Rilastil D-Clar Depigmenting Concentrate Drops

Methylpropanediol is able to add a bit of moisture to the skin. It also helps other ingredients be better absorbed into the skin, such as salicylic acid.

This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.

Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

Two powerful components found in the wild soybean include genistein and diadzein. These two isoflavones are potent antioxidants with anti-inflammatory properties. Genistein in particular has been found to prevent redness caused by UV exposure.

One study from South Korea found wild soybean extract to help promote hair growth at the cellular level.

The wild soybean plant is a cousin to the famous soybean that gives us tofu, soy milk, and soy sauce.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

3-O-Ethyl Ascorbic Acid interferes with the process of skin darkening, helping to reduce hyperpigmentation. It also encourages the skin to produce more collagen.

Once applied, 3-O-Ethyl Ascorbic Acid is converted to Vitamin C deeper in the skin's layers. This process is slow but makes this ingredient more tolerable for skin.

The optimum pH range for this ingredient is 4 - 5.5

Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Caprylic Triglyceride has not been found to be toxic for human use in concentrations under 50%.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.

Vaccinium Myrtillus Fruit Extract also helps reduce irritation.

This ingredient has antimicrobial properties and helps prevent the growth of bacteria in a product.

Leuconostoc is used to make the traditional Korean side-dish, kimchi. It is also used to make sourdough bread (both incredibly yummy foods).

Rucinol works by preventing tyrosinase from creating more melanin. According to a study from 2013, rucinol is more effective than other tyrosinase inhibitors such as hydroquinone, arbutin, and kojic acid.

According to a manufacturer, this ingredient is sensitive to air. Good formulations should account for this to keep your rucinol effective.

As an emollient, lecithen helps soften the skin and creates a barrier to keep moisture in.

As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can help ingredients be better absorbed by the skin. The phospholipids in Lecithin can produce liposomes. Liposomes help other ingredients get through the skin barrier.

Due to its fatty acid content, this ingredient may not be fungal-acne safe.

Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

Glycolic acid is a derivative of sugarcane. While glycolic acid is an AHA with exfoliating properties, sugarcane is not an AHA.

A study from 2021 found the compounds in sugarcane extract to have antioxidant, antimicrobial, and anti-inflammatory activity. The study also suggests these compounds can inhibit skin ageing enzymes and promote collagen synthesis.

Emollients help soothe and soften the skin. They do this by creating a protective film on your skin. This barrier helps trap moisture and keeps your skin hydrated. Emollients may be effective at treating dry or itchy skin.

This ingredient may or may not be vegan, depending on the source.

Peg-40 Hydrogenated Castor Oil may not be fungal-acne safe. We recommend speaking with a professional if you have any questions or concerns.

Arginine isn't fungal acne safe when used in the presence of other lipids (fats, fatty acids, oils, esters, etc). Oils and fats occur naturally within the skin, so take caution when using Arginine if you're prone to fungal acne.

The DNA is extracted from several different animal sources, including: calf thymus, the gonadic tissue of a male sturgeon, or herring / salmon sperm.

You have probably seen this ingredient in anti-aging skincare. But what is it?

DNA is composed of nucleotides, or chemical building blocks. Nucleotides include adenine (A), thymine (T), guanine (G), and cytosine (C). Talk about a flashback to biology! Nucleosides are formed from these nucleotides.

The science behind Sodium DNA is based on an ingredient called Polydeoxyribonucleotide or PDRN.

PDRN are DNA fragments mainly extracted from the sperm cells of trout or salmon. Meaning, PDRN can be derived from Sodium DNA.

PDRN consists of chains of nucleotides and nucleosides mentioned above. They can range anywhere from 80 - 2000 pairs.

Studies show PDRN has the following properties:

Further studies are needed to truly confirm this ingredients anti-aging ability (Remember, retinol has decades of research!).

When using this ingredient, is is best to ask a brand about the source of their Sodium DNA. You'll want to find products where the Sodium DNA is sourced from fish. Some Sodium DNA is derived from calf / cow thymus.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

It can also be mildly exfoliating due to the citric acid, an AHA.

Citrus fruits are rich in flavonoids, alkaloids, and vitamin C.

And of course, lemons are rich in Vitamin C. Vitamin C helps with skin-brightening and increasing collagen production.

The acidity of lemons may work as an astringent for acne.

However, lemons can also cause skin sensitivity due to its limonene content. It can also increase photosensitivity, or sensitivity to the sun.

This ingredient is also used to add a lemon scent to products.

Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.
