What it is
PPG-55 Glyceryl Ether is a synthetic compound made by reacting propylene oxide with glycerin. It belongs to a family of ingredients called glyceryl ethers, which are known for their ability to hold water and improve the feel of skincare products.
How it works
It works by attracting water molecules from the environment or deeper layers of the skin to the surface, keeping the skin hydrated. It also reduces the surface tension of other ingredients, helping them spread more easily and absorb more effectively.
Pros
Lightweight hydration
Provides moisture without the heavy, sticky feel of some other humectants, making it ideal for daytime use or under makeup.
Boosts ingredient absorption
Helps other active ingredients in your routine penetrate more effectively, so you get more benefit from your serums and treatments.
Cons and cautions
Synthetic origin
It is lab-created, which may be a turn-off for people who prefer naturally derived ingredients in their skincare.
Potential tackiness at high levels
In very high concentrations, it can leave a slightly sticky or tacky feel on the skin, though this is rare in well-formulated products.
Best for
- Anyone looking for a lightweight, non-greasy moisturizer
- People with normal to combination skin who want better product absorption
Use caution if
- Those who strictly avoid synthetic ingredients in their skincare
