You've been doing skincare for months, maybe even years. You've spent hundreds on products. You've watched every tutorial. But your skin still looks tired, dull, and older than it should. Sound familiar? You're not alone. Most people are making the same skincare mistakes that are actually making them look older instead of younger.
I've seen it happen to friends, family, and even myself. We think we're doing everything right, but we're actually sabotaging our skin without even knowing it. The good news? Once you know what you're doing wrong, fixing it is easier than you think.

The 7 Deadly Skincare Sins (And How to Fix Them)
Mistake #1: You're Using Hot Water to Wash Your Face
Why It's Aging You: Hot water strips your skin of its natural oils, leaving it dry, irritated, and vulnerable to environmental damage. It also causes inflammation, which accelerates the aging process.
The Science: Your skin has a natural barrier made of oils and lipids. Hot water dissolves these protective oils, leaving your skin exposed to pollution, bacteria, and free radicals that cause premature aging.
The Fix: Use lukewarm water (room temperature or slightly warm) to wash your face. Your skin should feel comfortable, not scalded.
Product Recommendation: COSRX Low pH Good Morning Gel Cleanser is perfect for gentle cleansing without stripping your skin. Its low pH formula respects your skin's natural barrier.

Mistake #2: You're Skipping Sunscreen Indoors
Why It's Aging You: UV rays penetrate windows, and blue light from screens causes oxidative stress that breaks down collagen and elastin. Even on cloudy days, you're getting UV damage.
The Science: UVA rays (the aging rays) can penetrate glass and cause cumulative damage that shows up as wrinkles, dark spots, and loss of firmness years later.
The Fix: Wear sunscreen every single day, even if you're staying inside. Look for broad-spectrum protection with at least SPF 30.
Product Recommendation: Beauty of Joseon Relief Sun is lightweight, doesn't leave a white cast, and provides excellent protection. It feels like a moisturizer, so you'll actually want to wear it.

Mistake #3: You're Over-Exfoliating
Why It's Aging You: Too much exfoliation damages your skin barrier, causing inflammation, redness, and making your skin more vulnerable to environmental damage. It can also cause micro-tears that lead to premature aging.
The Science: Your skin needs time to repair itself. Over-exfoliation disrupts the natural cell turnover process and can cause long-term damage to your skin's protective barrier.
The Fix: Limit exfoliation to 2-3 times per week maximum. Use gentle chemical exfoliants instead of harsh physical scrubs.
Product Recommendation: The Ordinary Salicylic Acid 2% Solution is a gentle chemical exfoliant that won't damage your skin barrier when used correctly.

Mistake #4: You're Not Moisturizing Enough
Why It's Aging You: Dehydrated skin looks dull, shows more fine lines, and ages faster. When your skin lacks moisture, it can't repair itself properly, leading to accelerated aging.
The Science: Moisture is essential for skin cell function. Without proper hydration, your skin can't maintain its elasticity or repair damage from environmental stressors.
The Fix: Use a moisturizer twice daily, and consider adding a hydrating serum to your routine. Look for ingredients like hyaluronic acid, glycerin, and ceramides.
Product Recommendations:
- Hada Labo Gokujyun Premium Lotion for intense hydration
- CeraVe Moisturizing Cream for barrier repair

Mistake #5: You're Using Products in the Wrong Order
Why It's Aging You: Applying products in the wrong order means they can't penetrate properly, so you're not getting the full benefits. This wastes money and prevents you from seeing results.
The Science: Product penetration depends on molecular size and consistency. Thinner products need to go first, while thicker products create a barrier that prevents absorption.
The Fix: Apply products from thinnest to thickest consistency: cleanser → toner → serum → moisturizer → sunscreen (morning) or oil (night).
The Correct Order:
- Cleanser
- Toner
- Essence
- Serum
- Moisturizer
- Sunscreen (morning) or Face Oil (night)

Mistake #6: You're Touching Your Face Constantly
Why It's Aging You: Every time you touch your face, you're transferring bacteria, oil, and dirt from your hands. This can cause breakouts, irritation, and inflammation that accelerates aging.
The Science: Your hands come into contact with thousands of bacteria throughout the day. Rubbing your eyes, resting your chin on your hand, or picking at your skin all transfer these to your face.
The Fix: Be conscious of face-touching habits. Keep your hands away from your face, and if you need to touch it, wash your hands first.
Pro Tip: If you're a chronic face-toucher, try wearing a ring or bracelet as a reminder to keep your hands busy.

Mistake #7: You're Not Getting Enough Sleep
Why It's Aging You: During sleep, your skin repairs itself and produces collagen. Without adequate sleep, your skin can't recover from daily damage, leading to accelerated aging.
The Science: Sleep deprivation increases cortisol levels, which breaks down collagen and elastin. It also reduces blood flow to your skin, making it look dull and tired.
The Fix: Aim for 7-9 hours of quality sleep per night. Create a relaxing bedtime routine and avoid screens before bed.
Product Recommendation: COSRX Advanced Snail 96 Mucin Power Essence helps repair skin damage overnight, making it perfect for your evening routine.
