All forms of OTC retinoids goes through a conversion line until it can become effective. The final step of conversion is retinoic acid; retinoic acid IS Tretinoin.
This is why tretinoin is so effective; it gets to work immediately on the skin.
Research on tretinoin has found it to be incredibly effective for reducing the signs of aging. It helps improve damage from the sun, even the skin tone, and smooth out wrinkles. It is also an effective acne treatment by reducing and balancing out sebum production in pores.
Tretinoin, like other forms of Vitamin A, increases the turnover cycle of skin cells. This helps the skin create newer and healthier skin cells faster.
