Clinical Report for Mamaearth Rice Dewy Bright Face Wash-
Mamaearth Rice Dewy Bright Face Wash: Clinical Testing and Efficacy Guide
Quick answer: Mamaearth Rice Dewy Bright Face Wash was tested in a clinical study on 36 human volunteers at Mascot Spincontrol Clinical Research Centres. This is an immediate-effect study measuring a single wash at two timepoints. Corneometer measurement recorded a 47.88% increase in skin moisturisation at 30 minutes, still 26.62% above baseline at 2 hours. Dermatological assessment recorded an 18.86% improvement in skin even tone at 30 minutes and 10.96% at 2 hours. Every parameter peaks at 30 minutes and settles by 2 hours, which is the expected profile for a rinse-off cleanser.

Why both timepoints are published
Every measured parameter peaks at 30 minutes and remains elevated at 2 hours - the expected profile for an immediate effect from a rinse-off product. Both timepoints appear throughout this page so the full picture is visible: what you see straight after washing, and what is still there two hours later.

Frequently Asked Questions
Questions below reflect what people in India actually search. Search demand from Ahrefs, September 2026.
A: 94% of the 36 volunteers reported a glowing, glass-like finish within 2 hours of a single wash. “Glass skin” is a consumer descriptor, which is why it sits in the reported section, and the objective measurements alongside it are a 47.88% rise in skin moisturisation at 30 minutes and a 2.09% increase in chromameter-measured brightness.
A: The study measured a single wash at 30 minutes and 2 hours. Moisturisation was 47.88% above baseline at 30 minutes and still 26.62% above at 2 hours. This is a same-day cosmetic effect, not a treatment that builds over weeks.
A: This study did not test that, and a rinse-off cleanser is not the right format for it. Niacinamide has good published evidence for pigmentation, but from leave-on products used across several weeks. For dark spots, use a leave-on serum and daily sunscreen, and see a dermatologist if the pigmentation is persistent or spreading.
A: It is a creamy, soap-based cleanser with glycerin, sodium PCA, glyceryl glucoside and propylene glycol as humectants, and corneometer measurement showed hydration rising 47.88% at 30 minutes. Volunteers reported no tightness or irritation. If your skin is very dry, follow immediately with a moisturiser on damp skin.
A: Yes. No irritation was reported by the 36-person panel. Morning and night is normal for a cleanser. If your skin feels tight, cut back to once daily in the evening.
A: The study measured 30 minutes and 2 hours, and the effect is strongest soon after washing and still clearly present at two hours. This is the immediate glow a cleanser gives; leave-on products carry it through the rest of the day.
A: Yes. Cleanser first, then serum on clean skin, then moisturiser, then sunscreen in the morning. This cleanser contains niacinamide, and since it is rinsed off, a leave-on niacinamide serum pairs well with it rather than duplicating it.
A: It is a cleanser suitable for all skin types, and volunteers reported no irritation. If breakouts and oiliness are your main concern, the Tea Tree Face Wash was tested on exactly those endpoints and may be the better match.
A: This one was tested for immediate glow, hydration and even tone from a single wash. Vitamin C targets dullness and brightening; Ubtan targets tan removal. Choose by concern: instant glow before an event or in the morning points to this one.
A: Both. Fermented rice water appears high in the ingredient list, and Oryza sativa rice extract appears further down alongside niacinamide.
A: It contains no retinoids or high-strength acids. As with anything in pregnancy, your doctor can confirm what suits you, since they know your history.
A: Yes - it is a standard panel size for cosmetic efficacy work, and comfortably sufficient for detecting immediate instrumental change across two instruments plus dermatological and expert assessment. Longer-term endpoints are the domain of longer studies, which is why this one focuses on the immediate effect it set out to measure.
People Also Ask
High-volume questions people in India search in this category. Search volumes from Ahrefs, September 2026.
Glass skin describes skin that looks smooth, even and hydrated enough to reflect light, and it comes from hydration, an intact barrier and even texture. In a clinical study on 36 volunteers, 94% reported a glowing, glass-like finish within 2 hours of a single wash with this face wash, and corneometer-measured moisturisation rose 47.88% at 30 minutes. That is the same-day version; the lasting one comes from keeping the hydration, sunscreen and sleep consistent.
Four habits do most of the work: cleanse gently, moisturise while skin is still damp, wear sunscreen daily, and sleep. Dullness usually comes down to hydration, dead cell buildup and sun exposure. This face wash was measured on the first of those - moisturisation +47.88% at 30 minutes and +26.62% at 2 hours after a single wash.
One that leaves skin comfortable rather than tight, since hydration is what glow is made of. Measured hydration is a more useful signal than the word “glow” on the pack. In this study, hydration, even tone, smoothness, brightness and luminosity were all measured by instrument or dermatologist at 30 minutes and 2 hours, and all five improved.
Glow, very much so. Seven days of gentle cleansing, hydration and daily sunscreen makes a visible difference, because glow comes from hydration and texture - both of which respond quickly. Your underlying skin tone is set by genetics and stays yours. This study measured a 2.09% increase in chromameter brightness, which reflects how much light the skin surface returns once dullness is cleared.
The routine underneath the trend is layered hydration and barrier care: gentle cleansing, humectants applied to damp skin, an occlusive to seal, and daily sunscreen. A cleanser is the first step, and this one is formulated with glycerin, sodium PCA and glyceryl glucoside so it hydrates while it cleanses.
Adequate water, enough protein, and a diet with fruit, vegetables and omega-3 sources. Glow comes from the overall pattern rather than any single food - and staying well hydrated, eating enough and sleeping properly is what shows up most visibly in skin.
A creamy, hydrating one. This is a creamy cleanser containing glycerin, sodium PCA, glyceryl glucoside and propylene glycol as humectants, and 36 volunteers reported no tightness or irritation. If your skin is very dry, follow immediately with moisturiser on damp skin.
Yes, for inflammation and post-acne marks, at around 4–5% in a leave-on product used over weeks. This face wash contains niacinamide, and since it is rinsed off, a leave-on serum pairs well with it if acne or pigmentation is your goal.
