Tretinoin is one of the most powerful, effective skincare ingredients available today. It's often described as the “gold standard” for treating acne, pigmentation, and signs of ageing.

But here’s the truth: Tretinoin is not for everyone. And using it without medical guidance can do more harm than good.

Before you apply a single drop, read this.

What Is Tretinoin and Why the Hype?

Tretinoin is a prescription-strength form of vitamin A (a retinoid), commonly used to:

• Treat acne and clogged pores

• Improve skin texture and tone

• Reduce fine lines and hyperpigmentation

• Boost collagen production

It works by speeding up skin cell turnover, which is why results can be dramatic. But with that power comes responsibility — and risk.

You Should NOT Use Tretinoin If...

Tretinoin is a medication. That means it’s not appropriate for everyone, and there are clear contraindications. You should not use it if:

🚫 You’re pregnant or breastfeeding

Tretinoin is not recommended during pregnancy or nursing due to potential risks.

🚫 You have active eczema, rosacea, or inflamed skin

Tretinoin can worsen irritation and sensitivity in people with certain skin conditions.

🚫 You've had recent cosmetic procedures

This includes chemical peels, microneedling, laser treatments, or waxing. Your skin needs time to recover before starting Tretinoin.

🚫 You’re already using strong actives

Using Tretinoin with AHAs, BHAs, benzoyl peroxide, or high-strength vitamin C can overwhelm your skin if not managed properly.

🚫 You’re not ready for sunscreen (every day, no excuses)

Tretinoin makes your skin more sensitive to the sun. Daily broad-spectrum SPF is mandatory.

Why You Should NEVER Start Tretinoin Without a Consultation

Tretinoin is prescription-only for a reason. Using the wrong strength, applying it too frequently, or ignoring contraindications can lead to:

• Redness, peeling, burning

• Long-term skin barrier damage

• Worsened breakouts or pigmentation

• Delayed results due to incorrect usage

That’s why we require all customers to complete a medical consultation before purchasing Tretinoin from Skin By Science.

How to Use Tretinoin Safely and Successfully

If you are approved to use Tretinoin, here’s how we guide you to start:

• Begin with a low frequency (e.g. 2x/week)

• Use a gentle cleanser and a non-active moisturiser

• Apply only a pea-sized amount to dry skin

• Avoid combining with other exfoliating actives unless directed

• ALWAYS use SPF 30+ every morning

Your skin might purge or flake early on — this is normal, but manageable with the right guidance.

Conclusion: Treat Tretinoin Like Medicine

Tretinoin can completely transform your skin — but only if it’s used correctly, consistently, and with proper medical oversight.
