The reasonable frequency of use of blackhead nose strips is as follows
1. Recommended frequency of regular use
Normal skin (neutral/combination skin)
1-2 times a week: can effectively clean blackheads and avoid pore clogging.
Single use ≤15 minutes: exceeding may damage the skin barrier.
Oily skin
≤3 times a week: those with vigorous sebum secretion can increase moderately, but the skin condition needs to be strictly monitored.
Matched with oil control ingredients: nose strips containing activated carbon and salicylic acid are more suitable.
Sensitive/dry skin
Once every 2 weeks or less: avoid aggravating stratum corneum damage, and moisturize more after use.
Avoid alcohol ingredients: mild materials such as Tencel membrane cloth are preferred.

Key points
Frequent use prohibited
Daily use will damage the stratum corneum, leading to enlarged pores, redness, swelling and allergies.
Violent removal of the peel-off nose patch may offset the effect of previous care.
Necessary care steps
Apply astringent water after use: prevent pore expansion and repair skin barrier.
Avoid superimposing irritating products: Do not use exfoliating ingredients such as salicylic acid and fruit acid on the same day.

Alternative solutions for reference (when blackheads are severe)
Salicylic acid care: 7-15 days/time to dissolve pore keratin.
Micro-bubble cleansing: 1-2 times/month for deep cleansing.
Photorejuvenation: according to the course of treatment to control oil and shrink pores.

Summary and recommendations
Best practice: Use once a week for normal skin, ≤3 times/week for oily skin, ≤1 time/2 weeks for sensitive skin.
Signal to stop use: If redness, peeling or stinging occurs, stop use immediately and repair the skin.
Long-term strategy: Gentle cleansing + regular medical beauty treatments as the main method, supplemented by nose patches.

Limitations and alternatives
Easy to damage pores: Violent removal of peel-off nose strips may cause pores to loosen. Choose a three-step nose strip (extraction + adsorption + astringency) to reduce damage.
Cannot eradicate blackheads: Only removes surface blackheads. Use regularly. Salicylic acid (fat-soluble) can dissolve deep oils, 1-2 times a week.
Use with caution for sensitive skin Strong peel-off nose strips may cause redness and allergies. Mild nose strips (such as Tencel mask cloth) or low-concentration fruit acid.

Preparation before use
Skin check
Confirm that there are no wounds, redness, swelling or inflammation on the nose (broken skin is prohibited).
Deep cleansing
Warm water + amino acid facial cleanser to wash away grease and avoid dust from hindering adsorption.
Pore relaxation
Apply hot towel/steam to the nose for 1-2 minutes (≤40℃) to soften the stratum corneum.
Note: Sensitive skin can skip the hot compress and directly moisten the nose
Key steps for nose patch operation
Keep the nose slightly moist
The nose patch needs to be applied to moist skin to enhance adhesion (dryness will cause it to fall off).
Accurately fit the nose shape
Press along the bridge of the nose to expel bubbles and ensure full coverage of the nose wings and nose tip.
Control the use time
Wait for 15-20 minutes (do not exceed the time limit) for the gel to completely dry before tearing it off.
Key to the tearing direction
Tear it off at a uniform speed from bottom to top to reduce pore damage.
Wrong demonstration: horizontal tearing can easily cause skin sagging
Post-use care (preventing enlarged pores)
Instant cleansing
Wash away residual colloid with warm water, and avoid secondary stimulation with abrasive products.
Ice compress to tighten pores
Apply refrigerated toner for 5 minutes or press with an ice towel to inhibit pore expansion.
Barrier repair
Apply a moisturizer containing ceramide and panthenol to soothe damaged stratum corneum
