The difference between purple and green base creams is mainly the different skin types and skin tones they target.
Purple Barrier is mainly suitable for yellowish skin because of its ability to neutralize yellow for a brighter complexion. If you have a yellowish complexion, using a purple base cream can brighten your complexion and make you look more refreshed.
The Green Base Cream is mainly suitable for reddish skin, as it neutralizes the red color for a more even skin tone. If you have a reddish complexion, using a green base cream can reduce red spots such as redness and rashes for a more natural-looking complexion.
In addition, purple and green barrier creams have different coverage effects. Purple base cream has strong coverage and can cover up some of the deeper blemishes, such as breakouts, scars, etc. Whereas, green base cream has relatively weak coverage and is mainly used to adjust the skin tone and make the skin tone look more even.
When choosing a base cream, it is advisable to choose according to your skin type and skin tone. If you're not sure which color of base cream you should choose, try trying it on your wrist to see which color will better neutralize your skin tone.
In addition, it is important to note that the base cream is only a primer and cannot replace other foundation products such as liquid foundation. After using the base cream, you also need to choose the right base makeup product according to your skin type and needs.
