What is the difference between retinol and a retinoid?
Retinoid is the general name for vitamin A derivatives. Retinol is a milder form in non-prescription products; prescription forms such as tretinoin are stronger.
Skin converts retinol first to retinaldehyde and then to the active form, so its effect is slower and usually gentler. Prescription retinoids act more directly, so irritation is more likely and medical follow-up is needed.
Labels show percentages and formula differences; a higher percentage does not always mean a better fit. Skin type and sensitivity decide.
What can retinoids do for skin?
They may support cell renewal and collagen synthesis, reduce pore congestion and acne tendency, and soften the look of fine lines and spots.
Effects usually appear over weeks to months, and skin may react in the first weeks. Results vary and the expected benefit shrinks without regular sun protection.
They are often mentioned for post-acne marks and photoageing. See the acne and skin ageing pages for more detail.
How do you start and manage side effects?
Starting a few evenings a week with a moisturiser is a common approach. If irritation occurs, frequency is reduced and a doctor is consulted.
A thin layer is usually applied in the evening to clean, dry skin, avoiding the eyes and lips. Using peeling acids, strong exfoliants or other irritating actives at the same time may increase irritation.
If there is marked burning, swelling, widespread redness or a possible allergy, stop the product and see a doctor. Self-treating complications is not advised.
Who should not use them, and what to watch for?
They should not be used during pregnancy, breastfeeding or when planning pregnancy. Active eczema, open wounds and recent isotretinoin use call for medical advice.
Retinoids can make skin more sensitive to sun. Daytime broad-spectrum sunscreen is needed and tanning beds should be avoided. If you plan a laser, peel or similar procedure, tell your doctor you use a retinoid; a pause beforehand may be discussed.
The doctor or dermatologist decides which product and strength suit you. No dose or protocol is given on this page.
Frequently asked questions
Can retinol be used during pregnancy?
No, it is not recommended during pregnancy or breastfeeding. If you plan a pregnancy, speak to your doctor.
Can retinol be used in the morning?
Most products are used in the evening because light sensitivity can increase. Sunscreen must be used in the morning.
How long does retinol take to work?
Effects are usually seen over weeks to months; they vary and no set time can be promised.
Can retinol be used with vitamin C?
Usually one is used in the morning and the other in the evening. Using them together may irritate sensitive skin.
