Our take on the RMS Beauty Straight Up Volumizing Peptide Mascara Blackest Black

Straight Up is a peptide-enriched volumizing and lengthening mascara in a deep black shade, built around a clean formula rather than dramatic false-lash volume. It suits shoppers who want a natural, separated lash look with conditioning ingredients and a gluten-free formula. Against drugstore volumizers it offers cleaner ingredients and a lighter feel, but it builds volume more slowly and some users find the wear shorter than long-wear rivals.

Questions and answers

Is this mascara good for sensitive eyes or contact lens wearers?
The formula is gluten-free and built around nourishing ingredients, which many sensitive-eye shoppers prefer. It is not marketed as ophthalmologist-tested, so patch test or check with your eye doctor if you react easily.
Does it give dramatic volume?
No. It builds moderate, natural-looking volume in layers. Shoppers wanting a false-lash effect should look at fiber or tubing mascaras instead.
How does it compare with RMS Beauty's other mascaras?
Straight Up focuses on peptides and a clean volumizing formula with a natural finish. Check the brush and finish of RMS's other mascaras if you want more curl or a drier formula.
Will it smudge on oily lids?
Some users with oily lids report smudging late in the day. A light setting powder around the eyes and a thin first coat can help.
Is it easy to remove?
It comes off with warm water and regular cleanser for most users. Waterproof makeup removers are not usually needed.
What is in the tube?
One mascara tube with an applicator brush in the Blackest Black shade, 0.338 fl oz.
