Blue Pea Flower (Clitoria ternatea), known locally as Nil Katorolu, is prized for its striking colour and gentle, caffeine‑free character. Beyond its visual charm, it’s often chosen for beauty‑from‑within routines: a daily cup can sit alongside sunscreen, steady hydration, colourful meals and consistent sleep. Plant‑based phytochemicals are increasingly studied for skin benefits—from helping preserve elasticity to supporting healthy repair—by buffering everyday oxidative stress and influencing enzymes that break down key skin proteins . Meanwhile, collagen itself remains central to wound repair and skin structure; modern wound and skincare practice continues to rely on collagen’s film‑forming, moisture‑protective and scaffold‑support roles .
Although evidence specific to Blue Pea Flower and skin is still emerging, early work with topical butterfly pea extract is encouraging, and aligns with broader dermatological science on antioxidants, collagen and barrier care. Use it as a soothing ritual within a well‑rounded routine rather than a stand‑alone fix.
Why Collagen and Oxidative Balance Matter for Skin
- Collagen is the most abundant structural protein in the body and a cornerstone of skin integrity and wound repair .
- In topical care, collagen’s film‑forming properties help reduce transepidermal water loss (TEWL) and shield skin from surfactant damage; these effects are often enhanced by pairing collagen with other polymers in formulations.
- In wound management, selecting support that matches the healing phase—scaffold, moisture balance, matrix metalloproteinase (MMP) modulation or antimicrobial aid—improves outcomes, underlining collagen’s varied roles in practice.
- Many anti‑ageing strategies focus on limiting oxidative stress and the enzymes that degrade the extracellular matrix. Plant‑derived actives that temper collagenase, elastase and hyaluronidase activity help protect collagen and elasticity .
- Broadly, plant phytochemicals have been reported to improve skin elasticity, reduce hyperpigmentation, prevent breakdown of key skin proteins and support wound healing, reinforcing a diet‑and‑topical approach to skin longevity .
What the Research Suggests about Butterfly Pea (Nil Katorolu)
- A study of a butterfly pea flower extract cream in a post‑microneedling (dermapen) wound‑healing context reported support for collagen synthesis during the remodelling phase, highlighting a plausible topical pathway for aiding normal repair .
- As we age, skin collagen naturally declines. This has inspired innovations that pair butterfly pea extract with collagen in beverage formats targeting premature ageing—an indicator of growing interest in combining botanical antioxidants with collagen support .
- While popular media often touts “blue tea” as a collagen booster, the strongest evidence base sits with general principles: plant‑based phytochemicals can moderate oxidative stress and protease activity, both of which influence how skin looks and recovers day to day.
Taken together, Nil Katorolu can play a supportive role within a lifestyle that protects collagen and keeps oxidative stress in check.
How Blue Pea Flower May Support Skin Appearance and Repair
- Antioxidant context: By contributing plant polyphenols to the diet, Blue Pea Flower may help buffer everyday oxidative stress—one of the signals that upregulates collagen‑degrading enzymes .
- Collagen‑friendly habits: Nutrition quality, sun protection and sleep all influence collagen metabolism; adding a polyphenol‑rich, caffeine‑free tea may complement these pillars.
- Wound‑care insights: Collagen’s scaffold and moisture‑balancing roles make it fundamental to normal healing. While tea is not a wound dressing, broader research on collagen and botanical actives offers useful context for topical routines and professional care plans.
A Beauty‑Friendly Daily Ritual
- Brew: Steep 1–2 teaspoons of dried flowers in hot water for 5–7 minutes; strain. For a smoother profile and deeper colour, cold‑brew for 6–12 hours.
- Pairings: Lemon or lime (enjoy the blue‑to‑purple shift), ginger, lemongrass, mint or a drizzle of honey.
- Rhythm: Many people enjoy 1–2 cups daily with meals or as an evening wind‑down.
- Plate it smart: Combine with a colourful, plant‑forward diet to widen your phytochemical spectrum—an approach consistently associated with skin‑ageing benefits.
- Topical note: If experimenting with DIY rinses or compresses, patch test first and be aware the infusion can stain fabric (and occasionally skin) temporarily.

Where Blue Pea Fits with Professional Skincare
- Keep your SPF daily. Antioxidant habits complement sun‑smart protection; they don’t replace it.
- Moisturise intelligently. Products that reduce TEWL and reinforce the barrier echo collagen’s film‑forming benefits in topical science.
- Be patient with repair. Wound healing progresses through phases; aligning actives and routines to the right stage is a principle taken from advanced wound‑care practice.
- See a clinician for persistent concerns. Botanicals are supportive. Medical advice is essential for conditions such as eczema, acne or delayed healing.

FAQs
- Can it replace skincare?
No. Think of Blue Pea Flower as inside–out support alongside a gentle routine and daily SPF. Plant‑based actives are valuable partners to, not substitutes for, well‑chosen topicals. - Is there evidence for wound support?
In a post‑dermapen setting, a butterfly pea extract cream was reported to support collagen synthesis during remodelling, which is consistent with broader collagen‑and‑wound science. - Will it boost collagen on its own?
Collagen declines with age, and research explores pairings of butterfly pea extract with collagen in nutrition formats; however, lasting results come from the whole routine—nutrition, protection and sleep—supported by phytochemicals that help limit protein breakdown . - Can I use it topically?
Some people experiment with cool infusions, but staining is possible. Patch test, keep expectations modest, and prioritise evidence‑based skincare.
