PEARfect Tone®
BIOMIMETIC UV LIGHT PROTECTION FOR SKIN BRIGHTENING & TONE EVENING
INCI
Glycerin, Pyrus Communis (Pear) fruit extract
UV DEFENCE
TONE EVENING
Melanin Control
Photoaging, also known as sun damage, is caused by prolonged UV radiation exposure which accelerates skin aging beyond its natural course. All skin types are vulnerable to photoaging. Following a biomimetic approach and imitating pear’s complex defense system to fight the harmful effects of UV radiation, PEARfect Tone®, a skin-brightening ingredient, has been designed to target dark spots and uneven skin tone. Its key component, Pyrus communis extract, is derived from the Xuehua pear, known for its high content of arbutin and flavonoids. The extract is enriched in active ingredients through ultrasound-assisted extraction and tangential flow filtration. Dihydromyricetin, a powerful flavonoid UV absorber, inhibits tyrosinase, the enzyme responsible for melanin synthesis. Additionally, arbutin contributes to skin-lightening effects on hyperpigmentation while promoting wound healing and supporting collagen production.
According to the literature, the active ingredient is expected to be biodegradable, non-irritating, and environmentally safe for aquatic ecosystems. These properties align with its chemical structure and natural origin, supporting its sustainability profile.
UV RADIATION IMPACT ON SKIN
- Accelerates skin aging of the most exposed areas affecting all skin types.
- Leads to hyperpigmentation, texture changes, loss of elasticity, wrinkles, and redness by stimulating melanin production.
- Treatments can reduce signs of photodamage without fully erasing them.
PYRUS COMMUNIS STRATEGIES
- Has evolved complex defenses producing protective molecules that act as natural sunscreens.
- Accumulates flavonoids in the skin to block UV rays and the waxy cuticle reflects sunlight.
- Combines biochemical, structural, and molecular strategies to protect from UV damage, supporting both survival and growth.

- Treatments can reduce signs of photodamage without fully erasing them.
Hair and scalp protection from UV radiations
Flavonoids are powerful antioxidants also for hair.
They have been shown to play a protective role in maintaining hair health by protecting it from UV-induced damage (Cižmárová B. et al., 2023; Bassino E. et al., 2020).
Flavonoids can reach the hair cortex, inhibit the formation of hair-derived radicals upon irradiation, and protect internal hair structures from oxidation thereby preserving the structural integrity of hair and preventing premature degradation (Dario M.F. et al., 2020).
EFFICACY TESTS
HYPERPIGMENTATION INHIBITION
PEARfect Tone®, in human epidermis, significantly (p<0.05) reduces melanin production after UV exposure in a dose dependent manner (Graph 1) and its activity is driven by the tyrosinase inhibition whom enzymatic activity, responsible of melanin synthesis, has been inhibited after 1 hour treatment at any concentrations tested (graph 2). Pictures of melanin production in human epidermidis (represented by brown color intensity) after UV exposure and PEARfect Tone® treatment are shown for each samples. The browner the epitelium becomes, the more melanin and radiation-induced damage increase.

PROPERTIES
- UV Protection: PEARfect Tone® contains dihydromyricetin, a UV-absorbing flavonoid, and arbutin, providing natural protection against UV-induced damage and reducing hyperpigmentation.
- Hyperpigmentation Inhibition: Effectively reduces melanin production in human epidermis models exposed to UV radiation by inhibiting tyrosinase enzymatic activity.
- Biomimetic Approach: Inspired by Pyrus communis’ natural UV defense mechanisms, it replicates the pear’s strategy of combining antioxidants and protective molecules to shield the skin.
- Eco-Friendly Profile: PEARfect Tone® is biodegradable, non-irritating, and safe for aquatic ecosystems, aligning with sustainability principles
