Peter Thomas Roth Retinol Fusion PM Night Serum — 1.5% Microencapsulated Retinol, Hydrating Night Treatment for Fine Lines & Radia

Peter Thomas Roth Retinol Fusion PM Night Serum is a time‑released, hydrating 1.5% microencapsulated retinol formula designed to improve fine lines, wrinkles, skin texture and uneven tone while you sleep.

This lightweight night serum releases retinol gradually to minimize irritation while delivering consistent corrective activity overnight. Formulated with microencapsulated retinol for controlled delivery and boosted with Vitamins C and E for antioxidant support, it aims to refine surface texture, brighten dullness and improve overall radiance without stripping moisture. The non-greasy, moisturizing base makes it suitable for a wide range of skin types and evening regimens.

How does microencapsulated retinol differ from regular retinol?

Microencapsulation surrounds retinol molecules with a tiny protective coating that releases the active ingredient slowly. This controlled release reduces sudden exposure, which can help lower irritation and dryness common with immediate‑release retinol products.

• 1.5% concentration provides a potent dose tuned for nighttime use
• Time‑release delivery sustains activity across several hours
• Reduced peak exposure lowers redness and sensitivity risk
• Encapsulation helps stabilize retinol for longer shelf life

Will this serum hydrate while treating signs of aging?

Yes — the formula pairs active retinol with moisturizing ingredients and antioxidant vitamins. Instead of a drying, harsh finish, it’s designed to support the skin barrier and lock in hydration so treatment and comfort go together.

• Moisturizing base prevents excessive flaking or tightness
• Vitamins C and E deliver antioxidant protection and skin brightening
• Non‑greasy texture layers easily under creams or oils
• Suitable for use in most nightly skincare routines

How should I introduce this into my routine to avoid irritation?

Begin gradually: start with every other night or a few times weekly, then increase frequency as tolerance builds. Always apply to clean, dry skin at night and use sunscreen daily, since retinol can increase sun sensitivity.

• Patch test before full face application
• Begin using 2–3 nights per week, then progress as tolerated
• Pair with a moisturizer if dryness appears
• Use broad‑spectrum SPF each morning while using retinol

What improvements can I expect and when?

Visible improvements depend on skin condition and consistency, but many users see smoother texture and enhanced radiance within several weeks. More significant reductions in fine lines and uneven tone typically develop with continued use over months.

• Initial smoothing and brightness often in weeks
• Texture refinement and pore appearance over 4–8 weeks
• Progressive reduction in fine lines with ongoing use
• Results improve when combined with sun protection and gentle exfoliation

Who is this for: This serum is intended for adults seeking an effective nighttime retinol treatment that balances potency with gentler delivery. It suits those targeting early to moderate signs of aging, uneven tone or texture, and anyone wanting antioxidant support alongside retinol. If you have very sensitive skin, active dermatitis, or are pregnant or breastfeeding, consult a dermatologist before use.
