“Retinoid” is the umbrella term that describes all of the vitamin A derived ingredients we see in skincare, including both prescription and over-the-counter retinol products. Retinol is just one of a type of compound called
retinoids, which come in many forms.
Tretinoin
Tretinoin is a prescription topical retinoid. In its mildest formulations, it’s used for its
anti-ageing properties. Stronger formulations are used for acne.
Adapalene
Adapalene is another prescription retinoid that is commonly used to treat acne. It is known for its anti-inflammatory effect and low absorption rate through human skin. Adapalene is less potent than tretinoin, but tends to cause less skin irritation.
Retinol
Retinol is a milder form of retinoid and needs retinaldehyde to convert to retinoic acid for it to work. It is advised for
anti-ageing and does not benefit active acne. It is commonly found in over-the-counter products.
Plant-based retinol alternatives
Organic Harungana extract is a plant-derived alternative to retinol. According to Clarins Research, Organic Harungana has the same mechanisms as retinol, and is just as effective for anti-ageing and pro-collagen synthesis properties. This exclusive Clarins natural active ingredient was selected from several candidates not only for its ‘retinol-like’ effect, but also for its tolerance on the skin and its non-photosensitivity. Organic Harungana is a good alternative to retinol for people with sensitive skin.
