Brilliance Vitamin C Oil Serum – Brightening Treatment for Mature or Dull Skin

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.

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.

Layer after serum (such as Transform) or before your day and night creams. To focus on evening complexion and reducing age spots, use twice a day for six weeks. Apply directly to clean skin, warm in the palm of your hand, and press gently onto face.

When estrogen declines, skin changes. Collagen production slows, elasticity decreases, the barrier becomes more fragile and skin often appears drier, thinner and less resilient.

We call the most common concerns SWAG: Sagging, Wrinkles, Age Spots and Glow Loss. The FAB-4 was formulated specifically to address those changes—not adapted from a younger skincare line.

Our approach combines ancient botanicals with modern actives: unrefined Amazonian butters and oils paired with ingredients like Argireline®, Niacinamide and Hyaluronic Acid. Every formula was created specifically for menopausal and post-menopausal skin.
