Collagen & Your Period: Hormone Cycle Guide for Vietnam
Collagen & Your Period: Hormone Cycle Guide for Vietnam
Okay, real talk: Anyone else notice their skin basically falls apart right before their period? Like clockwork, day 23-25 of my cycle, boom - three new pimples, dull complexion, and puffy face staring back at me in the mirror.
I used to think this was just "normal" period stuff until I started tracking my collagen intake alongside my menstrual cycle. Five months of obsessive note-taking later (yes, I'm that person), I discovered something fascinating: timing your collagen with your hormone cycle actually makes a huge difference.

As someone living in Ho Chi Minh City where humidity doesn't help matters, I've tested different approaches to figure out what really works for Vietnamese women dealing with monthly hormone chaos. Let me share what I learned - no fluff, just practical stuff that actually helped.
Why Your Skin Acts Wild During Your Period
Before diving into solutions, let's understand what's happening. Your hormones are basically on a rollercoaster every month:
Week 1 (Menstruation - Days 1-7):
- Estrogen and progesterone at lowest levels
- Skin tends to be drier, more sensitive
- Less natural oil production
- Collagen synthesis slows down
Week 2 (Follicular - Days 8-14):
- Estrogen rising (yay!)
- Skin looks amazing, glowy, hydrated
- Natural collagen production increases
- This is your "good skin week"
Week 3 (Ovulation - Days 15-21):
- Peak estrogen, then drops
- Progesterone starts rising
- Skin still pretty good but changes coming
- Oil production increases slightly
Week 4 (Luteal/PMS - Days 22-28):
- Progesterone peaks, estrogen low
- Inflammation increases
- Breakouts appear (especially jawline)
- Skin looks dull, puffy, irritated
- Collagen breakdown accelerates
The Vietnam factor: Our 85% humidity makes oil production worse during PMS week, and pollution in cities like Hanoi and Saigon triggers more inflammation.
How I Started Tracking Collagen with My Cycle
I'll be honest - I didn't plan this as some scientific experiment. I just got tired of wasting money on collagen that seemed to work sometimes but not others.
So I grabbed a notebook (old school, I know) and started logging:
- What day of my cycle
- How much collagen I took
- What my skin looked like
- Any breakouts or changes
- Energy levels
After three months, patterns emerged that shocked me.
The Cycle-Synced Collagen Strategy That Works
Based on my experience and chatting with other Vietnamese women (plus consulting my gynecologist friend), here's the approach that actually made a difference:
Week 1 - Menstruation (Days 1-7): Maintenance Mode
Dosage: 5g marine collagen daily Best time: Morning with breakfast Why: Your body is shedding and recovering. Gentle support is enough.
What I do:
- Take collagen with warm water and lime
- Focus on iron-rich foods (blood loss depletes iron)
- Drink extra water (3-4 liters in our heat)
- Skip intense workouts that might stress skin more
Skin focus: Hydration over everything. Vietnamese climate dries you out even more during period.
Week 2 - Follicular (Days 8-14): Glow Time
Dosage: 5-7g marine collagen daily Best time: Morning, maybe add evening dose Why: Estrogen is rising - your skin is primed to absorb and use collagen optimally.
What I do:
- Increase to 7g if skin needs extra boost
- Add vitamin C (from guava or supplement)
- This is when I try new skincare products
- Enjoy looking good because it won't last (sorry)
Skin focus: Build reserves for the tough weeks ahead.
Week 3 - Ovulation (Days 15-21): Peak Performance
Dosage: 7-10g marine collagen daily Best time: Split between morning and evening Why: Your body is still receptive, and you're building protection before PMS hits.
What I do:
- Max out collagen intake (10g total)
- Add collagen-rich Vietnamese foods: bone broth, fish soup
- Prep skin barrier for upcoming hormone drop
- Start reducing sugar intake (helps with PMS breakouts)
Skin focus: Prevention is easier than cure.
Week 4 - Luteal/PMS (Days 22-28): Damage Control
Dosage: 10g marine collagen daily MINIMUM Best time: Morning 5g, evening 5g Why: Progesterone is wrecking havoc. You need maximum support.
What I do:
- Double up on collagen
- Take with anti-inflammatory foods (turmeric, ginger tea)
- Reduce dairy (makes my breakouts worse)
- Sleep more (hard, I know, but crucial)
- Use AC at night (helps reduce inflammation)
Skin focus: Minimize damage and inflammation.
Real Results from My 5-Month Experiment
Before cycle-syncing collagen:
- 5-7 new pimples every PMS week
- Skin looked tired for 10 days each month
- Spent ₫2 million on spot treatments yearly
- Felt frustrated and hopeless
After cycle-syncing collagen:
- 1-2 small breakouts only (manageable!)
- Skin stays relatively calm even during PMS
- Saved money on emergency skincare
- Actually feel in control of my skin
Biggest surprise: My period cramps reduced too! Apparently collagen helps with inflammation overall, not just skin.
PMS Breakout Emergency Protocol
Even with perfect collagen timing, sometimes breakouts happen. Here's my rescue routine:
Morning of breakout:
- 10g collagen immediately
- Green tea (anti-inflammatory)
- Avoid touching face (hardest rule)
Throughout day:
- Reapply sunscreen (pollution + inflammation = disaster)
- Drink 1 liter water every 2 hours
- Avoid sugar completely
Evening:
- Another 5g collagen dose
- Gentle cleanser (not harsh acne washes)
- Spot treatment if needed
- Early sleep (before 11 PM)
Vietnam-specific tip: The humidity makes inflamed skin worse. I keep face mist in my bag and spritz every 2 hours when I'm outside.
Foods That Help (Vietnamese Options)
These Vietnamese dishes naturally support collagen during your cycle:
Follicular phase (Week 2): Focus on building
- Canh chua cá (sour fish soup) - omega-3 for collagen synthesis
- Rau muống xào tỏi (morning glory) - iron and vitamins
- Papaya salad - enzymes help collagen absorption
Luteal phase (Week 4): Focus on anti-inflammatory
- Chicken bone broth - natural collagen source
- Turmeric rice (cơm nghệ) - reduces inflammation
- Herbal teas - ginger, chrysanthemum
- Avoid: iced drinks, too much coffee, excess sugar
What About Birth Control?
Good question! I'm on birth control pills, which changes things slightly:
If you're on the pill:
- Your hormone fluctuations are less dramatic
- But you still have a "fake" cycle
- Stick to 5-7g collagen daily consistently
- May not need to cycle dosage as much
If you're not on contraception:
- Natural hormone swings are bigger
- Cycle-syncing collagen helps more
- Pay extra attention to Week 4
Check with your doctor if you're on hormonal IUD or other methods - everyone's different!
Budget-Friendly Approach
Look, taking 10g daily during PMS week adds up. Here's how to manage costs:
Smart strategy:
- Buy collagen in bulk (3-month supply) = better price
- Use full dose (10g) only during Week 3-4
- Reduce to 5g during Week 1-2
- Supplement with bone broth from wet market (cheap!)
Monthly cost breakdown:
- Week 1: 5g x 7 days = 35g
- Week 2: 7g x 7 days = 49g
- Week 3: 10g x 7 days = 70g
- Week 4: 10g x 7 days = 70g
- Total: ~224g per month
Versus flat 7g daily = 210g month. Slightly more, but way more effective.
Where to buy in Vietnam:
- Pharmacity (regular sales)
- Guardian (membership points)
- Online: Shopee/Lazada (check reviews carefully!)
Common Mistakes to Avoid
Taking same dose all month: Your hormones change, your collagen should too.
Stopping during period: That's when your body needs support most!
Ignoring diet: Collagen supplements alone won't fix terrible diet.
Not tracking: You won't see patterns without writing things down.
Expecting instant results: Give it 2-3 cycles to see real change.
When to See a Doctor
Cycle-syncing collagen helps, but some signs need professional attention:
- Severe cystic acne every month
- Irregular periods (over 35 days apart)
- Extreme PMS symptoms affecting daily life
- Skin getting worse despite consistent routine
- Suspecting PCOS or hormonal imbalance
Collagen is a supplement, not a cure for serious hormonal issues.
My Current Routine (Month 6)
Here's what I'm doing now that's working:
Daily basics:
- Track cycle on phone app (Flo or Clue)
- Adjust collagen based on cycle week
- Eat Vietnamese diet focused on whole foods
- Sleep 7-8 hours (struggle, but trying)
- Manage stress (meditation, walks)
Skincare:
- Gentle routine year-round
- Extra hydration Week 1
- Prevention focus Week 3-4
- Minimal products during PMS
Results: Best skin of my adult life. Not perfect, but consistent and manageable.
The Honest Truth
Cycle-syncing collagen isn't magic. You'll still get some breakouts. Your skin will still have off days. But after 5 months of doing this, I can tell you:
It makes a real difference. My monthly "bad skin week" is now more like "slightly annoying skin days."
It's empowering. Instead of feeling helpless against hormones, I have a strategy.
It saves money. Less emergency skincare shopping when you prevent problems.
It's sustainable. This is something I can do long-term without burning out.
If you're tired of your skin falling apart every month, give this approach a try for at least 3 cycles. Track what happens. Adjust based on your body's response.
And remember - we're in Vietnam, so humidity, pollution, and stress are extra factors. Be patient with yourself and your skin.
