By Terry Brightening CC Serum is a makeup-skincare hybrid that delivers sheer radiance, subtle color-correction, and a soft-focus finish you can wear alone, under foundation, or mixed right in. If you’ve seen “Cellularose CC Serum” in older videos or posts, that’s the same icon under its former name; the formula concept remains a glow-first primer-serum with light-diffusing pigments and a skincare-heavy base. On the brand’s product page you’ll see the positioning spelled out—an illuminating primer with a 96% skincare-based formula, “Optical Glow” technology, eight shades, and usage options from all-over priming to mixing into base makeup.

What Is a Brightening CC Serum (By Terry focus)
A brightening CC serum is best thought of as complexion make-up with skincare sensibilities. In By Terry’s case, it’s a translucent, glow-boosting base that colour-corrects and evens out the look of tone without traditional coverage. The official page describes a lightweight serum texture, a skincare-first formula, and an application menu: prime all over, tap on high points, or mix a few drops into foundation. BY TERRY EU
If you came across the older Cellularose name, retailer listings still reference it (and they also outline how to use it—alone, under, or mixed, plus shade tricks like using deeper tones to sculpt). That legacy naming is why many people search both “By Terry Brightening CC Serum” and “By Terry Cellularose CC Serum.” Dermstore
How It Works: optical glow, pigments, and the skincare base
The appeal is in the optics. By Terry explains that Optical Glow technology blends light-reflecting prisms, soft-focus microspheres, and colour-correcting pigments to blur texture and gently neutralize unevenness while letting real skin show through. Ingredient lists reveal familiar radiance helpers—mica and titanium dioxide among them—along with a skin-comforting base that includes humectants and silicones for slip. You’ll also see the brand’s signature rose stem cell story in the description. BY TERRY EU
Where does this fit alongside “true skincare” brighteners? CC serum is makeup-forward; it visually evens tone immediately. If you want biologic pigment support over time, you’d add proven actives (think vitamin C or niacinamide) underneath or in your night routine—more on that below, with evidence for vitamin C’s depigmenting role from a 2023 systematic review.

Shades & Finishes: finding your match
By Terry lists eight shades, each tuned to an undertone and depth—ranging from fair brighteners (Immaculate Light, Rose Elixir) to warm complexion-revivers (Apricot Glow), sun-kissed tones (Sunny Flash), and deeper flattering bronzes (Sienna Light). The brand also provides quick guidance for what each shade does (e.g., Sunny Flash to add warmth on medium-deep skin or a bronzy wash on fair complexions). Use them strategically: all over for a veil, or targeted on high points for a subtle strobe. BY TERRY EU
If you prefer coverage, the companion Brightening CC Foundation page even suggests priming with the CC Serum, then layering the foundation—useful if you want a brighter base with more evenness through the T-zone. BY TERRY
Who It’s For (and smart expectations)
- You love skin to look like skin. CC serum keeps it sheer; think “good-light day,” not full-coverage correction.
- You’re after redness softening or dullness lift without a heavy finish; the optical pigments do the immediate heavy lifting. BY TERRY EU
- You want flexibility. Wear it solo on casual days, layer under foundation for glow, or mix it in to customize.
Have deeper skin or are melasma-prone? CC serum is cosmetic, not treatment. For long-term pigment management, dermatology sources consistently emphasize daily sunscreen; tinted sunscreens with iron oxides help defend against visible light, which can worsen dark spots. Use them under or over your CC routine. AAD+1
Dry or dull? Slip a hydrating layer underneath—something like a hydrating serum to revive dull tone such as d’Alba White Truffle Prime Intensive Serum makes the CC veil sit more evenly.
How to Use & Routine Pairings
Three easy modes show up across the brand and retailer how-tos:
-
All-over primer: Smooth a thin layer over skincare for a bright, soft-focus base. BY TERRY EU
-
Mix-in: Blend a drop with foundation or skin tints to add radiance without extra layers. BY TERRY EU
-
Targeted glow: Tap onto cheekbones or brow bones as a finishing sheen. Retailers also note using deeper shades as soft sculpt. Dermstore
AM flow for staying power:
- Gentle gel cleanse before actives to avoid over-stripping; a simple option is Hera Refreshing Cleansing Foam.
- Hydrating serum if needed.
- Tinted sunscreen with iron oxides if you’re spot-prone from visible light (layer first, let set). AAD+1
- CC serum: all over, mixed, or strategic.
- Concealer/foundation where desired.
PM support (optional):
On low-irritation nights, very gently resurface with Medicube Zero Pore Pads 2.0 to smooth texture so light reflects more evenly the next day. Follow with moisturizer.
Brightening serum pairings:
- For an AM antioxidant step under makeup, a daily brightening boost with glutathione actives like AHC Pro Shot Gluta Activation Bright 3 Intra serum can layer well.
- If you prefer spot-targeting before makeup, reach for a concentrated ampoule for stubborn spots such as MIGUHARA Ultra Whitening Perfect Ampoule—use sparingly where marks linger.
Types, Companions & How to Choose
CC serum vs CC foundation: If you want the glass-skin sheen without coverage, the serum is your lane; if you need more unifying, the By Terry Brightening CC Foundation builds coverage while keeping luminosity (and the brand suggests priming with the serum first). BY TERRY
Powder/Palette synergy: By Terry also offers Brightening CC Palette/CC Powder to finish and amplify radiance—think colour-correcting powder with rose-infused claims. If you enjoy a polished finish (or get shiny), a light dusting can lock the glow without dulling it. BY TERRY
When to keep it skincare-first: If hyperpigmentation is your main concern, keep makeup flexible and invest in evidence-backed actives. For example, vitamin C shows depigmenting benefits in a 2023 systematic review—steady use is the trick, not maximal strength. If serums feel too active, a vitamin C cream to buffer active routines like Dr.Vita Vitamin C Cream can be friendlier. Wiley Online Library
Comparisons & Alternatives
CC serum vs vitamin C/niacinamide serums: CC serum offers instant optical brightening; skincare actives work slowly on pigment pathways. Many people do both: actives in AM/PM, CC serum for daytime radiance. (If you’re very reactive, start with hydration only, then re-introduce brights.)
CC serum vs foundation: Foundation evens tone via coverage; CC serum keeps skin more visible with a glow filter. You can layer: prime with CC serum, then apply your usual base on areas that need more uniformity. BY TERRY
For deeper tones & melasma-prone skin: Protection is step one. Dermatology guidance highlights tinted sunscreens with iron oxides for visible-light defense—especially helpful for stubborn pigment disorders. Keep this under your CC routine. JAAD+1
FAQs
Is the Cellularose CC Serum the same as Brightening CC Serum?
It’s the same franchise—older listings still say “Cellularose,” but the current positioning and usage are the glow-first primer-serum you see today. Dermstore
How do I pick a shade—Apricot Glow or Sunny Flash?
Apricot Glow gently warms and revives dullness; Sunny Flash runs more bronzy and can unify medium-deep tones or add sun-kiss to lighter skin. Try all-over for warmth, or use deeper shades to softly sculpt. BY TERRY EU
Should I wear sunscreen with it?
Yes—makeup isn’t sunscreen. If you’re spot-prone, tinted sunscreen with iron oxides is preferred for visible light as well as UV. Apply first, let it set, then layer CC serum. AAD
Can I mix CC serum into any foundation?
Generally yes—By Terry even suggests the mix-in approach. Start with one drop and adjust to taste. BY TERRY EU
Any pro tips for day-to-day?
Use a light exfoliation night (skip if sensitive) so texture looks smoother under optics; smooth a hydrating layer under CC for dryer days; and keep spot care targeted so the glow remains skin-like. (See the Medicube and d’Alba options linked above.)
Bottom Line
By Terry Brightening CC Serum is the easy button for radiance: a sheer, colour-correcting veil with soft-focus optics that can be worn alone, under, or mixed with foundation. For everyday makeup that reads as skin, it’s hard to beat. If tone-evening over time is your priority, combine it with daily sun protection—ideally tinted SPF with iron oxides—and steady, evidence-based brighteners in your skincare routine (vitamin C, etc.). Then let the CC serum do what it does best: catch the light and keep things effortless. AAD+2JAAD+2
