During the hot summer days, many people use "sanfu stickers" to relieve discomfort. However, some people may develop blisters. Why does this happen and how should these blisters be treated?
Why do blisters form from sanfu stickers?
Sensitive skin
The blistering phenomenon after using sanfu stickers usually occurs in children with sensitive skin. This is because the medication in sanfu stickers contains certain spicy and irritating substances, which can easily cause blisters in children with delicate skin.
Prolonged application time
Although children have sensitive skin, their application time is relatively short. However, for adults, it is not recommended to exceed 4 hours of application time. The medication in sanfu stickers can cause a certain degree of spicy and irritating effects on the skin. If the application time is too long, blisters may inevitably occur.
Improper medication dosage
If a patient develops blisters after using sanfu stickers, it may be related to improper medication dosage. Therefore, it is necessary to seek treatment in a reputable hospital to avoid blisters caused by improper operations.
How to treat blisters from sanfu stickers
Treatment for small blisters
If the blisters are small, no special treatment is required. Let them naturally absorb. If the child experiences pain, apply a moist burn ointment to alleviate the pain.
At the same time, avoid scratching the blisters to prevent infection.
Treatment for large blisters
If the blisters are larger, under the guidance of a doctor, they can be punctured using a silver needle or sterile syringe. Drain the fluid from the blisters and disinfect them with iodine to prevent infection.
Notes:
1. There is a risk of infection after the blisters rupture. Pay attention to protecting the wound and it is best to seek medical treatment.
2. Do not take a shower immediately after puncturing the blisters. Wait for 12 hours before showering. When showering, do not rub the local skin. Generally, it takes 1-2 days for the blisters to gradually heal.
Treatment for extensive blisters
If large-scale blisters or severe allergic reactions occur after using sanfu stickers, stop applying them immediately and seek medical treatment for appropriate management.
Will blisters from sanfu stickers leave scars?
If no blisters or very small blisters appear after using sanfu stickers, scars are generally not left. However, if large blisters or extensive blisters appear, it is likely that scars will be left.
How to prevent scars from blisters caused by sanfu stickers
Use vitamin E for scar removal
After the blisters scab, apply vitamin E. Vitamin E can maintain skin elasticity, fade pigmentation, and has a good effect on eliminating skin scars.
Usage: Pierce the vitamin E capsule with a needle and apply the liquid inside to the scar. Gently massage for 5-10 minutes, twice a day, persisting for good results.
Apply ginger slices
After the blisters scab and fall off, gently wipe with ginger slices. Ginger can inhibit the continued growth of granulation tissue and prevent scarring after blistering.
Massage for prevention
Massage the scar with the base of your palm three times a day, 5-10 minutes each time. This method is most effective for fresh scars, and less effective for old scars.
Apply lavender essential oil
Lavender essential oil, extracted from lavender, can clear heat and detoxify, remove acne marks, cleanse the skin, control oil, and has anti-wrinkle and skin rejuvenation effects. It has a certain effect on removing scars after blistering.
How long does it take for scars from sanfu stickers to disappear?
The time it takes for scars from sanfu stickers to disappear depends on individual physical conditions and post-care. Generally speaking, children have faster skin metabolism and are less prone to scarring. With scar removal care, scars can usually completely disappear within six months.
If the person is older, even with scar removal care, it may take several years for the scars to disappear, or they may not disappear at all.
Are blisters from sanfu stickers a detoxification process?
The blistering caused by sanfu stickers is a stress response of the skin and is not a detoxification process.
The main reason for blistering from sanfu stickers is the high heat generated by the medication in the sanfu stickers, which burns the skin. It is mainly related to the differences in individual physical conditions and the duration of application, and does not belong to the detoxification response of the human body's skin.
