C-Bomb – Vitamin C Brightening Serum
Description
VITAMIN C BRIGHTENING SERUM
Not all vitamin C is created equal — and C-Bomb is proof. This high-performance vitamin C brightening serum is designed to give you real glow results without the burn, crust, or irritation. It features a triple-threat complex: pure L-Ascorbic Acid, 3-Glyceryl Ascorbate, and Magnesium Ascorbyl Phosphate, all stabilized to brighten skin without oxidation.
Unlike harsh serums that sting or pill under makeup, C-Bomb is a vitamin C brightening serum made for sensitive skin and real life. Lightweight, breathable, and non-sticky, it absorbs fast and layers beautifully under primer or Glow Glue. With calming extracts like calendula, chamomile, and rice, it soothes while it works—making it the ultimate brightener for tired, post-acne, or dull skin.
This formula visibly fades dark spots, evens tone, and restores radiance without triggering breakouts or greasiness. Whether you’re oily, normal, or combo, this vitamin C brightening serum delivers.

- Non-Irritating – Designed for sensitive skin with soothing extracts
- Makeup-Safe – No pilling or crusting under glam

protect your pretty
Before the blush, before the liner, before you even reach for your glam, it’s your skin that shows up first. And it deserves protection. We don’t believe in choosing between skincare or makeup. We built products that let you do both, without the breakouts, the irritation or the regrets.
Frequently asked questions
We don’t just formulate skincare, we formulate under-makeup skincare. That means every product is designed to sit comfortably under your makeup without causing breakouts, irritation, or pilling. Our formulas support your skin’s barrier, reduce redness, and prevent those frustrating “skin moments” that show up when you need your glow the most.
Absolutely. Glow Glue® is our pre-makeup star, which acts like a breathable shield for your skin. It's made to sit right under your glam without pilling, slipping, or irritation. It grips makeup like a primer while feeding your skin barrier the nourishment it craves.
The rest of our lineup? While they’re not meant to be layered right before a full face, they’re packed with barrier-supporting ingredients that protect and repair skin that wears makeup often. We recommend using them sparingly on makeup days. Think of them as your skin’s recovery team, not part of your pre-glam stack.
Yes! While our products are formulated to protect and prep skin under makeup, they’re just as effective on bare skin. Think of them as your daily skin shield... makeup or not.
It’s skincare that understands makeup. Every formula is lightweight, fast-absorbing and makeup-friendly, so you can build your routine underneath your favorite foundation without compromising your skin.
Always. MyDay Skincare is proudly cruelty-free. Most of our lineup is vegan too (check individual product pages for details).
