| 1. External Mechanical Dilator Strips | Temporarily widen the nasal passages by lifting the outer nasal walls. | Flexible adhesive backing with a spring-like polymer or resilient support band. | Wash and dry the nose, remove oils, center the strip across the nasal bridge, and press both ends firmly. | Loosen one corner slowly and peel sideways or downward. Use warm water or a gentle oil-based cleanser if needed. | Often several hours or overnight, according to the product instructions. | May cause redness, itching, or adhesive irritation. Do not apply over cuts, sunburn, eczema, or active dermatitis. |
| 2. Flexible Polymer Dilator Strips | Provides gentler external support for easier nasal airflow. | Soft polymer support element combined with a pressure-sensitive medical adhesive. | Apply to clean, completely dry skin without moisturizer or sunscreen underneath. | Lift the edges gradually; dampen the adhesive before removal if the skin feels pulled. | Commonly used for a few hours or during sleep. | Check the first application after a short period. Repeated use in the same location can increase irritation or adhesive sensitivity. |
| 3. Fabric-Based Nasal Strips | Combines external lifting with a soft, conformable surface. | Woven or nonwoven fabric carrier with an acrylic or rubber-based pressure-sensitive adhesive. | Smooth the strip from the center outward and avoid placing it too close to the nostril openings. | Remove slowly in the direction of hair growth; warm water can reduce pulling. | Usually several hours, depending on adhesion and personal comfort. | Fabric may retain sweat and oil. Discontinue use if burning, swelling, blistering, or persistent redness develops. |
| 4. Transparent Film Strips | Provides discreet external nasal support. | Thin transparent polyurethane or polymer film with a pressure-sensitive adhesive. | Apply only after cleansing and drying the bridge of the nose; press firmly for several seconds. | Peel back slowly from both ends rather than pulling straight upward. | Commonly worn for a few hours or overnight when tolerated. | Occlusive film can trap moisture. Avoid use on broken skin and stop if heat rash or itching occurs. |
| 5. Hypoallergenic Adhesive Strips | Offers external nasal support for users concerned about adhesive sensitivity. | Often uses low-irritant acrylic adhesive and may be latex-free; exact materials vary. | Perform a small patch test on the arm or cheek before the first full application. | Soften the adhesive with warm water and remove gradually without repeated tugging. | Follow the package directions; shorter initial wear is advisable for reactive skin. | “Hypoallergenic” does not mean allergy-proof. Review the ingredient and latex information, and stop use after any reaction. |
| 6. Hydrocolloid Nose Pore Strips | Absorbs fluid and protects individual blemishes or superficial irritated spots. | Hydrocolloid gel-forming particles on an adhesive backing; generally works best on small pimples rather than blackheads. | Clean and dry the area, apply over a small surface blemish, and avoid creams beneath the patch. | Peel from an edge after the patch has turned opaque or loosened; do not forcibly remove it. | Often several hours or overnight, depending on the product instructions. | Not a nasal-airflow dilator. Avoid infected, deeply inflamed, or extensively irritated skin unless advised by a clinician. |
| 7. Charcoal-Infused Pore Strips | Adheres to surface debris and oil in the pore area when removed. | Usually a drying film or fiber strip containing activated charcoal; pore-cleansing performance varies. | Wet the nose only as directed, apply smoothly, and wait until the strip is firm but not painfully tight. | Moisten thoroughly before lifting if it feels strongly attached; peel from the sides toward the center. | Typically removed after the film dries, often within about 10–20 minutes. | Can remove superficial oil and dead skin but may also cause dryness or irritation. It does not permanently shrink pores. |
| 8. Salicylic-Acid Pore Strips | Combines temporary adhesive removal with a beta-hydroxy acid intended to help loosen oil and dead skin. | Adhesive strip or film containing salicylic acid at a product-specific concentration. | Use on clean, dry skin exactly as directed; do not combine immediately with other strong exfoliants. | Moisten before slow removal if necessary, then rinse away residue and moisturize. | Usually a short treatment period, commonly around 10–15 minutes, depending on instructions. | May sting or cause dryness. Avoid on aspirin-sensitive skin, open wounds, severe irritation, or when using multiple exfoliating products without professional guidance. |
| 9. Waterproof or Sweat-Resistant Strips | Maintains adhesion during perspiration or brief exposure to water. | Water-resistant film, fabric, or polymer backing with a stronger pressure-sensitive adhesive. | Apply to completely dry skin and press the perimeter firmly; water resistance does not guarantee a seal during prolonged immersion. | Soak or dampen the strip first and remove slowly to reduce epidermal pulling. | Wear time depends on the instructions, sweat, skin oils, and water exposure. | Longer moisture contact may cause maceration or rash. Replace the strip if it becomes dirty, loose, or irritating. |
| 10. Latex-Free Sensitive-Skin Strips | Provides an option for people avoiding natural-rubber latex or seeking a gentler adhesive system. | Synthetic support material and latex-free adhesive; formulation differs by product. | Check the full materials statement, patch-test first, and apply to intact, oil-free skin. | Use warm water to soften the adhesive and peel slowly in the direction of hair growth. | Begin with a shorter wear period and increase only if the skin remains comfortable. | Latex-free products can still contain other allergens. Seek medical advice for widespread hives, facial swelling, breathing difficulty, or a severe reaction. |
