Retinol or Bakuchiol? Differences, Tolerance and How to Choose

Short answer: retinol has far more research behind it and is the choice with the strongest evidence, but it needs a slow introduction and often causes dryness or stinging at first. Bakuchiol has fewer studies, tends to be easier to tolerate and can be a sensible starting point for sensitive skin or for anyone who has already given up on retinol. The best choice is the one your skin tolerates and you can use consistently.

Bakuchiol is often sold as "natural retinol". The comparison sells, but it isn't accurate: they are different ingredients, with different mechanisms and very different amounts of evidence.

What is retinol?

Retinol is a vitamin A derivative. In the skin it is converted, step by step, into the active form that acts on skin renewal processes. It is one of the most studied cosmetic ingredients for the appearance of fine lines, uneven texture and uneven tone.

The trade-off is tolerance. Especially at the start, it can cause dryness, flaking, redness or stinging, particularly if you start too fast or your skin barrier is already compromised. Concentration and formulation change the experience a great deal.

What is bakuchiol?

Bakuchiol is a compound obtained from the seeds of the Psoralea corylifolia plant. It is not a retinoid: its chemical structure is different. It became popular because studies have associated it with cosmetic benefits similar to retinol's, with less irritation.

The research is promising, but the number and size of studies are far smaller than for retinol. "Gentler" doesn't mean "can't irritate": any new cosmetic can cause discomfort.

What the most-cited study says

The usual reference is Dhaliwal et al. (2019), published in the British Journal of Dermatology: a randomised, double-blind trial with 44 participants over 12 weeks, comparing 0.5% bakuchiol (twice daily) with 0.5% retinol (once daily). The authors found no statistically significant difference between the groups in wrinkle surface area and hyperpigmentation; the retinol group reported more scaling and stinging.

It's important to read this with the right limits: it is a single study, with a small sample and specific formulas. It does not compare bakuchiol with prescription retinoids, and the results don't automatically transfer to other products with other concentrations and formulas.

Retinol or bakuchiol: comparison

• Evidence — retinol: well established; bakuchiol: promising but limited.
• Initial tolerance — retinol: dryness and flaking are common; bakuchiol: generally more comfortable.
• When to use — retinol: at night; bakuchiol: morning or night, depending on the formula.
• Introduction — gradual for both.
• Daily sunscreen — essential in both cases.

When each one makes sense

Retinol makes sense if your skin usually tolerates actives well, if you value the more extensive evidence and if you're prepared to introduce it carefully.

Bakuchiol can be a sensible starting point if your skin reacts easily, if you're simplifying your routine or if you've already given up on retinol because of discomfort.

During pregnancy or breastfeeding, retinoids are usually avoided. Any change to your routine at that time, including bakuchiol, should be decided with a healthcare professional.

How to start without overloading your skin

Before introducing either, stabilise the basics: gentle cleansing, a suitable moisturiser and daily sunscreen.

If you choose retinol

Apply at night, on clean, dry skin, two nights a week to begin with. If your skin stays comfortable, increase gradually, following the product's instructions. Avoid the corners of the nose, the eye area and the lips. With sensitive skin, you can apply a thin layer of moisturiser first.

If you choose bakuchiol

Follow the product's instructions: bakuchiol comes in serums, oils and creams with different directions. Starting every other day helps you see how your skin responds.

Combinations to avoid at first

Don't start retinol, bakuchiol, acid exfoliants and vitamin C in the same week. Introduce one product at a time. With retinol, don't use exfoliants on the same night while your skin adjusts.

Signs to slow down

Persistent stinging, marked redness or flaking are not required signs that something is working. Reduce frequency, moisturise more or take a break. If the discomfort persists, seek advice from a healthcare professional.

FAQ

Is bakuchiol a natural retinol?

No. It's a different ingredient with a different chemical structure. It has been compared with retinol in studies, but it is not a retinoid.

Can I use bakuchiol in the morning?

Many formulas can be used morning or night. Follow the product's instructions and always finish your daytime routine with sunscreen.

Can I use bakuchiol with acids or vitamin C?

They can be part of the same routine, but with sensitive skin it's more cautious to alternate nights or times of day and introduce one product at a time.

Which is better for beginners?

It depends on your skin. With reactive skin, bakuchiol is usually easier to introduce. With tolerant skin and the patience for a slow introduction, retinol has the more extensive evidence.
