![]() ![]() We are highly skeptical what effect a tiny amount of AP has in a formula. Even if it can be converted, the palmitate part of the molecule is more than the half of it, so the efficacy will not be good and we have never seen a serum that contains a decent (and proudly disclosed) amount of AP. This does not mean that ascorbyl palmitate cannot penetrate the skin (because it can, it's oil soluble and the skin likes to absorb oil soluble things) but this means that it's questionable if ascorbyl palmitate can be converted into pure Vit C in the skin. Second, a study that examined the skin absorption of vitamin C found that ascorbyl palmitate did not increase the skin levels of AA. A great study in the Journal of Cosmetic Dermatology compared a bunch of vitamin C derivatives and this derivative was the only one where the study said in terms of stability that it's "similar to AA". Overall, it makes us sad to write bad things about such a lovely plant, but when it comes to skincare, you will be better off without lavender.įirstly, it's stability is only similar to that of pure ascorbic acid (AA), which means it is not really stable. This was the year when using dried lavender flowers in pillows, wardrobes, and elsewhere became fashionable in Japan, so it seems that increased exposure to lavender results in increased risk of sensitivity. There is also an often cited Japanese study that made patch tests with lavender oil for 9 years and found a huge increase in lavender oil sensitivity in 1997 (from 1.1% in 1990 to 8.7% in 1997 and 13.9% in 1998). To make things even worse, lavender oil seems to be cytotoxic from concentrations as low as 0.25% (concentration up to 0.125% were ok). The two main components are linalyl acetate (about 50%) and linalool (about 35%) and both autoxidise on exposure to the air forming strong contact allergens. Now, let us look at the cons: similar to a bunch of other essential oils, the main components of lavender oil are potentially irritating fragrant components. (The main components of the flower essential oil are linalyl acetate and linalool while it is 1,8-Cineole in the essential oil of the leaves.) We have found a study confirming this but it was the essential oil of the leaves and not the much more commonly used flowers and the two differ in their main chemical compounds very much. Lavender oil is also often claimed to have anti-inflammatory properties. It also has some local pain relieving and muscle relaxing magical powers. ![]() Rosmarinus Officinalis (Rosemary) Leaf OilĪnother pro is that lavender oil has some nice antimicrobial and antibacterial properties.
