This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

As a cosmetic ingredient, Arginine has antioxidant properties and can also help repair damaged skin. This ingredient is derived either synthetically or from animals.
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.
Learn more about ArginineThreonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Our skin uses threonine for creating collagen and elastin. Humans are not able to create threonine and must get it through eating foods such as fish, lentils, poultry, sesame seeds, and more.
Serine is an amino acid naturally found in our body. Our bodies use amino acids to create protein.
Amino-acids help give keep our skin hydrated. They play an important role in the skin barrier, which keeps the skin plump and firm.
Serine is a non-essential amino acid, meaning we don't need to obtain it from eating foods.

Our skin uses proline as one of the building blocks for producing collagen.
In medicine, proline is used as an osmoprotectant. This means it helps prevent oxidative degradation in other drugs.
Our bodies are able to produce proline naturally, but certain conditions may inhibit this production. In that case, proline can be obtained from eating egg whites, soy protein, dairy products, asparagus, mushrooms, and seaweed.

Studies show this ingredient tells our body to create more collagen and elastin. Collagen is a protein that makes connective tissue. Elastin is the protein responsible for giving our skin elasticity. Our bodies start to slow down collagen and elastin production with age.
Boosting collagen and elastin production can help create a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin. It's a win-win situation!
This ingredient helps with scar healing. This is because it breaks down damaged collagen, the main component of scar tissue. It may also help with reducing sunspots, acne scars, and uneven skin tone.

I was breaking out for 3 months and had no idea what was going on. Then my mom mentioned she’s getting small bumps around her jawline from another peptide serum (Skin1004) and it clicked. Stopped using it week ago and didn’t get a single pimple.
Didn’t see any positive results.
No difference seen so far as i started last week, goes on nice and absorbs fast, no scent whatsoever and pretty hydrating
EDIT: GAVE ME CLOSED COMONDONES LIKE THE OTHER REVIEWER. DONT USE.
