The Anti-Ageing Ingredient Showdown
Walk into any skincare aisle in Australia and you’ll be bombarded with promises: “reverse ageing,” “turn back time,” “look 10 years younger.” But behind the marketing hype are three powerhouse ingredients that actually have science on their side — sheep placenta, retinol, and collagen. So which one deserves a spot in your skincare routine?
Sheep Placenta: Nature’s Reset Button
Sheep (ovine) placenta extract has been used in skincare for decades, particularly in Australia and New Zealand where the sheep industry is world-renowned. What makes it special?
Placenta extract is packed with growth factors, amino acids, vitamins, and antioxidants. These nutrients work together to promote cell regeneration, improve skin elasticity, and enhance overall skin texture. Research published in the journal Processes (MDPI, 2022) confirmed that sheep placenta extract demonstrates significant anti-aging effects, including improved fatigue recovery and cellular rejuvenation.
Best for: People looking for a natural, gentle approach to anti-ageing. Sheep placenta is particularly well-suited for sensitive skin types that may not tolerate harsher actives.
Retinol: The Gold Standard
Retinol (Vitamin A derivative) has been the dermatologist’s go-to anti-ageing ingredient for over 30 years. And for good reason — it has the most robust clinical evidence behind it.
Retinol works by accelerating cell turnover, stimulating collagen production, and reducing the appearance of fine lines and wrinkles. It’s been proven effective for treating acne, hyperpigmentation, and sun damage — making it a true all-rounder.
Best for: Those who want clinically proven results and don’t mind the adjustment period. Retinol can cause dryness, peeling, and sun sensitivity, so it requires careful introduction into your routine.
Collagen: The Building Block
Collagen is the most abundant protein in your skin, responsible for keeping it firm and plump. As we age, our natural collagen production declines by about 1% per year after age 25.
Topical collagen products aim to replenish what’s been lost, though there’s ongoing debate about whether applied collagen can penetrate the skin effectively. Newer formulations use hydrolysed collagen (smaller molecules) and peptide technology to improve absorption.
Best for: Preventative care and maintaining skin hydration. Collagen works best when combined with other actives rather than used alone.
Can You Use Them Together?
Absolutely — and many skincare experts recommend it. Here’s a smart combination approach:
- Morning: Collagen serum + SPF for protection and hydration
- Evening: Retinol (2-3 times per week) OR sheep placenta (on alternate nights)
Sheep placenta’s gentle nature makes it an excellent complement to retinol, as it can help soothe the irritation that retinol sometimes causes.
The Bottom Line
There’s no single “best” anti-ageing ingredient — the right choice depends on your skin type, concerns, and tolerance. At Rebirth, we believe in harnessing the power of sheep placenta as a cornerstone ingredient, and our range is designed to work beautifully alongside your existing routine.
