Ingredients Explained
Estriol, also called oestriol, is a steroid and a weak form of estrogen. This is not an INCI ingredient and we suggest speaking with a medical professional about using this ingredient.
You might know this ingredients as Matrixyl, a famous peptide.
Peptides are building blocks for protein. Palmitoyl Pentapeptide-4 consists of five amino acids. These amino acids include: 2 lysines, 2 threonines, and serine
This ingredients tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.
Thus, Matrixyl may help improve the look of wrinkles.

Learn more about Palmitoyl Pentapeptide-4Acetyl Hexapeptide-8, commonly known as Argireline, is a popular peptide in skincare. Itās often referred to as a āBotox-likeā ingredient because it helps reduce muscle movement.
By relaxing these micro-movements, Argireline may help minimize the appearance of fine lines and wrinkles. That said, itās not as powerful as Botox, and research on its long-term effectiveness is still limited.
Beyond smoothing, Argireline may also support collagen production. Collagen is the protein that helps keep your skin firm, bouncy, and well-hydrated by strengthening the skin barrier.
So while Argireline isnāt a miracle fix, it can be a helpful addition to a routine focused on both prevention and skin health.

Learn more about Acetyl Hexapeptide-8Hyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin.
This ingredient helps hydrate, soothe, and protect the skin.
What makes hyaluronic acid so hydrating? It has the capacity to bind or hold large amounts of water.
Fun fact: It is already naturally found in our bodies, such as the fluids of our eyes and our joints.
Studies find this ingredient to have anti-inflammatory and anti-microbial properties. This can help speed up wound-healing.
Hyaluronic acid can be irritating if the molecule has a low-molecular weight, or if the molecules are small.
One study found low-molecular weight hyaluronic acid to be pro-inflammatory, meaning some people may experience irritation. This is because our bodies use hyaluronic acid in the wound-healing process to signal to our bodies, via irritation, that something needs healing.
The same study found high-molecular weight hyaluronic acid to be anti-inflammatory.
These are some other common types of Hyaluronic Acid:
Learn more about Hyaluronic AcidCyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.
Learn more about CyclopentasiloxaneCaprylyl Methicone is a type of silicone.
It helps soften and soothe the skin by creating a thin film on top. This film helps trap moisture, keeping your skin hydrated.
PEG-16 Macadamia Glycerides isn't fungal acne safe.
Polysilicone-11 is a type of silicone.
PEG-12 Dimethicone/PPG-20 Crosspolymer is a type of silicone.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.Ā

- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas

Phosphatidylcholine is a type of phospholipid. Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids are skin-replenishing.
This ingredient can be found in the Lecithin of soybeans.
Jojoba Esters is a wax created from Jojoba oil. It is an emollient and film-forming ingredient. In bead form, it is an exfoliator.
This ingredient has high oxidative stability, meaning it doesn't break down when exposed to oxygen.
Its similarity to our skin's natural oils makes it a great emollient. Emollients help soften and soothe our skin by creating a barrier on top. This barrier helps trap moisture in, keeping skin hydrated.
It is created using either the hydrogenation or transesterification processes on jojoba oil.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

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