Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

Masking, Skin Conditioning

Arginine is an amino acid that is important for human development. Your body uses is it to produce hair keratin and skin collagen.

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.

Buffering, Masking

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

This only works if you’re consistent. I only saw a difference when I applied this day and night. They released a different formula for males. So, maybe that formula would work better on me.

I've slept on peptides for way too long. Don't make the same mistake!

This product has made my skin look more youthful in a way I didn't know was possible, and has increased my skin's baseline level of hydration in a way that other hydrating products have not.

I love this serum! Copper peptides speed up the healing process of rosacea / eszema / damaged skin barrier etc.
It has also anti aging properties, its hydrates…it pretty much got rid of my “dehydration” within 2 days and calmed down my rosacea within 1 day.
it’s just an all rounder that I certainly implement in my skin routine all the time.
However, it’s important to note: copper peptides break Show more
