Results

Finally I have found a solution to my bad skin. It's a convenient and quick way to improve my skin and it is very affordable too. ULTI-C3 is a real lifesaver for Australian dryness and i will always recommend it to my friends.

I am so glad I bought ULTI-C3, I use to have horrible cystic acne and this really helped reduce it significantly! Not only did it reduce the outbreaks and the severity of my acne, but it also really helped with the scarring and healing too!

Tonya, Melbourne, 23

I've been using ULTI-C3 for 3 months now and i think this oil is just phenomenal! Perfectly moisturizes my skin without making it too greasy and it goes on my skin so easy without any irritation. I'm happy with the improvement

THE SCIENCE OF ULTI-C3

STEP 1:

Collagen Stimulation

THD acts as a cofactor, promoting collagen synthesis by stimulating fibroblast activity, which contribute to skin firmness and elasticity. It also supports the synthesis of glycosaminoglycans

STEP 2:

Enhanced Lipid Permeation

Facilitates efficient permeation through the stratum corneum's lipid matrix. Once absorbed, it functions as a potent free radical scavenger, effectively neutralizing reactive oxygen species (ROS).

STEP 3:

Melanogenesis

THD Ascorbate modulates melanogenesis by inhibiting tyrosinase, a key enzyme in melanin production. This action reduces the synthesis of melanin, resulting in even distribution of pigment.

FAQ

IRIMI ULTI-C³ is designed to brighten dull skin, visibly reduce dark spots, smooth uneven tone, and help reverse signs of sun damage. It’s powered by THD Vitamin C — a highly stable, non-irritating form that penetrates deep for real results without the sting or stickiness.

Most customers notice visible improvements — like brighter, smoother, more even-toned skin — within just 14 days of consistent use. For best results, apply daily and allow the full skin renewal cycle (about 4–6 weeks) to maximize long-term benefits.

Each 30ml bottle lasts around 1-2 months with daily use (4-5 drops per application). A little goes a long way.

THD (Tetrahexyldecyl Ascorbate) is a next-generation, luxury-grade Vitamin C — rare, oil-soluble, and remarkably stable. Unlike traditional forms, it penetrates deeper, works longer, and delivers visible brightening and collagen-boosting results without irritation. It's the gold standard in high-performance skincare.
