This formulation combines two forms of next-generation retinoid actives in a combined concentration of 2% by weight:

These two actives are:

a) Solubilized Hydroxypinacolone Retinoate is a highly-advanced form of retinoid which is, in fact, a non-prescription ester of all-trans direct retinoic acid that offers a multi-fold better effect against signs of ageing than retinol, retinyl palmitate and nearly all other forms of non-prescription retinoid;

b) a sustained-delivery form of pure retinol in a protective capsule system which supports both the delivery and the effect of Solubilized Hydroxypinacolone Retinoate.

Both forms of retinoid used avoid the irritation associated with retinoid (including retinol) use while delivering better visible results against signs of ageing.

This product uses next-generation retinoid active technologies which have been shown to achieve better reduction in signs of ageing than retinol without irritation. These technologies cannot be compared directly with retinol itself in terms of concentration because they include a different retinoid molecule, in a similar way that Retinol cannot be compared with Retinoic Acid in terms of concentration. If you have interest in a retinol product, please refer to our Retinol portfolio above which products contain pure retinol and cost less since many retinol technologies cost less than their next-generation counterparts like Granactive Retinoid.

The Ordinary’s extended portfolio of retinoids includes the following formulations:

Granactive Retinoid 2% in Squalane (Moderate Strength, No Irritation)

Granactive Retinoid 5% in Squalane (High Strength, No to Low Irritation)

Retinol 0.2% in Squalane (Low Strength, Moderate Irritation)

Retinol 0.5% in Squalane (Moderate Strength, High Irritation)

Retinol 1% in Squalane (High Strength, Very High Irritation)

While the new offerings of Granactive Retinoid in Squalane offer a very-light-weight solution for better compatibility with several steps in a regimen, the existing formula continues to be a creamy hydrating emulsion for those who prefer this format.

Caution: Retinoids can make the skin more sensitive to UV radiation. Sun protection is particularly important when using retinoids. This product must not be used in conjunction with other retinoids including retinol or retinoic acid. This product is not a treatment for acne. Acne-prone skin may experience a temporary increase in acne during the first few weeks of using any form of retinoid including those used in this formulation.
