Previously I mentioned about the potential positive effects of whey protein on acne; and as this is a site with a large number of members who use this popular supplement, I thought I would elaborate on the point a little further.
Whey itself is a collection of globular proteins which are seperated from milk plasma. One of these proteins goes by the name of lactoferrin. If anyone has used any over the counter acne medications before you may have come across this in the ingredients list. It seems commonly known as an anti-inflammatory, yet I have not revealed much scientific data based on this claim.
Lactoferrin itself is quite a magical protein boasting a number of important properties. It is an iron-binding protein which has anti-fungal, anti-bacterial and anti-viral functions as well as plenty more!
There have been some rough studies conducted on the proteins' effect on acne vulgaris; and I feel their conclusions do warrant study.
Here is the first I stumbled across:
Efficacy and tolerability of oral lactoferrin supp... [Curr Med Res Opin. 2011] - PubMed result
As is similar with numerous studies there are no guidelines as to the severity of acne. What constitutes mild,moderate or severe acne? I would love for a study to be more specific on this. This study does not cover severe acne; but I believe it would be safe to say the conclusions will still apply.Quote
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.
Here is another frustration of the test! It is conducted as a uncontrolled open-label study; as well as boasting a small sample size and a short time frame.Quote
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.
The results are interesting though:

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)Quote
in non-inflammatory lesion count of 23.5% (-6.2 ± 9.8, p < 0.001)Quote
and in total lesion count of 22.5% (-8.4 ± 13.1, p < 0.001) was observed as compared with baseline.So this rough study is providing some credibility for lactoferrin's use against acne vulgaris. There are no dosages specified in the study; so that warranted further research.Quote
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.
Here is another study:
Dietary effect of lactoferrin-enriched fermented m... [Nutrition. 2010] - PubMed result
They too are mentioning the lack of scientific basis for the argument.Quote
Lactoferrin, a whey milk protein after removing precipitated casein, has a prominent activity against inflammation in vitro and systemic effects on various inflammatory diseases have been suggested.
Once again a small sample size!Quote
Patients 18 to 30 y of age were randomly assigned to ingest fermented milk with 200 mg of lactoferrin daily (n = 18, lactoferrin group) or fermented milk only (n = 18, placebo group) in a 12-wk, double-blind, placebo-controlled study.
The dosage they are using (200mg) is double the advised daily dosage of 100mg.
The results once again are impressive:
One good positive about this study is their systematic approach to grading the acne using skin ph, skin hydration as well as legion count.Quote
Acne showed improvement in the lactoferrin group by significant decreases in inflammatory lesion count by 38.6%, total lesion count by 23.1%, and acne grade by 20.3% compared with the placebo group at 12 wk. Furthermore, sebum content in the lactoferrin group was decreased by 31.1% compared with the placebo group. The amount of total skin surface lipids decreased in both groups. However, of the major lipids, amounts of triacylglycerols and free fatty acids decreased in the lactoferrin group, whereas the amount of free fatty acids decreased only in the placebo group. The decreased amount of triacylglycerols in the lactoferrin group was significantly correlated with decreases in serum content, acne lesion counts, and acne grade. No alterations in skin hydration or pH were noted in either group.
Take the fermented milk out of the equation and look at the lactoferrin individually.
It does certainly appear that lactoferrin has acne healing properties and as a component of whey protein. one can extrapolate it would yield the same effect. The big problem here is the other ingredients which make up whey protein. A single ingredient could easily be offset by numerous others.
I still believe whey protein is not a supplement to be overly concerned over when it comes to acne. I feel for the majority of individuals; you will see little correlation between consumption and an increase in acne. An increase in acne will more likely come from training or other constituents of your diet. As I mentioned though; this is my generalised opinion and some individuals may see a drastic correlation.
Lactoferrin is available as an individual supplement and I may experiment with it myself in the near future.
