Retinol vs Retinal: which is better

Retinal and retinol are two vitamin A derivatives used in cosmetics to improve the appearance of the skin. Above all to treat wrinkles, expression lines, uneven texture, and signs of photoaging. Although they belong to the same family, they are not exactly the same.

The main difference between retinal and retinol lies in the number of metabolic steps each needs to convert into retinoic acid, which is the form of vitamin A that acts on the skin's receptors. Retinol needs to be converted first into retinal and then into retinoic acid, while retinal only needs one conversion.

That is why, retinal is usually considered a more direct and more potent active ingredient than retinol at comparable concentrations, although this does not mean that any product with retinal is automatically more effective than any product with retinol. Concentration, formulation, stability, and individual tolerance are also determining factors.

Retinal vs retinol: main differences

In summary: retinal needs one less step to reach retinoic acid, so it can offer more direct activity. However, there is no universal equivalence between a percentage of retinal and one of retinol, so it is not correct to state that, for example, X % of retinal is exactly equivalent to Y % of retinol.

Retinal or retinol: which is better?

There is no universal answer to the question “retinal or retinol, which is better”. Both can be excellent cosmetic ingredients, and in fact both have clinical evidence regarding the improvement of different signs of photoaging. Thus, for example, it has been shown that continued use of either one provides improvements in lines, wrinkles, pigmentation, firmness, and elasticity.

The choice therefore depends on factors such as:

• Previous experience with retinoids. If you have already used retinol or other retinoids and your skin tolerates them well, retinal can help you achieve more visible results in less time. If you are just starting, a low-concentration retinol is usually a more gradual option.
• Skin sensitivity. More sensitive skin or skin prone to irritation usually benefits from gentle formulas and a gradual introduction.
• The cosmetic goal. If you are looking to improve wrinkles, firmness, texture, or dark spots, both retinal and retinol can be effective. The difference is usually more in the speed of the results and skin tolerance than in the goal itself.
• The concentration used. A product with a concentration suitable for your skin can offer better results than another apparently more potent ingredient that is poorly dosed or poorly tolerated.
• Product formulation and stability. Efficacy does not depend solely on the active ingredient. A well-designed formulation helps maintain the stability of the retinoid and helps the skin utilize it better.
• The frequency of application that can be tolerated. A product you can use consistently usually offers better long-term results than another more potent one that you have to discontinue due to irritation.

Is retinal more potent than retinol?

This is one of the most common questions when comparing retinal vs retinol. From a metabolic point of view, retinal is one step closer to retinoic acid, so it has a shorter conversion pathway. This makes it reasonable to consider it a more direct retinoid than retinol.

However, simply saying that “retinal is X times stronger than retinol” can be misleading. As we mentioned earlier, there is no universal retinal-retinol equivalence that allows you to directly convert their percentages. The actual activity depends on the concentration, formulation, ingredient stability, its release, and each skin's response.

That is why, if you are comparing two products, you should not decide solely by looking at the percentage shown on the packaging.

Retinal or retinol for sensitive skin

Keep in mind that these products are not indicated for sensitive skin. If you have sensitive or reactive skin, we recommend using the Cosmetic Booster. This item contains Retinyl Palmitate, so you can enjoy the benefits of retinoids without your skin looking irritated.
