Tretinoin is a retinoid that improves fine and coarse wrinkles by restoring dermal collagen and decreases the darkness of brown spots by reducing epidermal pigmentation. Retinoids are a derivative of vitamin A and they have a wide range of benefits. They help to unclog pores and increase the cell turnover of the skin.
More powerful than over the counter anti-aging creams, Tretinoin delivers visible results that help restore deterioration caused by age and sun damage. You can read more about it here https://www.dermatica.co.uk/medicines/tretinoin
