Boticário Cuide-se Bem Melancia Overnight Facial Mask – Watermelon Leave-On Care – 1.76 oz (50 g)
- Acts as a leave-on gel mask applied at night and rinsed off the next morning.
- Uses glycolic acid and lactic acid (AHAs) to help skin look smoother and more even in texture.
- Helps skin feel hydrated and comfortable thanks to sodium hyaluronate and propanediol.
- Adds the Cuide-se Bem Melancia fragrance to the evening skincare step as a sensory ritual.
- Comes with an AHA routine requirement: daily sunscreen and limited sun exposure.
Made for adults (18+) who want to add a gentle exfoliating acid step to their evening routine and who enjoy a sweet, fruity fragrance, and who are willing to wear sunscreen every day while using it. It is not for children, not for the eye area or eyelids, and not for irritated or broken skin. It is a poor fit for anyone sensitive to fragrance or to the labelled fragrance allergens (Hexyl Cinnamal, Limonene, Linalool), for anyone who avoids synthetic color additives, and for anyone already layering other exfoliating acids or retinoids at night without professional guidance.

- 1.76 oz (50 g) jar, limited edition, packaged in recycled plastic.
- Key ingredients: glycolic acid and lactic acid (AHAs), sodium hyaluronate, propanediol.
- Made in Brazil by O Boticario, the country's largest beauty franchise, founded in 1977 in Curitiba.
- Bouncy, jelly-like pink gel that stays in place overnight and washes off in the morning.
- Vegan, certified cruelty-free, 91% naturally derived ingredients, free of parabens, silicones and petrolatum.
At night, apply a small amount over the whole clean face using upward motions for better absorption. Avoid the eye area and eyelids, the outer corners of the nose and mouth, and any irritated or broken skin. Do not remove the product: leave it on overnight. In the morning, wash your face and apply a broad-spectrum sunscreen of at least SPF 30. During the first week of use, apply small amounts on alternate days before moving to more frequent use.
- Wide screw-top jar: use clean fingertips or a clean spatula, and keep it tightly closed, away from light and excessive heat.
- The gel is intensely pink from synthetic color additives (tartrazine, Red 33 and Brilliant Blue), so treat it as potentially staining on light pillowcases and towels; the label marks it for adult use (18+), says to keep it out of reach of children, and warns that temporary stinging, tingling or dryness can appear in the first applications.
- Contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn: use a sunscreen, wear protective clothing and limit sun exposure while using this product and for a week afterwards, and discontinue use if irritation occurs.
The formula is built around one overnight acid step: glycolic and lactic acid work on the skin's surface during the hours the mask is left on, while sodium hyaluronate and propanediol hold water at the surface so skin feels comfortable rather than tight, and acacia senegal gum and xanthan gum give the gel enough body to stay where it is applied instead of sliding off. Sodium hydroxide and the sodium phosphates keep the pH in a skin-friendly range, and phenoxyethanol with hydroxyacetophenone preserve a water-rich jar product. Because the acids do their part overnight, the morning half of the routine carries equal weight: cleanse, then apply a broad-spectrum sunscreen of at least SPF 30, exactly as the label instructs, and keep sun exposure limited while using the mask and for a week afterwards.

Learn moreMeet the Cuide-se Bem Melancia Overnight Facial Mask – 1.76 oz (50 g), a limited-edition leave-on gel mask from O Boticário, the beauty house Brazilians have trusted since 1977. It is the last step of your evening routine: you smooth it on, leave it on, and rinse it off the next morning.
Made in Brazil and shipped worldwide by MKPBR, this jelly-textured mask pairs glycolic acid with sodium hyaluronate, so skin looks smoother and feels more comfortable and hydrated by morning. Its juicy watermelon-inspired scent is fragrance only — there is no watermelon extract in the formula.
Important: this mask contains an alpha hydroxy acid (AHA), so daytime sun protection is part of the routine. Please read the Sunburn Alert and the label warnings below before your first use. Developed for adult skin (18+).
Key Features:
- Overnight leave-on gel mask: applied at night over the whole face and left on until morning — no rinsing before bed.
- Glycolic acid (AHA) plus lactic acid: alpha hydroxy acids that help refine the look and feel of skin texture, so skin appears smoother and more refreshed. Because they are AHAs, sunscreen and limited sun exposure are required during use and for a week afterwards.
- Sodium hyaluronate: a humectant that helps skin hold water, so it feels softer and looks plumper.
- Watermelon-inspired fragrance: a sweet, energizing scent that is part of the sensory ritual — a fragrance note, not an active ingredient.
- Gradual introduction, by the label: during the first week, use small amounts on alternate days, then build up as your skin adapts.
- Vegan, cruelty-free and 91% naturally derived ingredients: free of parabens, silicones and petrolatum, in a jar made with recycled plastic.
- Limited edition, made in Brazil: part of the Cuide-se Bem Melancia capsule, one of the most requested scents in the line.
How To Use
- At night, cleanse your face and pat it dry.
- Scoop a small amount and apply over the entire face using upward motions for better absorption.
- Avoid the eye area and eyelids, the outer corners of the nose and mouth, and any irritated or broken skin.
- Do not remove the product — leave the mask on overnight.
- In the morning, wash your face and apply a broad-spectrum sunscreen of at least SPF 30, and reapply it through the day.
- For the first week of use, apply small amounts on alternate days before moving to more frequent use.
Expert Tip: keep the jar clean and dry, use a clean spatula or clean fingertips, and pair the mask with a gentle, non-abrasive cleanser — skip scrubs and other exfoliating acids on the same night.
Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn.

Ingredients (Highlights)
- Glycolic Acid – the alpha hydroxy acid at the heart of the formula; it works on the surface of the skin overnight so texture looks smoother and more even. It is also what makes daily sunscreen non-negotiable.
- Lactic Acid – a second, gentler alpha hydroxy acid that supports the same surface renewal and helps keep the formula at a skin-friendly pH.
- Sodium Hyaluronate – a lightweight form of hyaluronic acid that draws water into the upper layers of the skin, so skin feels cushioned rather than tight after the acids.
- Propanediol – a plant-derived humectant and solvent that keeps the gel fluid and helps the other ingredients spread evenly.
- Acacia Senegal Gum & Xanthan Gum – natural gums that give the mask its bouncy, jelly-like body so it stays put on the face all night.
- Parfum – the watermelon-inspired scent. It contains the labelled fragrance allergens Hexyl Cinnamal, Limonene and Linalool.

FAQ
Do I rinse this mask off before going to bed?
No. This is a leave-on overnight mask: you apply it at night, leave it on, and wash your face the following morning.
I have never used an acid product before. How do I start?
Follow the label: during the first week, apply a small amount on alternate days, then increase frequency as your skin adapts. Patch test first, and stop if irritation appears.
Why do I need sunscreen with this mask if I use it at night?
Because it contains an alpha hydroxy acid, which can make your skin more sensitive to the sun. Wear sunscreen and limit sun exposure while you are using it and for a week after you stop.
Does it actually contain watermelon?
The watermelon is the scent and the theme of this limited edition, not an active. The full INCI list above shows exactly what is inside.
Is the packaging in Portuguese?
Yes. This is the authentic Brazilian product, so the jar and label are printed in Portuguese. The English usage steps, ingredient list and warnings on this page follow the original label.
