Retinol or retinoid? What's the difference?
Retinoids are widely known for their ability to fight age-related symptoms such as wrinkles, fine lines, enlarged pores and loss of skin elasticity. These active ingredients are effective in improving the texture of the skin, supporting the generation of the necessary structural components of the skin and the natural processes of renewal and exfoliation. They are also suitable for the treatment of acne: normalize keratinization, reduce sebum secretion, help get rid of comedones and clogged pores.

Retinoids are a group of ingredients that are both natural and synthetic derivatives of vitamin A. Cosmetics usually use retinoids such as retinaldehyde, retinol and retinol esters, all of which are precursors of retinoic acid.

Retinoic acid is an active form of vitamin A that has the ability to bind to skin receptors. All other forms of retinoids do not have this connection, and in order to begin to act, they must undergo a path of transformation. For example: retinol → retinaldehyde → retinoic acid. But since this is an indirect reaction, the result is different on different skin. Retinol may not work simply because the skin is too lazy to turn it into an active form.
Granactive retinoid (Hydroxypinacolone Retinoate) is an innovative member of the retinoid family that binds directly to the retinoid receptors of cells and begins to work, but, unlike retinol, acts gently and does not irritate the skin, so its use is possible in higher concentrations and without a period of habituation.

A guide for anyone looking to start retinol:

Start with the lowest concentration - 0.2%
Apply not daily, but several times a week, gradually increasing the frequency.
Monitor the condition of the skin. Irritated, red skin, itching - clear signs that you need to reduce the frequency of application or concentration - can be diluted with cream or oil.
Do not use exfoliating acids, desiccants with alcohol content and cleaning agents with surfactants at the same time.
Moisturize the skin and maintain its protective barrier.
