Retinol is a cousin to retinoid, a derivative of vitamin A used in skincare products. Retinoid products are available by prescription for:
Treating acne.
Treating psoriasis.
Reducing fine lines and wrinkles.
Reducing hyperpigmentation.
Improving skin texture
Retinoids come in various forms (and names) depending on their use. Here are the three most common ones for skincare:
Tretinoin (also known as Retin-A) is a topical retinoid cream used for mild acne and as an anti-aging treatment. This requires a prescription.
Isotretinoin sounds similar, but it’s an oral pill and a powerful retinoid that treats severe acne. This too requires a prescription.
Retinol is a weaker form of retinoid. It has similar cosmetic advantages, but it’s available in over-the-counter products. You don’t need a prescription for products made with retinol.
