5 Reasons BLOOM is The Champion for Pre + Post Sun Care
BLOOM was built differently. Waterless, concentrated, and loaded with actives that work at a cellular level — here are the five science-backed reasons BLOOM outperforms everything else for pre and post sun care.
1. REDUCES DAMAGE — BEFORE AND AFTER IT HAPPENS
UV radiation doesn't just burn the surface — it triggers oxidative stress deep in the epidermis, generating free radicals that damage skin cells, lipids, and DNA. The window for intervention is narrow: the first 24 hours after exposure are the most critical.
BLOOM's stabilized Vitamin C (Tetrahexyldecyl Ascorbate) is a lipid-soluble antioxidant that stays active and delivers where basic water-based formulas can't reach. Applied before sun exposure, it primes your skin's antioxidant defenses. Applied after, it neutralizes the free radical cascade before it compounds into deeper damage.
Kawashima et al. (2018) demonstrated that both pre- and post-treatment with Vitamin C meaningfully reduced UVB-induced damage in human epidermis — confirming that timing matters, and that the right form of Vitamin C delivered at the right concentration can intervene in the damage cycle at a cellular level.
The true importance here: it needs to deliver in its pure format.
Most after-sun products are 95%+ water. That means the Vitamin C you're paying for is diluted or is oxidized. if you have ever picked up product and noticed it's "color sift" to tan or brown, it longer holds the power to help the skin. BLOOM's format and high level of stabilized version, delivers actives at full potency where it needs to be
2. REDUCES STING + ERASES RED
That burning, stinging sensation after sun overexposure? That's your skin's inflammatory response in full activation — blood flow surging, immune signals firing, and prostaglandins driving visible redness and heat. Most products cool the surface. BLOOM works on the signaling cascade underneath.
Licorice Root (Stearyl Glycyrrhetinate) is one of BLOOM's most clinically recognized actives and is even considered a quasi drug in Japan at our level of use. Afnan et al. (2016) showed that glycyrrhizic acid — the bioactive compound in licorice — protects against UVB-induced skin damage by modulating key inflammatory signaling pathways, reducing both the intensity and duration of the inflammatory response.
Paired with our extra calming floral extracts — Blue Chamomile, Blue Tansy, Monoi de Tahiti, and Hibiscus — BLOOM delivers chamazulene and flavonoid-rich botanicals that rapidly soothe the sting and visibly reduce redness. Not by masking it. By addressing the biology driving it.
The result: skin that calms faster, looks less angry fast, and recovers without the prolonged discomfort as it repairs.
3. SUPPORTS BARRIER REPAIR
UV exposure doesn't just damage skin cells — it disrupts the lipid barrier that holds everything together. When the stratum corneum is compromised, trans-epidermal water loss (TEWL) spikes, moisture escapes, and the skin becomes vulnerable to further irritation, infection, and prolonged inflammation.
Egawa & Kabashima (2018) documented how UV-induced barrier dysfunction creates a cascade of downstream damage — and that restoring the lipid barrier is a prerequisite for meaningful skin recovery, not an afterthought.
BLOOM's skin-mimicking lipid complex — Organic Jojoba, Olive, and Squalane — is biocompatible with the skin's own lipid matrix. These aren't just moisturizers. They're barrier-rebuilding actives that replenish the exact lipid structures UV exposure degrades. Squalane reinforces microbiome balance. Jojoba mimics sebum. Olive delivers essential fatty acids that seal the barrier and reduce TEWL.
Waterless actives helping the skin rebuild proteins, natural moisturizing factors, and key lipids is the key differentiator. Our formulas are inherently more compatible with the stratum corneum than water-dispersed products, allowing actives to absorb more efficiently and work where barrier repair actually happens. All without the extra hidden stabilizers or sensitizers.
4. CALMS UV-INDUCED INFLAMMATION
Sunburn isn't a surface event — it's a systemic inflammatory response. UVB radiation activates NF-κB signaling, triggers cytokine release, and initiates a cascade that, left unchecked, accelerates photoaging, hyperpigmentation, and collagen degradation. Cooling the skin feels good. Interrupting the inflammatory cascade is what actually changes outcomes.
Kong et al. (2015) demonstrated that 18β-glycyrrhetinic acid — the active metabolite of licorice root — provides measurable protection against UV-induced photoaging by suppressing inflammatory mediators and reducing oxidative stress at a cellular level.
BLOOM's licorice root complex works synergistically with Magnolia Bark — a natural source of honokiol and magnolol, compounds with documented anti-inflammatory and antioxidant activity — to interrupt the UV-triggered inflammatory cascade from multiple angles. This isn't single-ingredient skincare. It's a coordinated anti-inflammatory system designed to work with your skin's repair biology.
The difference shows: less prolonged redness, reduced risk of post-inflammatory hyperpigmentation, and skin that returns to baseline faster.
5. SUPPORTS REPAIR AT THE CELLULAR LEVEL
Recovery from UV damage isn't passive and is in limited timing (first 48 hrs)— it's an active biological process that requires the right building blocks. Keratinocyte viability, collagen biosynthesis, basement membrane integrity, and barrier reconstruction all depend on specific nutrients being present at the right concentrations.
Boyce et al. (2002) established that Vitamin C directly regulates keratinocyte viability, epidermal barrier function, and basement membrane formation — the foundational structures that UV exposure degrades. Pullar et al. (2017) further confirmed Vitamin C's essential roles in collagen synthesis, antioxidant protection, and overall skin health — with evidence that topical delivery can meaningfully support these processes.
BLOOM's stabilized vitamin C (Tetrahexyldecyl Ascorbate) is delivering ascorbic acid with little concern of oxidation and at clinical backed levels. Without the cellular support damages cannot be excised from DNA which leads to planned cell death aka apoptosis. We see it as peeling of the skin that could not repair itself.
This is why BLOOM works as a daily pre-sun primer, not just an emergency rescue. Applied before SPF every morning, it delivers the antioxidant and structural support your skin needs to handle cumulative UV exposure — preventing the slow accumulation of damage that shows up years later as hyperpigmentation and premature aging.
ACTIVE LEVELS SO POTENT, JAPAN CLASSIFIES THEM AS QUASI-DRUGS
Japan's pharmaceutical regulatory framework recognizes a category called quasi-drugs (準医薬品, jun-iyakuhin)—products that contain active ingredients at concentrations high enough to have a measurable physiological effect on the body, but that fall just below the threshold of a prescription drug. Sunscreen actives like UV filters and certain antioxidant compounds used in after-sun recovery have been evaluated under this framework precisely because of their documented biological activity on skin cells.
This isn't a marketing claim—it's a regulatory acknowledgment that the right actives, at the right concentrations, genuinely do something. BLOOM's formula is built around this philosophy: not cosmetic-grade dilutions, but efficacious levels of stabilized antioxidants and phytoactives that work with your skin's repair biology. Research confirms that UV-induced skin damage operates at a cellular level—and that targeted actives can meaningfully intervene in that process.
THE FORMULA BEHIND THE FIVE
Every claim above is backed by an ingredient in BLOOM's formula. No filler. No water diluting your actives. No synthetic preservatives masking instability. Just a waterless, concentrated system built around what UV-stressed skin actually needs:
- Stabilized Vitamin C (Tetrahexyldecyl Ascorbate) — lipid-soluble, light-stable, non-irritating. Penetrates deeply, neutralizes free radicals, supports collagen recovery, fades post-sun discoloration. Recognized as quasi drug in Japan and functional cosmetic in Korea.
- Licorice Root (Stearyl Glycyrrhetinate) — clinically recognized anti-inflammatory. Reduces redness, inhibits melanin overproduction, interrupts the UV-triggered inflammatory cascade. Recognized as quasi drug in Japan and functional cosmetic in Korea.
- Skin-Mimicking Lipids (Jojoba, Olive, Squalane) — barrier-rebuilding actives that replenish the lipid matrix UV exposure degrades. Reduces TEWL, seals in recovery, supports microbiome balance.
- Calming Floral Complex (Monoi de Tahiti, Blue Chamomile, Blue Tansy, Hibiscus, Magnolia Bark) — chamazulene, flavonoids, and antioxidant-rich botanicals that rapidly soothe sting, reduce redness, and support gentle cell turnover.
- Amino Acids + Natural Moisturizing Factors — building blocks to proteins, replenish hydration, structure, and barrier components. Work in harmony with Vitamin C to support the full repair cycle.

HOW TO USE
Pre-sun: Apply BLOOM to clean, dry skin after LUCID and before SPF. It primes the barrier, smooths the skin for better sunscreen adhesion, and delivers daily antioxidant protection against cumulative UV oxidative stress.
Post-sun: Apply as soon as skin feels discomfort — ideally within the first few hours of overexposure. Glide directly over affected areas; it liquifies on contact, forming a breathable, lightweight layer. Apply liberally. Reapply as needed. A second or third application before bed on the day of exposure can significantly expedite results. Avoid direct sunlight until skin normalizes.
Daily: Pairs seamlessly with NOVA or OASIS. Apply before OASIS or NOVA for amplified anti-redness and brightening benefits.
