Succinic Acid in Skincare
Succinic acid is a type of gentle facial acid that helps visually brighten the skin. It also has soothing and antioxidant benefits. Succinic acid has been compared in it's function to hyaluronic acid.
Glycolic Acid Vs. Vitamin C - Which Is Right For You?
Vitamin C and glycolic acid are both effective skin brighteners, but they work differently. Glycolic acid, an alpha hydroxy acid (AHA), exfoliates the skin, removing dead cells and revealing a brighter complexion. Vitamin C, with its strong antioxidant properties helps neutralize free radicals and stimulate collagen production, thus leading to a more even skin tone.
Ectoin Vs. Niacinamide - Which Is Right For You?
Both ectoin and niacinamide support the skin barrier - though they work differently to do so. Ectoin supports the skin barrier by binding moisture to the skin and creating a film on the skin that prevents water loss. Niacinamide helps to facilitate the production of ceramides and elastin, two critical parts of the skin barrier; it helps support the skin's natural shield.
Urea Vs. Glycolic Acid - Which Is Right For You?
Exfoliating is key to boosting your skin’s natural cell renewal, leaving you with a smoother, brighter complexion. By clearing away dead skin cells, it helps unclog pores, prevents dirt and oil buildup, and makes your other skincare products work even better. But with popular exfoliants like glycolic acid and urea on the market, how do you know which one is right for you?
Glycerin Vs. Hyaluronic Acid - Which Is Right For You?
While both glycerin and hyaluronic acid are excellent humectants with diverse applications, glycerin's smaller molecular size enables it to reach a bit further into the stratum corneum via aquaporins. This, combined with its molecular structure, allows glycerin to remain within the skin for a longer duration compared to water, which evaporates more readily.
Everything to Know About Solar Shade Sunscreen Broad Spectrum SPF 46 PA++++
Solar Shade Sunscreen includes bioactives such as microalgae, ethyl ferulate, and rice phytomolecules that each provide unique support to skin exposed to solar radiation. Ethyl Ferulate, a derivative of ferulic acid, neutralizes the signs of external aggressors while soothing the skin. Antioxidant molecules extracted from black, red, and brown rice increase the skin’s tolerance and defense against oxidative stress caused by solar radiation and pollution. Microalgae rich in β-carotene and astaxanthin help reduce formation of reactive oxygen species that are known to accelerate photoaging.
Organic UV Filters in Skincare
Organic UV Filters, often referred to as chemical filters, are sunscreen actives that contain carbon atoms, hence the "organic" origin. They are divided into UVA and UVB filters depending on the wavelength they absorb.
Microalgae in Skincare
Microalgae rich in β-carotene and astaxanthin to help reduce formation of reactive oxygen species that are known to accelerate photoaging.
Rice Phytomolecules in Skincare
Rice Phytomolecules are antioxidant molecules extracted from black, red, and brown rice that increase the skin's tolerance and defense against oxidative stresss caused by solar radiation and pollution.
Ethyl Ferulate in Skincare
Ethyl Ferulate is a lipophilic derivative of Ferulic Acid that soothes skin while helping to neutralize free radicals.
Polyglutamic Acid in Skincare
Polyglutamic Acid is a non-exfoliating natural moisturizing peptide proven to be a better hydrator than hyaluronic acid and collagen protein as it helps restore skin elasticity, smooth visual wrinkles, and increase production of NMF. This anionic soothing polymer can also help provide skin smoothness and protection against external aggressions.
Hyaluronic Acid Vs. Polyglutamic Acid - Which Is Right For You?
Both hyaluronic acid and polyglutamic acid offer immediate and noticeable skin hydration but polyglutamic acid can further improve dry skin by aiding in the skin’s natural production of NMF. Polyglutamic acid and hyaluronic acid can even be used together or layered for further hydration and skin plumping as neither of these materials has known compatibility issues.
Everything To Know About Multi-Quench Plumping Hydration Serum
Our Multi-Quench Plumping Hydration Serum is a humectant based serum with the star ingredient polyglutamic acid (PGA). Polyglutamic acid is a non-exfoliating peptide made up of several glutamic acid molecules. PGA is a moisturizing polymer that can be synthesized in the lab or created from the fermentation of natto and similar to hyaluronic acid, the molecular size dictates its function or skin benefit.
Osmolytes Blend in Skincare
Osmolytes Blend is a blend of organic compounds that regulate water balance to help provide an immediate moisturizing effect and help support the skin barrier function.
