FAQ:

Q: Is liquid highlighter safe for sensitive skin?

A: These liquid highlighter drops are an actual dream for sensitive skin types. The oil-free formula is derm-approved, allergy-tested, and non-comedogenic, so you can layer it on without risking irritation or breakouts . Turn your face into a pretty little rose quartz with the help of this light-pink liquid highlighter.

Q: What are the best highlighter colors to use?

A: The three colors (icy blue, champagne, and light pink) can look surprisingly low key if you smooth just a couple drops along your cheekbones or eyelids. Considering I’ve had multiple liquid highlighters explode in my bag, I’ll be the first person to tell you not to bring your formula on the go.

Q: Can you use liquid highlighter with liquid foundation?

A: If you’d rather go full-on dewy instead of targeting a few areas of your face, blend a few drops of this highlighter in with your liquid foundation and blend it across your skin. You’ll be left with allover shimmer that looks shockingly natural. If liquid highlighter usually dries you out, you’ll love this moisturizing pick.

Q: How much highlighter do you really need?

A: As someone who doesn’t wear a ton of makeup regularly, I love how truly easy highlighter is. Seriously, all you need are two or three drops of a lightweight, creamy highlighter, and your skin looks infinitely better IMO.
