Although there are better retinol creams out there, you really can't find one as good as this for the price. For one-half to one-third the price of most retinol creams, ROC works really well and is easy to use and apply. It does have a bit of fragrance to it, but it's nothing major and actually smells pretty good.

this product contains an effective form of Retinoids (vitamin A): retinol 2.00% - 3.10%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores.

Zeichner also suggests only using retinol at night. “The evening is a time of rest and repair, and cell turnover is at its peak,” he says. “For this reason, I recommend applying retinol before bed to enhance activities that are already happening.”

Apply retinol at night. Since you don't have to wash the retinol off after you put it on, you can let it absorb into your skin overnight while you're sleeping. Develop a regular skincare routine at night so you don't forget to apply retinol.

Side effects of using retinol may include:

• Redness.
• Irritation.
• Burning.
• Itching.
• Dry skin.
• Flaking and peeling of the skin.
• Increased sensitivity to the sun.
• Skin cancer.

But what percentage of retinol is effective? Look for formulations with a percentage between 0.3% and 1%, with retinol 1% being the strongest option. Our strongest products are Clinical 1% Retinol Treatment and 1% Retinol Booster.

Tretinoin is the more potent of the two, so it will show results faster. Retinol is an over-the-counter (OTC) retinoid that doesn't require a written prescription. It's the precursor to tretinoin and goes through several conversion steps before it becomes pure tretinoin.

Retinol also stimulates collagen production, which is another way it diminishes dark spots. Not only will dark spots be reduced, but wrinkles and sagging skin will also begin to diminish, and the effects of retinol products will continue to work just as effectively over time.

Retinol should always be applied at night. It's especially sensitive to light, which is why it's kept in dark packaging or packaging that doesn't let any light through. In order to avoid unnecessary sun damage, only ever apply retinol before you go to bed.
