Glutathione + Alpha Arbutin Serum: A Simple Guide to an Even, Hydrated Glow
tuskee Team · 19 October 2026

Dark spots, sun tan and uneven tone are among the most common skin concerns, especially in Indian weather. The tuskee Glutathione Super Hydro Illumination Face Serum brings together L-Glutathione, Alpha Arbutin and Sodium Hyaluronate. This guide explains what each one does and how to use the serum for a clearer, hydrated look.

What is Glutathione?
Glutathione is a small molecule that our bodies make naturally, and it is known as a master antioxidant. In skincare it is used to help protect skin from free radicals caused by pollution, UV exposure and blue light. These free radicals are one of the reasons skin looks dull and develops dark patches over time. Glutathione supports a lighter, more uniform-looking skin tone.
What is Alpha Arbutin?
Alpha Arbutin is a plant-derived brightening ingredient. It helps slow down the look of excess pigment, which is why it is popular for sun spots and the marks left after breakouts. It is a gentle option, which is why it is used widely in daily serums.

Why the two work well together
Brightening ingredients work in different ways. Glutathione acts as an antioxidant that supports even-looking tone, while Alpha Arbutin targets the look of dark spots. Using two actives together gives your skin help from two angles, so the effect looks more even than using either one on its own.
Why Sodium Hyaluronate matters
Brightening should not leave skin dry. Sodium Hyaluronate holds water in the skin, giving a plump, bouncy and soft finish. Well-hydrated skin also reflects light better, so it naturally looks more luminous.

How to use the serum
- Cleanse your face and pat dry.
- Place 2 to 3 drops on your fingertips or face.
- Press and smooth over the face and neck. Let it dry down for about 45 seconds.
- Apply an oil-free moisturiser.
- In the morning, always follow with a broad-spectrum SPF 30+ sunscreen.

Sun protection is part of the routine
If you are working on the look of dark spots or tan, sunscreen is not optional. Sunlight is the main reason spots come back. Use sunscreen every morning and reapply when you are outdoors for long.
Pairing with other products
This serum layers easily. Use it before your moisturiser. If you like a brightening routine, you can use Vitamin C such as our Vit C+E serum in the morning and this serum at night, or the other way around. If you use an exfoliating acid, keep it for a separate night.
Tips
- Be consistent. A small amount used every day works better than a lot used now and then.
- Do a patch test on the inner arm first.
- Store in a cool, dry place with the cap closed tightly.
- Take a photo every two weeks in the same light. It is the easiest way to see gradual change.
Who should try it?
If you have sun tan, dark spots, post-acne marks or a dull, uneven tone, this serum is made for you. It is water-light, oil-free and suitable for all skin types.

What to expect, week by week
- Week 1 to 2: skin often feels more hydrated and looks fresher, thanks to Sodium Hyaluronate.
- Week 3 to 4: skin looks more even in tone and less dull as the antioxidants and brightening actives start to work.
- Week 6 to 8: the look of dark spots, tan and post-acne marks is softer, if you use the serum regularly and protect your skin from the sun.
These are general timelines, and every skin is different. The two things that make the biggest difference are consistency and sunscreen. Without sunscreen, the sun can bring back the marks you are working on.
