The Spa Dr. Antioxidant Serum — 30 mL Daily Anti-Aging Serum with Bio-Retinol & Hyaluronic Acid, pH-Balanced

The Spa Dr. Antioxidant Serum is a pH-balanced, daily anti-aging serum that combines bio-retinol, resveratrol, hyaluronic acid and Kakadu plum to visibly firm, hydrate, and renew skin with minimal irritation.

This lightweight 30 mL formula is designed as Step 2 in The Spa Dr. 3-Step Age-Defying System and aims to strengthen the skin barrier while delivering antioxidant protection and retinol-like renewal without the usual sensitivity. Clinically tested in-system, the serum pairs a proprietary Skinutriceuticals complex with botanical extracts to improve elasticity, reduce the appearance of fine lines, and support long-term skin health. It’s fragrance-free, non-toxic, EWG Verified, and suitable for daily use across skin types, including sensitive skin.

How does this serum help skin look firmer and smoother?

The formula targets structural and surface signs of aging by combining ingredients that hydrate, promote cellular renewal, and defend against oxidative stress. Over repeated use, the blend supports improved elasticity and the visual softening of fine lines.

• Bio-Retinol mimics retinol benefits while minimizing irritation and flaking.
• Resveratrol supports visible skin resilience and antioxidant defense.
• Hyaluronic Acid draws and holds moisture to plump the skin.
• Kakadu Plum contributes high vitamin C activity to brighten and firm.

Will this serum cause dryness or sensitivity often linked to retinoids?

No — the product is built to reduce the typical retinoid reaction. Bio-Retinol delivers renewal comparable to traditional retinol but is formulated for gentler, daily use, making it a better fit for sensitive or reactive skin when used as directed.

• Designed for daily application without irritation spikes.
• Fragrance-free and calming botanical extracts like aloe and rosemary.
• Clinically tested in the full system for progressive, tolerable results.

How should I include this serum in my routine for best results?

Use it as the nourishing second step after cleansing and before moisturizing. For consistent improvement, apply mornings or evenings as part of The Spa Dr. 3-Step Age-Defying System and follow with sunscreen during daytime routines.

• Step 1: Cleanse and prep skin.
• Step 2: Apply a few drops of serum to face and neck, press gently to absorb.
• Step 3: Seal with moisturizer and SPF during the day.

What evidence supports its anti-aging claims?

Clinical testing of the three-step regimen showed measurable improvements in firmness, elasticity, and wrinkle appearance over consistent use. Ingredient selection focuses on barrier repair and antioxidant protection rather than short-term masking effects.

• 97% of participants saw firmer skin after 28 days in-system.*
• 100% showed elasticity and wrinkle improvements after 56 days in-system.*
• Formulated and tested for long-term skin health; cruelty-free and EWG Verified.

Who is this for? The Spa Dr. Antioxidant Serum is aimed at people seeking visible anti-aging benefits without the common side effects of retinoids — ideal for those with normal, dry, combination, oily, or sensitive skin who want a daily, non-irritating renewal serum. It suits users who prioritize clinically supported, doctor-formulated, fragrance-free skincare and who are building a simple, effective routine focused on barrier repair, hydration, and antioxidant defense.
