Seborrheic Dermatitis - "Since using the mask, the skin around my nose has become really dry and angry looking, it's flaky and red with little spots, different to the usual spots that I get"
If you think you may have any form of dermatitis visit your GP, ask at your surgery if there is a Dr or nurse that specialises in skincare, they can diagnose and treat if necessary.
Overproduction of oil - "my skin is just so oily, I cleanse and then within 10 minutes I can see the oil at the opening of my pores, within a few hours I'm like an oil slick, I can't wear make-up at the moment, it's just sliding off!"
The skin is producing extra oil to overcompensate for the loss, keep on moisturising twice a day, it may seem crazy to moisturise when your skin is already oily but it will help to balance your skin. Avoid using strong active ingredients or soap.
Broken capillaries - "Oh my god please say there's something you can suggest to help? I have all these little red lines on my cheeks, they're not too noticeable and I can cover them with make-up but how can I get rid of them?"
Hopefully they'll fade in time, again be sure to not use any harsh products on the area. If they don't fade then unfortunately topical products won't help, they'd need professional treatment such as laser.
Melasma - "I used the mask on the Monday evening and Tuesday I went on the sunbed, now I have 2 dark patches on my cheeks and they don't seem to be fading at all, it didn't say anything on the package about not going in the sun!"
This is probably the worst side effect because melasma doesn't usually disappear on it's on, it can fade in time, usually taking a few years but typically melasma would need laser treatment or prescribed skincare.
These are some of the more severe emails, the others are generally people experiencing a little dryness and soreness.
Conclusion
If you or someone you know is using these masks, I highly recommend you stop before you do start to see negative results. Blackheads are awful, I have oily skin and had acne as a teenager, I know how earth shattering skin conditions can be. But no matter what your age, your skin needs to be cherished and loved, treat your skin with the same care you'd treat a youngsters skin, you wouldn't scrub their skin or apply anything that was painful to remove (having seen the videos on youtube, removal of these masks looks pretty excruciating!). A good daily regime of cleansing, toning and moisturising using acids to gently exfoliate is essential, salicylic acid if you have blackheads and blocked pores, good skin requires daily TLC, there are no quick fixes when it comes to skin health.
