“Static is caused by increased electrons in our hair strands,” explains Miko Branch, a hair care expert. You may have intentionally caused hair static as a child by rubbing a balloon against your head, causing crazy flyaways-but unruly strands are not fun as an adult. However, dry climates can cause a whole new pesky styling concern: Static. A sunscreen with BP-3 is definitely better than no sunscreen.If you’re prone to frizz, you know what a relief it can be to get a break from poofy hair-inducing humidity. However, if you find a formula that you love and contains BP-3, we do not think that you should throw it away. Overall, BP-3 is probably our least favorite sunscreen agent and we prefer sunscreens without it. It can be used in concentrations of up to 10% in the EU and up to 6% in the US. On the up side, sunscreens are pretty well regulated in several parts of the world, and BP-3 is considered " safe as used" and is an allowed sunscreen agent everywhere. If that was not enough, Wikipedia claims that BP-3 is nowadays the most common allergen found in sunscreens, and the always-trustworthy smartskincare writes that " have been shown in some studies to promote the generation of potentially harmful free radicals". In fact, a 2004 follow-up study to examine the estrogenic effect of sunscreens when used topically on the whole body found that "the endogenous levels of reproductive hormones were unaffected" (even though BP-3 could be detected both in plasma and urine, so its absorption is no doubt too good). Estrogenic activity was confirmed only in-vitro (in test tubes) and when taken orally by lab animals, and not when used topically as you would normally. Overall, we think that the orange fruit extract is a very complex ingredient with lots of potentially good things in it, but we could not find proper in-vivo (made on real people) studies made with standardized extracts to validate what it really does or does not under real-world use cases.Īnother concern of BP-3 is that it shows some estrogenic activity, though it's probably not relevant when applied topically to the skin. If the amount is big enough to worry about is questionable, probably not, however, the same question applies to all the nice beneficial compounds. Some essential oil content is usually also present in citrus fruit extracts, which means a nice scent and antibacterial properties, but also some questionable compounds such as fragrance allergen limonene or phototoxic compound bergaptene. The orange extract also contains carbohydrates, aka sugars (mostly glucose, fructose, and sucrose, but also some bigger polysaccharides such as pectin) giving the ingredient some moisturizing properties. Some of them (namely hesperidin and luteolin) might even have skin brightening activity by inhibiting tyrosinase, the famous enzyme needed for melanin production. If you want vitamin C in your skincare, that is smart, but do not rely on orange fruit extract for it.įlavonoids ( hesperidin, naringin, luteolin, and ferulic acid) are also nice active compounds with possible antioxidant, anti-inflammatory, and vasoprotective effects. A well-known one is the antioxidant vitamin C, aka ascorbic acid, but the dosage will vary based on the extraction method, and it’s possible that some of the ascorbic acid content will degrade before extraction process even takes place. If that's the case, it is usually combined with other AHA containing fruits such as bilberry, sugar cane, lemon, and sugar maple in a super popular ingredient mix trade named ACB Fruit Mix.īut orange fruit is loaded with lots of other active compounds with a wide variety of possible effects. It contains mainly citric acid and some malic acid, AHA exfoliants known for their skin renewing properties. Lavandula Angustifolia (Lavender) Flower ExtractĪ very common scenario is that Citrus Aurantium Dulcis Fruit Extract is on the ingredient list for its mild, natural exfoliant properties.
