Glutathione vs Vitamin C Serum: Which One Should You Use?
Share
Glutathione and vitamin C are two of the most searched-for ingredients for a brighter, more even look. Both are antioxidants, both are popular in serums, and many people wonder whether they need one, the other, or both. Here is a simple way to decide.
What is glutathione serum?
Glutathione is an antioxidant used in skincare for a brighter, more even-looking complexion. The Theraglow Glutathione Serum is a 30ml serum that combines glutathione with guava and papaya extracts, plus hyaluronic acid and glycerin for hydration and saxifraga extract for luminosity. It has a lightweight texture and is designed to be applied to damp skin.
What is vitamin C serum?
Vitamin C is one of the best-known brightening antioxidants. The Brightfix C-Serum uses orange and lemon extracts rich in vitamin C, with essential oils for a soft feel. It is made to target the look of dark spots and pigmentation and to even out skin tone, and it is meant for daily use.
The quick comparison
| Glutathione serum | Vitamin C serum | |
|---|---|---|
| Main goal | Even, radiant look plus hydration | Brightness and the look of dark spots |
| Theraglam serum | Theraglow (glutathione, guava, papaya, hyaluronic acid) | Brightfix (orange and lemon extracts) |
| Texture | Lightweight, hydrating | Light, absorbs with massage |
| Best for | Dull skin that also feels dry or tight | Dullness, uneven tone and spots |
Which one should you choose?
- Your skin looks dull and feels dry: start with glutathione serum. The hyaluronic acid and glycerin in Theraglow add hydration as well.
- Your main concern is dark spots or uneven tone: start with vitamin C serum.
- You are new to serums: pick one, use it for four weeks, and judge it before adding a second.
Can you use both?
Yes, many people do. The simplest way is to split them across the day:
- Morning: cleanse, Brightfix C-Serum, moisturiser, sunscreen.
- Night: cleanse, Theraglow Glutathione Serum on damp skin, night cream.
Splitting them keeps each routine short and lets each serum absorb on its own. If you prefer to layer them together, apply the thinner one first and wait a minute before the next.
How to apply a serum
- Cleanse and gently pat your face, leaving it slightly damp.
- Put two to four drops on your fingertips.
- Press and massage into the face and neck in gentle circles until absorbed.
- Follow with moisturiser. In the morning, always finish with sunscreen.
Mistakes to avoid
- Starting two new serums at once. If your skin reacts, you will not know which one caused it.
- Skipping sunscreen. Any brightening routine works best with daily sun protection.
- Expecting overnight change. Give a serum about four weeks of regular use.
