My Son Is Studying for the DAT. His Skin Is Paying for It. Here's What I'm Sending Him

My Son Is Studying for the DAT. His Skin Is Paying for It. Here's What I'm Sending Him.

ClearSkin Daily

My son called me the other day. He's studying at UOP Dental School, deep in DAT prep — and he said: "Mom, breakouts during exam season are from cortisol, right? I learned about it in school." I told him he was exactly right. And then I put together a care package from Olive Young. This post is for him — and for everyone surviving exam season with stressed-out skin.


Why Stress Causes Breakouts — The Cortisol Connection

When you're stressed, your body releases cortisol — the stress hormone. And cortisol doesn't just affect your mood. It triggers a chain reaction that hits your skin hard.

How cortisol affects your skin

💧
Sebum overproduction
Cortisol stimulates the sebaceous glands → pores clog faster → more blackheads and breakouts
🛡️
Weakened immunity
Cortisol suppresses immune cells → skin becomes more vulnerable to inflammation and infection
🌙
Disrupted skin repair
Poor sleep from stress → skin can't recover overnight → breakouts get worse, not better

My son said both his breakouts and his frequent colds were connected — and he was right. Cortisol triggers both at the same time. A dental student who figured that out on his own — I was a proud mom. 😄

Stress Blackheads Are Different

My son mentioned his nose blackheads had gotten worse. Here's what's important to know: stress-related blackheads are not the same as regular blackheads.

Regular blackheads form when sebum and dead skin cells gradually build up in a pore. Stress blackheads happen because cortisol causes a sudden surge in sebum production — pores clog much faster than usual. That means you need to be more proactive about pore care during stressful periods.

⚠️ Do not squeeze. When your immunity is already low, squeezing blackheads or pimples dramatically increases the risk of inflammation and scarring. Especially during exam season when your body is already run-down — hands off.

What I'm Sending My Son — The Exam Season Kit

He asked me to pick products for him. The rule for a busy student: simple and fast. A 10-step routine doesn't work during exam season. Here's what actually does.

🧴

BHA (Salicylic Acid) — Blackhead Essential

Salicylic acid dissolves the sebum inside the pore — the most effective OTC ingredient for blackhead prevention. Use 2–3 times a week around the nose area. Always wear SPF on days you use it. Apply after cleansing, let it absorb, then moisturize.

💧

Hyaluronic Acid Serum — Sleep-Deprived Skin Essential

Sleep deprivation causes a rapid drop in skin hydration. Dry skin overcompensates by producing more oil — making blackheads and breakouts worse. Hyaluronic acid locks in moisture and breaks this cycle. Apply after cleansing every evening — takes 10 seconds and makes a visible difference by morning.

🩹

Hydrocolloid Patches — Emergency Use

Stress makes people unconsciously touch their face more. The moment a pimple appears, put a patch on immediately. When immunity is low, even minor contact can spread inflammation significantly. Mighty Patch Original — patch it the moment it appears, not after. Studying with a patch on also physically stops the unconscious habit of touching your face while you concentrate.

🌿

Non-Comedogenic Moisturizer — Don't Skip This

Even oily skin needs moisture during stress. The key is non-comedogenic — won't clog pores. Without this, dehydrated skin produces even more sebum. 5 seconds after hyaluronic acid — and your evening routine is done.

The Exam Season Routine — 3 Steps Only

No one studying for a major exam has time for a complex skincare routine. Here's what actually works when you're busy:

🌙 Evening — 3 steps only

Step 1 — Gentle cleanser with lukewarm water
Step 2 — BHA around nose area (2–3x per week only)
Step 3 — Hyaluronic acid serum + non-comedogenic moisturizer

☀️ Morning — 2 steps only

Step 1 — Light moisturizer
Step 2 — SPF (non-negotiable on BHA days) — ROUND LAB Birch Juice Sun Stick SPF 50+ is perfect for students: no mess, reapplies over everything, fits in any bag

If a pimple appears → patch it immediately. That's it. This is enough to get through exam season without making things worse.

The Bottom Line

Exam season breakouts are a cortisol problem. You can't eliminate stress — but you can manage your skin through it. BHA for pores + hydration + patches for emergencies + SPF in the morning. That's enough.

To my son: good luck on your DAT. 💜 And to everyone else surviving exam season — you've got this.

Going through exam season right now? Leave a comment — I'd love to hear what's working for you. 🔬

The Doctor Said No Pizza, No Burgers, No Ramen — I Said Something Differen

Does Food Cause Acne? What I Tell My Teenage Clients (It's Not a Forbidden List) ClearSkin Daily A high school client came in after a checkup and showed me the list his doctor had given him. No meat. No dairy. No eggs. No pizza. No burgers. No chicken. No ice cream. No ramen. He looked at me and said: "If I hadn't come to you first and just gone straight to the doctor — I would have starved to death." I laughed. And then I gave him a completely different answer than his doctor did. Does Food Affect Acne? The Honest Answer Parents and students ask me this constantly. And I always say the same thing: yes, food affects acne. Of course it does. Anyone who tells you otherwise isn't being honest. But here's the part that gets left out of that conversation: Stress also causes acne. And for a teenager in exam season — being told they can't eat meat, dairy, eggs, pizza, burgers, chicken, ice cream, or ramen is a significant source of stress. ...

My Daughter the Nurse Showed Me Her Skincare Routine. Here's My Verdict. ClearSkin Daily Today I have a special guest — my daughter. She's 25, works as a nurse at Stanford Hospital, and has been dealing with closed comedones (those tiny bumps under the skin) for a while. She sent me a list of Olive Young products she'd been trying, and asked me to check the ingredients. So that's exactly what we're doing today. 😊 First — What Are Closed Comedones? Before we get into the products, let's make sure we're talking about the same thing. Closed comedones are also called whiteheads — they form when a pore gets blocked and sebum gets trapped beneath the skin. There's no inflammation, but the skin texture becomes uneven, and if you pick at them, they can turn into full inflammatory acne. The key to treating closed comedones It's all about exfoliation — specifically, dissolving the dead skin cells that are blocking the pore so sebum ca...
