Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages!
Most researchers focus on lactoferrin’s benefits for Skin, being the body’s largest organ, with promising results! Studies showed that lactoferrin was able to enhance skin moisture and texture among subjects experiencing dehydrated and dry skin during the winter months. In addition, lactoferrin was proven to be effective in addressing inflammatory lesions and improving overall skin health among people with mild to moderate acne.
Objective: Lactoferrin, an innate defense iron-binding protein, possesses antimicrobial and anti-inflammatory activities. Beneficial systemic effects on inflammatory diseases have been proposed. The aim of the present study was to explore the efficacy and tolerability of oral bovine lactoferrin supplementation in subjects with mild to moderate facial acne vulgaris.
Methods: In this open-label, single-arm study, 43 adolescents and young adults were enrolled to take a chewable tablet formulation of bovine lactoferrin twice daily for 8 weeks. The primary efficacy endpoint was the improvement in acne lesion counts compared with baseline. Tolerability was evaluated on the basis of adverse event frequencies.
Results: Thirty-nine subjects, aged 17.5 ± 3.8 years, completed the study per protocol. At the end of the study (week 8), a mean reduction in inflammatory lesion count of 20.2% (-2.2 ± 7.0, p = 0.054), in non-inflammatory lesion count of 23.5% (-6.2 ± 9.8, p < 0.001), and in total lesion count of 22.5% (-8.4 ± 13.1, p < 0.001) was observed as compared with baseline. At study conclusion, 76.9% (30 of 39) of subjects showed a reduction in total lesion count. The results for inflammatory acne lesions were variable over the study course. None of the subjects experienced a lactoferrin-related adverse event during the trial.
Conclusion: Despite the limitations of an uncontrolled, open-label study, the results from this study indicate that lactoferrin in mild to moderate acne vulgaris is well tolerated and may lead to an overall improvement in acne lesion counts in the majority of affected adolescents and young adults when administered as a dietary supplement on a twice daily regimen. Further randomized, placebo-controlled trials of longer duration appear warranted.
