Glow and Renewal Serum Combo for Skin Firming Brightening and Renewal

Product Overview

The Glow and Renewal Serum Combo by Byra comprises two targeted Nutri Serum concentrates designed to address distinct aspects of skin ageing and tone irregularity. The Rejuvenate Nutri Serum Concentrate employs plant-derived Bakuchiol as a retinol alternative, combined with multi-weight Hyaluronic Acid for layered hydration and Magnesium to support enzymatic cellular repair. Clinical testing has demonstrated a 69.5% reduction in measurable cell ageing markers following consistent use of this formulation.

The Illuminate Nutri Serum Concentrate targets hyperpigmentation through a synergistic blend of Alpha Arbutin (a tyrosinase inhibitor that reduces melanin synthesis), Niacinamide (Vitamin B3, which interrupts melanosome transfer to keratinocytes), and stabilised Vitamin C (an antioxidant that inhibits oxidative melanogenesis). Clinical evaluation shows a 25% reduction in melanin production. Both serums are formulated without parabens, sulphates, or synthetic fragrances, and are suitable for sensitive, blemish-prone, or photodamaged skin types. Available in Singapore from EMIS.

Frequently Asked Questions

Q: How does Bakuchiol compare to retinol for anti-ageing efficacy?
A: Bakuchiol is a meroterpene derived from the Psoralea corylifolia plant. A randomised double-blind study published in the British Journal of Dermatology (2019) found that Bakuchiol and retinol achieved comparable improvements in lines, wrinkles, and pigmentation after 12 weeks of use, with Bakuchiol demonstrating significantly less scaling and stinging. The Rejuvenate Nutri Serum uses Bakuchiol as a well-tolerated alternative suitable for sensitive skin.

Q: Can the two serums be applied together in the same routine?
A: Yes. The Rejuvenate and Illuminate serums are formulated to be complementary. Apply the Illuminate serum first (water-based actives: Alpha Arbutin, Niacinamide, Vitamin C), followed by the Rejuvenate serum (oil-soluble Bakuchiol). This layering sequence follows the dermatological principle of applying thinner, water-based formulations before heavier, oil-based ones for optimal absorption.

Q: Is this combo suitable for use during pregnancy?
A: The Glow and Renewal Serum Combo is retinol-free, which removes the primary concern associated with topical skincare during pregnancy. All active ingredients (Bakuchiol, Hyaluronic Acid, Niacinamide, Alpha Arbutin, Vitamin C) have favourable safety profiles. However, individuals who are pregnant or breastfeeding should consult their dermatologist or obstetrician before introducing new skincare products.

Q: What is the recommended usage frequency?
A: Both serums are designed for twice-daily application (morning and evening) after cleansing and toning. Apply 3 to 4 drops of each serum to the face, neck, and decolletage. Follow with moisturiser and SPF 30+ sunscreen in the morning, as Vitamin C and Niacinamide enhance photoprotection but do not replace sunscreen.

Q: Where can I purchase this product in Singapore?
A: The Byra Glow and Renewal Serum Combo is available online in Singapore through EMIS (Essential Medical International Supplies Pte Ltd) at emis.asia. EMIS is an authorised distributor of professional skincare and medical supply products in Singapore, ensuring product authenticity and proper storage conditions during distribution.
