What is Phyris Time Release Vitamin C Glow Booster?
Phyris Time Release Vitamin C Glow Booster is a silky-soft active-ingredient concentrate from Phyris. Phyris is the German professional skincare brand carried internationally through Dr. Grandel.
The serum also belongs to the Time Release collection. This family of concentrated serums is meant to be layered into a Phyris “Beauty Journey” routine for a specific care goal.
Glow Booster centers on a 10% concentration of pure vitamin C in liposomally encapsulated form. The formula also pairs the vitamin C with ferulic acid. The serum aims for an instant glow, as well as longer-term support for a more even, radiant-looking complexion.
Key benefits of Phyris Vitamin C Glow Booster
- Instant glow: a silky-soft serum formulated to give skin a brighter, more radiant look from the first application.
- More even-looking tone: vitamin C formulated to support the skin’s own collagen synthesis and help balance the look of an uneven complexion over time.
- Softer look of fine lines: ongoing collagen support, designed to help minimize the visible depth of fine lines and wrinkles.
- Antioxidant support: ferulic acid also works alongside the vitamin C to help protect skin’s look against everyday environmental stress.
Key ingredients
Vitamin C (3-O-Ethyl Ascorbic Acid) is a well-known antioxidant. Phyris uses it at a 10% concentration, specifically in liposomally encapsulated form. Phyris positions it as a stimulating co-factor for the skin’s own collagen synthesis. The brand also presents it as a way to help regulate and brighten the look of pigmentation marks.
Ferulic acid, meanwhile, is a plant-derived phenolic compound valued for its antioxidant and brightening properties. Phyris notes it helps protect against everyday environmental stress and also supports a more even-looking tone.
The formula contains fragrance. Phyris also recommends additional daily UV protection alongside this serum.
How to use Phyris Vitamin C Glow Booster
- Cleanse the skin, then apply Phyris Somi as a primer.
- After that, dispense one to two pump doses of Vitamin C Glow Booster into the palm.
- Then smooth over the face, neck and décolleté.
- Let the serum absorb, then continue with the rest of your Beauty Journey routine and a daily SPF.
Who it is for
Glow Booster suits anyone whose skin looks dull, uneven or tired and who wants a lightweight vitamin C step. It can also sit alongside other actives. In addition, Phyris lists it as suitable for every skin type.
However, as with any vitamin C serum, daytime use calls for daily sun protection.
Retail size vs. professional size
This listing is the 30 ml pump bottle, the standard retail size for Glow Booster. A larger 50 ml bottle is also available for those who want more applications between purchases. The formula, however, is identical between the two sizes.
