skin-transition.png__PID:0766564c-d044-48b3-ae17-e71a972c293f

Over time, skin’s natural collagen levels decline, leading to changes in texture, tone, and radiance. Protecting and maintaining skin vitality requires a thoughtful approach—one that delivers powerful, effective ingredients without irritation.

At Rejuvaus, we’ve perfected the balance of encapsulated Vitamins A, B3, and non-acidic Vitamin C, allowing these actives to be absorbed deeply while remaining gentle enough for twice-daily use. The result is skin that feels refined, resilient, and visibly radiant, with enhanced protection against daily environmental stressors and the signs of aging.

FAQS

Why is one pump enough?

One pump (0.2 ml) is enough, as the formula is so concentrated. Using more is wasteful since the skin can't utilise the excess. With pure active ingredients and no fillers, the serum spreads easily, absorbs quickly, and penetrates deeply.

There are many ingredients in each bottle. Are they safe?

Yes, many of the ingredients are in a form which are generally deeply absorbed and slowly released from an encapsulated form. This allows for a gentle non-irritating delivery across the skin over 12 hours. Due to the absence of some of the more harsh and toxic filling substances, petrochemical and silicone type ingredients, synthetic fragrances, pigments, and toxic preservatives, the products are extremely well tolerated. We do recommend not using with any other skincare range to see maximum benefits and to avoid any reaction. 

Can Niacinamide, Vitamin C, and Retinol be applied together?

Not usually… But with Rejuvaus?
YES. Our advanced formulations use encapsulated slow-release Retinaldehyde—a next-gen Vitamin A that’s 500x more potent than traditional retinoids without irritation, peeling, or dryness. Paired with slow-release Vitamin B3, it works gently over 8–12 hours to prevent the classic ‘Niacinamide flare’. 

And for your daily dose of Vitamin C? We skip the harsh acids and use Kakadu Plum, a stable, non-acidic form that absorbs effortlessly and plays well with other actives.

Maximum results, zero compromise.

I use Retinol/ Vitamin A already. Why would I use your serum?

Vitamin A is essential for protecting, repairing, and improving skin. Many formulations, including Retinol and weaker derivatives, can be reactive and irritating, limiting use to a few times a week.

Prescription-strength Retinoic Acid is stronger but often causes redness, dryness, and peeling.

Rejuvaus uses 1% slow-release, encapsulated Retinaldehyde (Retinal), as strong as prescription versions but well-tolerated and more effective. This gradual release over 8 to 12 hours minimises redness, irritation, dryness, and peeling.

Why limit this vital ingredient to a few nights a week when you can use the strongest form of Vitamin A daily? If you are already using a traditional vitmain A we recommend you stop for a few days before starting with the ABC Serum.
