum chloride hexahydrate 20% (apply at night to dry skin, wash off in morning).
For irritation: use moisturizer, reduce frequency, or consult a doctor.
Helpful habits Bathe daily, dry armpits well. Wear breathable cotton clothes, change sweaty clothes quickly. Avoid spicy foods, caffeine if they worsen sweating.
If sweating is excessive, affects daily life, or has started recently, consult a dermatologist in person
I trust this helps Thank you
Excessive sweating, or hyperhidrosis, can understandably be frustrating and does affect daily comfort and confidence. Shaving regularly is fine but it won’t directly resolve the sweating or the yellow stains, which are common due to a reaction between sweat and fabric or deodorants. A good start would be using a strong antiperspirant; those containing aluminum chloride are typically effective. Apply it at night on dry skin when sweat glands are less active, allowing it time to effectively block sweat glands. During the day, a few reapplications can sustain its effect, though be cautious not to irritate the skin. If antiperspirants aren’t helping sufficiently, consider consulting a doctor about prescription-strength options or treatments like iontophoresis or Botox injections, both of which can significantly reduce sweating by targeting sweat glands specifically. Also, wearing loose-fitting clothes made from breathable fabrics like cotton can aid in reducing perspiration and its visibility. Sometimes excessive sweating may be linked to other factors like stress, diet or medical issues such as thyroid problems. If you notice unusual symptoms like weight changes or persistent fatigue, however, seek evaluation for underlying conditions that can be affecting sweat levels. Finally, regarding shaving, ensure your technique is gentle to avoid irritation which can worsen perspiration issues. Shaving every day isn’t necessary; allow time for any irritation to settle between shaves and, consider using soothing, alcohol-free products post-shave to calm the skin.
Aluminum Chloride Hexahydrate 20% solution (e.g., Drysol)
Apply at night, 2–3 times per week
Wash off in the morning
Apply on completely dry skin only
Hello Zain I understand how frustrating and embarrassing excessive underarm sweating (also called axillary hyperhidrosis) can be, especially when it affects your confidence at school. Let’s break down your concerns and what you can do:
1. Shaving and Hygiene - Shaving every day isn’t necessary and can actually irritate the skin, making sweating and odor worse. Shaving 1–2 times a week is usually enough, or as needed to keep hair short. - Focus on gentle cleansing with a mild soap and pat dry—avoid harsh scrubbing.
2. Managing Excessive Sweating - Use a clinical-strength antiperspirant (not just deodorant). Look for products with aluminium chloride hexahydrate, which are more effective for sweating. Apply at night before bed, when sweat glands are less active, and again in the morning if needed. - Wear loose, breathable cotton clothes and change shirts if they get damp. - Try to stay cool and manage stress, as anxiety can make sweating worse.
3. Home Remedies - You can try dusting a little baking soda or cornstarch under your arms to absorb sweat. - Some people find wiping with diluted apple cider vinegar at night helps, but do a patch test first to avoid irritation.
4. When to See a Doctor - If sweating is severe, not controlled by antiperspirants, or affecting your daily life, a dermatologist can offer treatments like prescription antiperspirants, oral medicines, or even procedures like Botox injections for underarm sweating.
Thank you
Apply moisturizer in that area if condition not ready kindly msg
Hello Muhammad Zain, I understand your worry and here is my advise-
1. About Shaving- Shaving daily is NOT required. Shave once every 5–7 days. Daily shaving can irritate skin, worsen sweating, and cause discoloration. Trim or shave at night, not just before school.
2. You should get these tests done to rule out of this is happening due to any disease - CBC, FT3 FT4 TSH, Fasting Blood Glucose, HbA1C. Review with reports.
3. Use Sweatnil Antiperspirant Roll-On (night use). Do NOT apply in the morning. Mild itching initially is common. Apply on completely dry skin. Use 3 nights in a row, then once weekly.
4. Morning Routine- Wash underarms with plain water or mild soap. Apply a light deodorant only if needed (no heavy perfumes)
5. Reduce Yellow Stains- Avoid deodorants containing aluminum + fragrance together in daytime. Wear cotton undershirt/vest. Avoid tight synthetic fabrics. Wash white shirts immediately after sweating.
6. Physically Consult a Physician if - Sweating soaking clothes daily. Associated weight loss, palpitations, tremors. No improvement after 1 month of antiperspirant.
