Hey Glow Getters ✨
Welcome to another edition of GlowNotes, By Cosmetology—your go-to space for expert skincare education and honest beauty advice. Today, we’re diving deep into one of skincare’s most powerful ingredients: retinol.
Whether you’re dealing with fine lines, breakouts, pigmentation, or dull skin, retinol has likely come up in your search for answers. But between all the conflicting advice and product options, figuring out what’s right for your skin can be overwhelming.
In this guide, I’ll break down exactly what retinol is, how it works, how to use it safely, and which formulas I personally recommend—available right here on Cosmetology.co.za.
🌟 What is Retinol?
Retinol is a derivative of Vitamin A—a powerhouse ingredient that’s been studied and loved for decades in the dermatology world. It belongs to a group of compounds called retinoids, which includes both prescription and over-the-counter versions.
Here’s what makes retinol so legendary:
- Speeds up cell turnover, revealing fresher skin underneath
- Boosts collagen production to reduce fine lines and wrinkles
- Unclogs pores to treat and prevent acne
- Fades hyperpigmentation and evens out skin tone
- Improves overall skin texture and radiance
It’s a multitasker in every sense.
✨ Benefits of Using Retinol
Let’s get into the glow-up you can expect when using retinol consistently:
1. Anti-Ageing Benefits
Retinol stimulates collagen and elastin production—two proteins that keep skin firm and youthful. Studies show long-term use can:
- Reduce the appearance of wrinkles by 44% in 12 weeks (source: PubMed)
- Visibly improve skin firmness and smoothness
2. Clearer Skin
Retinol helps prevent clogged pores and reduces inflammation, making it a go-to for:
- Hormonal breakouts
- Adult acne
- Post-acne marks
3. Fades Dark Marks and Scarring
It fades PIH (post-inflammatory hyperpigmentation) and sunspots by increasing cell turnover and breaking up melanin clusters.
4. Improves Skin Texture
Smooths roughness, minimises large pores, and leaves skin visibly softer and more refined.
🧴 How to Use Retinol in Your Routine
Start Slow. Go Low.
Retinol is potent—and while that’s a good thing, it also means it needs to be introduced gently.
Here’s how to ease it in:
- Start with 2–3 times a week, on alternate nights
- Use a pea-sized amount (less is more!)
- Follow with a barrier-repairing moisturiser
- Always wear SPF 50 the next morning—non-negotiable
Pro tip: If you’re prone to sensitivity, buffer your retinol by applying moisturiser before and after your retinol.

Do:
- Introduce slowly and observe how your skin reacts
- Keep your skin hydrated and nourished
- Take a break if irritation flares up

Need more proof it works? According to a study in the Journal of Cosmetic Dermatology:

❓ FAQ: Your Retinol Questions, Answered
Q: Can I use retinol if I have sensitive skin?
A: Yes—start with a gentler version like retinyl palmitate or retinaldehyde, and buffer it with moisturiser.
Q: What age should I start using retinol?
A: Mid-20s is ideal, but it’s never too late to start.
Q: Can I use it with Vitamin C?
A: Use Vitamin C in the morning and retinol at night for best results—unless your skin is well-adjusted.
Q: What if I break out when I start retinol?
A: That’s called purging—a temporary phase where breakouts may increase as cell turnover speeds up. It usually clears in 2–6 weeks.

A: No—retinoids should be avoided during pregnancy and breastfeeding. Always consult your doctor.
