Retinol: the established option
Retinol is a vitamin A derivative with a long track record for encouraging cell turnover and supporting collagen production, which is why it's a common ingredient in serums aimed at texture and fine lines. In this dataset, retinol-labelled serums range from around £5.50 (Simple Daily Face Serum) to roughly £26 (Eucerin Overnight Face Serum), so it is not an ingredient limited to premium pricing. The trade-off is tolerability: retinol commonly causes dryness, peeling and sun sensitivity, especially in the first few weeks.
Bakuchiol: positioned as the gentler alternative
Bakuchiol is a plant-derived compound often marketed as a retinol alternative for people who find retinol too irritating. Early research suggests some overlapping effects on skin texture with less reported irritation, though the evidence base is considerably smaller and less mature than retinol's — this is a newer ingredient with far fewer long-term studies behind it, not an established equivalent.
Irritation is the real deciding factor
For most people starting out, the honest question isn't which ingredient is 'stronger' but which one their skin can tolerate consistently. A product used twice a week without irritation beats a more potent one abandoned after a fortnight of redness. If you have used retinoids before without issue, retinol is the better-evidenced choice. If you have reactive, sensitive skin or have struggled with retinol previously, bakuchiol is worth trying instead.
How to introduce either one
Start at two to three nights a week, applied to dry skin, followed by moisturiser. Increase frequency only once skin tolerates the lower frequency without flaking or persistent redness. Both ingredients are typically used at night, and both increase the practical importance of daily sunscreen — this is not optional alongside either ingredient, since new skin cells are more vulnerable to UV damage.
What not to combine them with
Avoid layering retinol with strong acid exfoliants (AHA/BHA) or vitamin C in the same routine to start with — the combination increases irritation risk without a clear added benefit for most people. Bakuchiol is generally considered easier to combine with other actives, which is part of its appeal, though 'gentler' still isn't the same as 'inert'.
Pregnancy and medical situations
Retinoids are generally advised against during pregnancy and breastfeeding; this is a question for a pharmacist, GP or dermatologist, not a shopping site. If that applies to you, it's one of the more common practical reasons people look at bakuchiol specifically, since it does not carry the same advice.

Frequently asked questions
- Is bakuchiol as effective as retinol?
- Some early studies suggest overlapping benefits for skin texture, but the evidence for bakuchiol is much thinner than the decades of research behind retinol. Treat it as a gentler option worth trying, not a proven equivalent.
- Can I use retinol and bakuchiol together?
- There's no strong reason to combine them, and doing so adds complexity without clear extra benefit. Most people are better off choosing one and giving it a proper trial before considering a change.
- Why does retinol cause peeling?
- It speeds up cell turnover, which can outpace the skin's ability to adjust in the first few weeks. This settles for most people with consistent, lower-frequency use — it isn't usually a sign the product is unsuitable.
- Do I still need sunscreen if I only use these at night?
- Yes. Both ingredients affect the skin cells present the following day, which makes them more vulnerable to UV damage regardless of when the product was applied.
