Dermalogica Dynamic Skin Strengthening Serum, 1 fl oz — Barrier Repair, Peptides & Squalane

Dermalogica Dynamic Skin Strengthening Serum is a concentrated 1 fl oz face serum formulated to fortify the skin barrier, deliver antioxidant protection, and support a more resilient, supple complexion.

This lightweight serum blends Dermalogica’s BioShield technology with biomimetic peptides, upcycled tangerine extract, cotton thistle and squalane to help shore up barrier function while delivering hydration and environmental defense. Designed for daily use under moisturizer and sunscreen, it works to strengthen skin’s bounce-back and help skin appear denser and healthier over time without heavy residue.

How does this serum support my skin barrier?

The formula focuses on barrier resilience by combining ingredients that mimic skin’s natural structures and soothe stressed tissue. These actives help improve the skin’s ability to retain moisture and respond to external stressors, making the surface feel stronger and more comfortable.

• BioShield technology supports barrier integrity.
• Biomimetic peptides help reinforce structural support.
• Cotton thistle and red microalgae contribute calming hydration.
• Squalane restores lipid balance for softer skin.

When and how should I use the Dynamic Skin Strengthening Serum?

Use this serum after cleansing and before your moisturizer, both morning and evening. Apply a few pumps to face and neck with gentle upward strokes; during the day, layer a broad-spectrum SPF as the final step for added protection.

• Dispense 1–2 pumps onto fingertips.
• Spread evenly over face and neck, avoid eye area.
• Follow with moisturizer and daytime SPF when used in the morning.
• Suitable for layering with most skincare treatments.

What active ingredients are inside and what do they do?

The serum combines antioxidant-rich botanicals, lipid-replenishing oils and peptide technology to support skin health. Ingredients are chosen to complement each other—some calm and hydrate, others strengthen and protect against oxidative stress.

• Tangerine extract (upcycled) supplies antioxidant support and brightening precursors.
• Biomimetic peptides promote visible density and resilience.
• Red microalgae and cotton thistle offer hydration and soothing benefits.
• Squalane restores surface lipids and improves skin suppleness.

Can this serum be added to my existing routine without irritation?

Formulated to be compatible with a range of skincare routines, it’s generally well tolerated, but patch-testing is recommended for sensitive skin or when combining with potent actives. If you use strong exfoliants or prescription treatments, introduce the serum slowly and monitor skin’s response.

• Works with most cleansers, moisturizers and serums.
• Patch-test if you have reactive skin or use retinoids/strong acids.
• Layering with SPF in daytime is advised for best protection.
• Avoid direct contact with eyes; discontinue if irritation occurs.

Who is this for: Dermalogica Dynamic Skin Strengthening Serum is intended for anyone looking to reinforce their skin’s barrier, improve hydration retention, and add antioxidant support to their daily routine. It suits dry, combination, and aging-prone skin types that want a lightweight, non-greasy treatment to boost resilience and surface comfort. If your priority is a fortified, more supple complexion while maintaining compatibility with existing actives and SPF, this serum is designed to fit that role.
