The INKEY List Advanced 0.2% Retinal Serum 0.5 fl oz — Accelerated Renewal, Soothing & Firming

The INKEY List Advanced 0.2% Retinol Serum is a high-strength retinal serum formulated to accelerate skin renewal, visibly smooth lines and improve firmness with minimal irritation.

This serum combines 0.2% encapsulated retinaldehyde with performance boosters to target the five visible signs of aging: wrinkles, loss of firmness, uneven tone, rough texture and dullness. Designed for experienced retinoid users, the formula pairs accelerated cell turnover with soothing and lifting ingredients so you can upgrade your routine while managing sensitivity. It’s fragrance-free, cruelty-free and presented in a 0.5 fl oz bottle for regular nighttime use.

How quickly will I notice smoother lines and wrinkles?

Retinaldehyde is a direct precursor to retinoic acid and is faster acting than standard retinol, so improvements in skin texture and the appearance of deeper lines can appear earlier. Users may observe initial smoothing in as little as one week, with more significant changes over several weeks of consistent use.

• 0.2% encapsulated retinal to increase conversion speed and efficacy
• Accelerated cell turnover encourages visible surface smoothing
• Daily-to-weekly progress depending on skin tolerance and frequency

Will this serum cause irritation, and how is sensitivity managed?

The formula balances potent actives with soothing agents to reduce the likelihood of irritation. Syrelief (a gentle skin-soothing ingredient) helps support the barrier, while the encapsulation of retinal moderates release so skin adapts more comfortably.

• 1.2% Syrelief to calm and support skin barrier resilience
• Encapsulated retinal promotes gradual activity and reduced surface irritation
• Recommended gradual introduction (2–3 nights weekly, increase as tolerated)

What active ingredients make this an anti-aging serum?

This product blends a targeted retinal concentration with actives that lift, firm and soothe. Sirtalice provides an immediate tightening effect while retinal stimulates the renewal processes associated with collagen and elastin support.

• 0.2% retinal (retinaldehyde) for faster cellular conversion than retinol
• 2% Sirtalice for visible lift and smoothing effects within minutes
• Soothing complex to maintain comfort during renewal

How should I add this serum into my skincare routine?

Use this serum in the evening only on clean, dry skin. Start slowly—apply 2–3 nights per week and build frequency as your skin tolerates it. Always follow with a moisturizer and apply broad-spectrum SPF each morning when using retinal products.

• Apply PM only to clean, dry skin; massage gently until absorbed
• Begin 2–3 nights weekly; increase gradually to nightly if tolerated
• Seal with moisturizer; use SPF the next day to protect renewing skin

Who is this for: This serum is intended for people already familiar with retinoids who want a stronger, faster-acting option to address wrinkles, firmness loss, uneven tone and dullness. It’s suitable for all skin types willing to introduce a high-strength retinal with a measured build-up, and for anyone seeking fragrance-free, cruelty-free anti-aging care.
