If you've got large angry red spots - you've got acne. About 85 per cent of teenagers develop acne. The sudden outflow of oil produced in puberty damages the cells lining the hair follicles and sebum ducts. Also dead cells mix with it and block the pores. That trapped material is a rich feeding for bacteria which aggravates inflammation causing swelling, redness and sometimes pus. Same happens if you are going through hormonal imbalances or stress that increase the production of sebum. With BIOSKIFORTE you can heavily reduce the effects of acne.
