What it does

Our Brilliance serum has been a labor of love to find the ingredients that work the hardest to reduce age spots, discoloration, and hyperpigmentation so that skin will actually glow.

Brilliance is a combo of a massive amount of Vitamin C and an active called Teprenone that is said to work on the origin of youth and improve tissue quality while extending cell lifespan by one-third. With 10% Vitamin C, this is one dedicated serum to have in your arsenal. Teprenone is said to work on the origin of youth and improve tissue quality while extending cell lifespan by one-third.

Undecylenoyl phenylalanine is a skin-lightening agent made of natural amino acids with a lipid residue. Together, this blend helps smooth rough skin, fine lines, and enlarged pores. It lies beautifully under Radiance Retinal Gel for those who want to create that Vitamin C + A marriage.

Featuring:  Tetrahexldecyl Ascorbate (Vitamin C) + Teprenone, Borage

What It Does

What makes Brilliance essential in an anti-aging routine?
It combines antioxidant protection and brightening power through a lipid-soluble Vitamin C (Tetrahexyldecyl Ascorbate), helping to reduce discoloration, age spots, and fine lines while supporting collagen renewal in mature or post-menopausal skin.

How does it help with uneven tone and hyperpigmentation?
Pracaxi and Vitamin C work together to lighten the look of age spots and sun-induced discoloration for a more even, radiant complexion.

Can it help with texture and enlarged pores?
Yes – its blend of antioxidant-rich botanicals and lipid actives helps refine texture and smooth roughness, leaving skin visibly brighter and more even.

Why is Teprenone included?
Teprenone (a youth-extending active known as Renovage®) is said to improve tissue quality and prolong cell longevity by up to one-third — helping mature skin retain firmness and elasticity.

How does it fit with other JustUs products?
Brilliance is formulated to layer seamlessly beneath Radiance Retinal Gel or above Transform serum for maximum brightening and anti-aging benefit in mature-skin routines.

Ingredients

What does Vitamin C (Tetrahexyldecyl Ascorbate) do for aging skin?
This lipid-soluble form of Vitamin C penetrates deeply to brighten dull complexions, fade dark spots, and stimulate collagen production without the irritation often caused by acidic Vitamin C.

Why include Teprenone (Renovage® Active)?
Known as the “longevity molecule,” Teprenone helps improve skin structure and extend cell lifespan — visibly reducing signs of aging such as fine lines and uneven tone.

What role does Borage Oil play in the formula?
Borage is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid that soothes dry, fragile skin and supports a healthy barrier — ideal for mature and post-menopausal skin.

What do the desert extracts add to the formula?
The desert botanicals thrive in extreme conditions, making them rich in antioxidants and phytonutrients that protect against environmental stress, boost brightness, and help skin retain resilience even in harsh climates.
