Where Retinol wins
- • Retinol works by encouraging skin cell turnover, which is why it is associated with smoother-looking texture and a reduction in the visible appearance of fine lines with sustained use over weeks and months. It is converted by the skin into its active form in stages, which is part of why it tends to be gentler, if slower-acting, than stronger prescription retinoids. Results build gradually rather than immediately, and consistent use matters more than concentration.
Where Salicylic Acid wins
- • Salicylic acid works by loosening the bonds between dead skin cells on the surface and, because it is oil-soluble, it can also penetrate into oil-filled pores to help clear congestion from within. This combination makes it a common choice for blackheads, visible pores and general surface texture linked to excess oil. It is typically used in cleansers, toners and leave-on treatments at low, cosmetic-use concentrations, applied a few times a week rather than daily for most people.
Who should choose which
Retinol
Retinol is generally used by people wanting to address the visible signs of ageing or uneven texture, and is typically introduced slowly — for example, a couple of evenings a week — regardless of skin type. It is usually not recommended during pregnancy or while breastfeeding, and sensitive or very dry skin often needs a lower strength and a slower introduction to avoid excessive dryness or flaking.
Salicylic Acid
Salicylic acid tends to suit oily, combination and acne-prone skin, where excess oil and congested pores are the main concern. Because it is a chemical exfoliant, it is generally introduced cautiously on dry or sensitive skin, where it can be more drying than gentler options. It is not typically the first choice for skin that is already very dry or reactive.

Frequently asked questions
- Should I use retinol in the morning or evening?
- In the evening. Retinol degrades in sunlight and increases the skin's sensitivity to UV, so it is applied at night and always followed by sunscreen the next morning, without exception.
- Why is my skin flaking after starting retinol?
- Some initial dryness, redness or flaking is common as skin adjusts, particularly in the first few weeks. Using it less frequently, applying a moisturiser afterwards, and building up gradually usually settles this. Persistent or severe irritation is a reason to pause and seek advice.
- Can I use retinol while pregnant?
- It is generally advised against during pregnancy and breastfeeding as a precaution. Anyone who is pregnant, trying to conceive, or breastfeeding should speak to a doctor or midwife about which skincare actives are appropriate rather than relying on product packaging.
- How often should I use salicylic acid?
- Most people start with two or three times a week rather than daily, particularly with leave-on products, and build up gradually depending on how skin responds. A rinse-off cleanser containing salicylic acid can generally be used more often since contact time is short.
