How To Start Using Retinol Without It Ruining Your Skin — The Honest Beginner Guide
I started using retinol wrong the first time. I bought a product, applied it nightly as the instructions suggested, and had the specific experience of red, flaking, sensitive skin that the retinol introduction guides warn about and that I’d dismissed as applying to people with more sensitive skin than mine.
The flaking and redness lasted ten days. I stopped, let my skin recover, and started again with a more cautious approach that produced the results retinol is supposed to produce without the skin barrier disruption that undermines everything else in a skincare routine.
Why Retinol Causes Irritation And What That Actually Means
Retinol is converted by the skin into retinoic acid, the active form that produces the benefits — accelerated cell turnover, reduced fine lines, improved texture, faded hyperpigmentation. The skin’s ability to tolerate this conversion at the rate retinol produces it depends on how much retinol the skin has been exposed to previously, which for most beginners is none.
The irritation (redness, flaking, sensitivity) is the skin adjusting to a rate of cell turnover it hasn’t previously experienced. Starting at a lower concentration and lower frequency gives the skin time to build this tolerance rather than overwhelming it immediately.
The Protocol That Works
Week 1-2: Once per week, at night only. The Ordinary Retinol 0.2% in Squalane (£7-10) is the starting point — the lowest effective concentration in a hydrating squalane base that reduces irritation.
Week 3-4: If no significant irritation (some mild tingling is normal; redness, flaking, and sensitivity are signals to go slower), increase to twice per week.
Month 2: Increase to every other night if tolerance is established.
Month 3 onwards: Increase toward nightly use at the original concentration before increasing the percentage.
The Specific Products Worth Knowing
The most accessible starting retinol for the price. The 0.2% concentration is the lowest effective concentration and the squalane base provides hydration that reduces the dryness that retinol use can produce.

After establishing tolerance at 0.2-0.5% over two to three months, the Paula’s Choice 1% Retinol is the product to progress to. The 1% concentration is at the upper end of over-the-counter retinol and produces more significant results than lower concentrations for established users.
Price: £54-62

The eye area is thinner and more sensitive than the rest of the face and benefits from a specifically formulated retinol rather than applying face retinol near the eye. The RoC Retinol Correxion is the accessible option with the appropriate concentration for the delicate eye area.

The Three Rules That Prevent Problems
Always use SPF the morning after retinol application. Retinol increases photosensitivity — UV exposure after retinol application without SPF protection produces the exact damage retinol is trying to reverse.
Moisturise after retinol. The dryness that retinol produces is a barrier function change. Applying a good moisturiser after retinol seals the retinol in and reduces the dryness that produces flaking.
Never combine with other actives at the start. Vitamin C in the morning, retinol at night — not on the same application. AHAs and retinol on the same night — not at the start, when tolerance is being built.
