TONE EVENING
PEARfect Tone® is a high-tech biomimetic active designed to support the skin under multispectral light exposure — UV, visible and infrared — helping maintain tone stability and a more balanced post-exposure response.
Inspired by the adaptive physiology of the Xuehua pear, it is obtained through a refined eco-designed process that concentrates the most relevant bioactive fractions while preserving their functional integrity. This results in a balanced phytocomplex that helps modulate key photobiological pathways.
By moderating early pigment activation, supporting heat- and IR-related stress responses, and enhancing tolerance to UV exposure, PEARfect Tone® promotes a more uniform, stable and photoresilient complexion.
EFFICACY TESTS
Heat & IR Protection — HSP72 Modulation
Setup:
Keratinocytes exposed to IR light + heat (850 nm, 42°C). PEARfect Tone® tested at three concentrations. HSP72 quantified as stress marker.
Interpretation:
Significant reduction of HSP72 overexpression (up to –46%), indicating improved protein homeostasis and lower stress accumulation under infrared exposure.
Melanin Control — Tyrosinase Activity
Setup:
Tyrosinase quantified via colorimetric assay (510 nm) to assess early melanogenesis activation.
Interpretation:
Marked inhibition of tyrosinase activity (–26% to –12%), supporting early-stage tone preservation under UV stress.
Melanin Reduction — 3D Reconstructed Epidermis
Setup:
3D epidermis irradiated with UVA/UVB; melanin quantified after treatment with PEARfect Tone®.
Interpretation:
Strong reduction of UV-induced melanin accumulation (up to –68%), restoring values closer to baseline.
UV Tolerance — Minimal Erythema Dose (MED)
Setup:
28-day split-back study (22 volunteers). Daily application of 5% PEARfect Tone® and controlled UV exposures using a solar simulator.
Interpretation:
Significant increase in MED (+24.5%), indicating enhanced biological tolerance and reduced redness reactivity.
Clinical Self-Assessment
Setup:
Same 28-day protocol under UV challenge. Volunteers evaluated radiance, evenness, moisture, redness response and heat-related comfort.
Interpretation:
Consistent perceived improvements: more radiant, even, comfortable and less reactive skin after sun exposure — confirming instrumental data.

PROPERTIES
Multispectral Photoadaptation
Supports the skin’s adaptive response to UV, visible and infrared exposure, contributing to a calmer and more controlled post-exposure profile.
Tone Stability & Pigment Balance
Helps maintain a uniform complexion by supporting early-stage pigment regulation and minimizing chromatic fluctuations linked to light-induced stress.
Phototolerance Reinforcement
Contributes to improved resilience under repeated UV exposure, aligning with more stable erythema thresholds and a less reactive skin response.
Heat & IR Stress Modulation
Helps the skin manage biomolecular stress signals induced by thermal and infrared exposure, promoting a more balanced physiological response.
High-Tech & Safe
Refined biomimetic active obtained through an eco-designed process that preserves functional bioactive fractions; clean profile and easy integration into modern daily-defense and sunscreen-adjacent formulations.
