Research by Dr. Sheldon Pinnell, the founding scientist of SkinCeuticals, has demonstrated that L-Ascorbic Acid can only penetrate the skin at a pH level below 3.5 (source: Topical L-Ascorbic Acid: Percutaneous Absorption Studies, 2001). Youtuber Liah Yoo evaluated the Klairs skincare line after 3-4 months of use because her followers kept requesting it. She begins her Klairs skincare review by prefacing that she doesn’t actually think the products are suitable for sensitive skin because they use essential oils that may trigger allergic reactions. 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). 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 lavenderresults in increased risk of sensitivity. Hypoallergenic, effective, affordable. There’s really nothing else you can want from a vitamin C serum.

About Sokoglam

Other (less serious) concernsare if EGF can properly penetrate the skin (as it is a medium-sized, polar molecule, so a special deliverysystem is probably needed), if it can affectcollagen synthesis (or just works on the surface plumping up only the upmost layers of the skin) and if it has beneficial effects at all when used in isolation versus when used in a "conditioned media" that contains lots of growth factors resembling the synergistic balance found in the skin. In the mornings I add about 1-2 drops into my moisturizer. It really depends on my mood and what my skin is up to that day. Pure Vitamin C:also called L-Ascorbic Acid (LAA), this is the form of Vitamin C that your body can use directly which allows it to provide the most skin benefits And call me old-fashioned, but I like it when my products last longer than a month. That’s a lot of serious wastage if you have to buy yourself a new bottle of serum every month when you’re not even halfway done with it. At first I wasn't convinced and let it sit on my shelf. Then I used it day and night just to use it up, whilst my prescription strength cream had irritated my skin and I'm a convert. I've not seen any other product minimise my pores and even out my complexion like this has. It even cleared a rash on my chest almost overnight, that nothing else could.

A little goes a long way. After 3 months of daily use, my little bottle is still half full which is awesome.

Klairs lean heavily on natural ingredients to give you skincare products with a low chance of skin irritation while focussing on hydration. Hydrated skin is happy skin, and when you start using Klairs, you’ll start feeling the difference. Which Klairs products are the most popular? One of the biological activities of thecentellosides isto be able to stimulate GAGs(glycosaminoglycans - polysaccharides that are part of the liquidy stuff between our skin cells), and especially hyaluronic acid synthesis in our skin. This is probably one of the reasons why Centella Asiatica Extract has nice skin moisturizingproperties that was confirmed by a 25 people, four weeks study along with Centella's anti-inflammatory effects. In short, more free acid forms of L-Ascorbic Acid are available at lower pH levels and this is a good thing because only the free acid form can penetrate your skin's oily barrier. Wishcompany itself is a South Korean start-up founded in 2010 by CEO Ryan Soungho Park, who, at the time, had noticed an increasing global demand for Korean cosmetics. He was impressed by Klairs not only because of the simple attractiveness of their products, but also because they were effective on his own sensitive skin.

When I use it, I can feel my skin feel a little bit of the warmth of the Vitamin C serum soaking into my skin. It causes no irritation, which is great because if my skin is happy, I’m happy.

EGF is a special snowflake when it comes to skincare as it was the first Growth Factor that made its way into cosmetic products and it isalso the most common one. The Americanbiochemist,Stanley Cohen discovered EGF and was awarded a Noble prize in 1986 for it. As the Noble prize may signify, the molecule is significant and powerful and directly stimulatesthe proliferation of epidermal cells. Prevents Damage:as an antioxidant powerhouse, Vitamin C mops up free radicals to prevent oxidative damage from UV radiation, pollution, stress, and aging Since its foundation, Klairs has continued to develop products using the most effective ingredients and raw materials to best treat sensitive skin, improving elasticity and soothing irritation. All Klairs products are cruelty-free, and the majority of them are now vegan. When it comes to Sh-Oligopeptide-1 in a cosmetic product, it haspretty well-established woundhealing and skin renewal properties. It might even do more than that. According to a 2012 study on a serumcontaining barley bioengineered epidermal growth factor, "clinical evaluations showed statistically significant improvement in the appearance of fine lines and rhytids, skin texture, pore size, and various dyschromatic conditions apparent within the first month of use, and continuing improvement trends for the duration of the study" (which was 3 months). At a pH of 3.81 (and with only 5% L-Ascorbic Acid), it's unlikely that you're going to get much Vitamin C into your skin, which means you won't get those amazing skin benefits that we discussed earlier (brightening, tightening, and antioxidant protection).

Klairs Freshly Juiced Vitamin Drop is a hypoallergenic vitamin C serum formulated with 5% vitamin C to treat dead skin cells, brighten and even out skin tone, and help tighten the appearance of pores. I’ve spoken with research and development skin care specialists in Korea, and they echo my sentiments. There are also tons of studies that show Vitamin C in a stabilized form is just as beneficial.

Another pro is that lavender oil has some nice antimicrobial and antibacterial properties. It also has some localpain relieving and muscle relaxing magical powers. Lavender oil is also often claimed to have anti-inflammatory properties. 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. (The main components of the flower essential oil are linalyl acetate and linalool [around 80% the two together] while it is 1,8-Cineole [around 65%] in the essential oil of the leaves.) This has become a staple in my routine. I've been burned (literally) before by other vitamin c products, but this has never given me issues and does a really good job at brightening and fading dark spots." - Gabrielle F. It works. Bottomline, this serum just works. It’s not an overnight miracle worker (nothing is) but with consistent use, my skin looks brighter, my acne scars look lighter and my complexion looks healthier.
