Clinically-Proven Cream for Pigmentation and Dark Spots

Crystal Tomato® Skin Clarity Cream is a topical skincare cream for pigmentation and dark spots. A randomised, split-face clinical study by the Skin Research Institute of Singapore (SRIS, A*STAR) evaluated Skin Clarity Cream against Kligman's Formula, and additional independent studies were conducted by Eurofins Dermscan Pharmascan (France) and DeNova Sciences. This page explains how those studies were run, what they found, and what the results mean.

The Study at a Glance

The SRIS (A*STAR) study enrolled 30 participants in a randomised, split-face design over 56 days. Each participant applied Skin Clarity Cream to one side of the face and Kligman's Formula - containing tretinoin 0.05%, hydroquinone 4% and fluocinolone 0.01% - to the other, so each participant served as their own control. Clinical assessments were carried out at Days 14, 28 and 56.

A separate efficacy study at Eurofins Dermscan Pharmascan (France) assessed 29 women aged 47 to 66 (average age 56) over 56 days of twice-daily use at home, with instrumental measurements at Days 14, 28 and 56: skin hydration by Corneometer®, wrinkle depth at the crow's foot by 3D Primos Lite®, skin suppleness by Cutometer®, and skin radiance by spectrophotometer.

Key Finding 1: 47.5% Reduction in Pigmentation by Day 28

In the randomised, split-face study at SRIS (A*STAR), Skin Clarity Cream produced a 47.5% improvement in mean mMASI by Day 28 - a reduction in the assessed area and severity of melasma pigmentation.

What this means: mMASI assesses both the area affected by melasma and its severity. The result describes a change in that clinical score, rather than a percentage change in skin colour.

Proven Brighter, More Luminous Skin

• Clinical trial results demonstrate that Skin Clarity Cream reduced pigmentation by 47.5% at Day 28.

Proven Brighter B&A

• In a separate clinical trial, Skin Clarity Cream showed measurable improvements in skin brightness at Day 28, with further visible reduction in pigmentation and enhanced radiance by Day 56.

Key Finding 2: Comparison with Kligman's Formula

Skin Clarity Cream does not contain hydroquinone, corticosteroids or retinoids. No statistically significant difference in mMASI improvement was observed between Skin Clarity Cream and Kligman's Formula over the 56-day study, supporting the study's conclusion of non-inferior efficacy.

What this means: The split-face design compared the two formulations on opposite sides of each participant's face. Skin Clarity Cream does not contain hydroquinone, corticosteroids or retinoids; its tolerability findings are described separately below.

• Both Skin Clarity Cream and Kligman’s Formula significantly reduced melasma severity from baseline, with improvements seen from Day 14 and maintained through Day 56.

Key Finding 3: Smoother-Looking Wrinkles and Exploratory AGE Findings

Separate efficacy assessments reported visibly smoother wrinkles and a downward trend in skin-aging AGEs (Advanced Glycation End-products). The reported AGE changes did not reach statistical significance at the 0.05 threshold (Day 14: p = 0.09; Day 56: p = 0.10). In user assessments, 82% of participants reported improved suppleness and elasticity, and 78% reported a more even-toned, luminous complexion.

What this means: The wrinkle and user-assessment findings describe changes in skin appearance and perceived skin quality. The AGE findings are exploratory and should not be interpreted as a demonstrated anti-glycation effect.

Visibly Reduces Wrinkles

B&A
  • Clinical assessments reported visibly smoother wrinkle depth over 56 days.

Exploratory: Skin-Aging AGEs

• A downward trend in skin-aging AGEs (Advanced Glycation End-products) was observed from Day 14.

• These changes did not reach statistical significance (Day 14: p=0.09; Day 56: p=0.10) and are exploratory; they should not be interpreted as a demonstrated anti-glycation effect.

Key Finding 4: 40% Increase in Skin Hydration by Day 56

• Clinical trial results demonstrate a 40% increase in skin hydration by day 56, supporting plumper, dewier skin with long-lasting moisture.

User-Reported Results

78% revealed a complexion
that appears more even-toned, luminous and refined.
82% felt their skin regains
its youthful suppleness and elasticity.

*Clinically tested for non-comedogenic and non-acnegenic.

Safety and Tolerability

Skin Clarity Cream was well tolerated in the split-face study, with reported treatment-related irritation assessed as mild. Separate testing also evaluated the formulation for non-comedogenic and non-acnegenic properties. Designed for daily use, the formulation is suitable for sensitive and blemish-prone skin.
