Grospe Glutathione Serum 20000ppm 1 fl oz — Korean brightening ampoule with hyaluronic acid for hydration and reduced dark spots

Grospe Glutathione Serum is a high-strength Korean ampoule that blends 20000ppm glutathione with hyaluronic acid to hydrate skin, reduce the look of dark spots, and improve elasticity.

This lightweight 1 fl oz serum absorbs rapidly and pairs a potent antioxidant (glutathione) with moisture-binding hyaluronic acid and supportive actives to help even skin tone and plump fine lines. Formulated for everyday use and packaged with a dropper for precise application, the formula aims to nourish skin, help minimize visible hyperpigmentation, and leave a dewy finish without heavy residue. The product dimensions are compact (1.6" x 1.6" x 3.5") and the serum has a 3-year shelf life.

How does this serum address dark spots and uneven tone?

The serum leverages a concentrated glutathione extract to target discoloration pathways and support an overall brighter complexion. Regular use can help reduce the appearance of hyperpigmentation while supporting skin’s natural repair processes.

• Contains 20000ppm glutathione for targeted antioxidant support.
• Includes complementary actives like ascorbic acid and arginine to enhance clarity.
• Lightweight ampoule texture encourages daily layering under moisturizers.

Will it help with hydration and fine lines?

Hyaluronic acid in the formula attracts and locks in moisture, creating a plumping effect that softens the look of fine lines. This boosts surface elasticity and gives skin a smoother, more supple appearance without feeling greasy.

• Multi-weight hyaluronic acids for immediate and lasting hydration.
• Fast-absorbing base that layers well with other skincare steps.
• Leaves a natural dewy finish ideal for dry or combination skin.

How should I use the Grospe Glutathione Serum in my routine?

Apply the serum after cleansing and toning but before heavier creams and oils to maximize absorption. Use the dropper to dispense 2–3 drops and gently press into face and neck; follow with moisturizer and SPF in the daytime.

• Morning and evening use recommended for consistent improvement.
• Pair with sunscreen daily to protect treated areas from further pigmentation.
• Patch-test if you have very sensitive skin or are using other active ingredients.

What results can I expect and how long until I see them?

Visible results vary by individual, skin type, and prior sun damage. Many users notice improved hydration and a softer skin texture within days, while reductions in dark spots and more even tone typically develop with consistent use over several weeks.

• Immediate: increased surface hydration and a luminous finish.
• 4–8 weeks: gradual evening of skin tone and softer fine lines with routine use.
• Best results when combined with sun protection and gentle exfoliation.

Who is this for: Grospe Glutathione Serum is intended for anyone seeking brighter, more hydrated skin—especially people concerned about hyperpigmentation, early signs of aging, or dullness. It suits all skin types, including dry and combination skin, and works well layered under moisturizers and makeup. Avoid combining with incompatible strong actives without consulting patch testing; discontinue if irritation occurs.
