What is retinol?
A form of vitamin A, retinol
or retinoic acid, is clinically proven to improve the appearance of aging skin, acne, and skin discoloration. Retinol helps promote cell turnover, improve the appearance of fine lines and wrinkles
, skin discoloration
, and blemishes
. When applied to the skin, retinol converts to retinoic acid and is often considered a more tolerable form of vitamin A.
How does retinol benefit my skin?
With age, skin’s natural cell turnover decreases resulting in dull, uneven skin tone
and rough skin texture. Topical retinol creams help promote turnover of surface cells, which means dead skin cells are sloughed away faster, revealing visibly healthier and brighter skin. Similarly, retinol’s exfoliation mechanism helps improve the appearance of blemishes by preventing dead skin cells from clogging pores.
Purity is essential for retinol efficacy in skin, as pure retinol most easily converts to retinoic acid in skin. Always look for high concentration of pure retinol
vs. retinol derivatives such as retinyl palmitate. SkinCeuticals uses pure, high concentrations of retinol enhanced with stabilization technology to ensure maximum conversion and efficacy.
Is retinol the same as tretinoin?
Retinol and tretinoin are both chemical compounds derived from vitamin A. Tretinoin is a pharmaceutical form of retinoic acid available only by prescription. It is frequently prescribed for acne, but also helps improve fine lines
, and skin discoloration
. Though highly effective, this topical treatment can cause unwanted side effects including redness, peeling, and dryness.1
Topical retinol, on the other hand, is available for purchase without a prescription as an over the counter (OTC) retinol cream. While it functions similarly to tretinoin, research has shown that it is potentially less irritating.2
For the appropriate recommendation on which form of vitamin A product is best suited to your specific skin needs, please consult a skincare professional.

Can I use retinol in the sun?
Pure retinol acts as a strong exfoliant, which can render skin sensitive to sun and UV damage. Therefore, it is recommended that retinol be applied in the evening and always be used in conjunction with a high broad spectrum sunscreen
during the day. Many physicians do not recommend retinol use during peak summer months.
Additionally, research shows that some retinol formulations can breakdown quickly if not in proper protective packaging. SkinCeuticals retinol night creams are packaged to ensure stability and protection of the product potency.
How to use retinol?
In the evening after cleansing
, apply a pea-sized amount to the tips of the fingers. Using too much retinol can irritate the skin. Dab the product onto your face, avoiding the eye area and massage firmly until it has absorbed into skin. For optimal results, allow for absorption before applying other skincare products. Limit initial use to once or twice a week, gradually increasing frequency to nightly as tolerated.
Due to the high concentration of pure retinol in SkinCeuticals products, use a retinol cream only at night to limit photosensitivity and irritation. Always apply a broad spectrum sunscreen
during the day when using this product.
When to avoid retinol?
Due to its exfoliating mechanism of action, topical retinol creams may increase skin sensitivity and potential for irritation, especially when used with certain medications or
. As retinol creams can increase photosensitivity, extensive periods of sun exposure are not encouraged. It is especially important to apply a broad spectrum sunscreen while using this product. Vitamin A products like tretinoin and retinol are not recommended during pregnancy. Please consult a physician
to determine whether the use of a retinol cream is appropriate for you.
Can retinol help with acne?
To understand how retinol helps reduce
, it is important to understand how acne formation is triggered in the first place. Skin’s pores contain oil glands, which are responsible for producing oil to lubricate the skin and hair. Usually, oil glands produce the right amount of sebum or oil, but they can be overactive at times, resulting in excess sebum production. The combination of excess oil and dead skin cells can cause pores to become clogged, creating the perfect condition for P.acnes bacteria – a bacteria that can contribute to the formation of acne – to become trapped and multiply.
Topical retinol formulations increase cell turnover in skin, ultimately reducing the buildup of dead skin cells. With fewer dead skin cells present on the surface of the skin, it becomes more difficult for pores to clog. Retinol creams work via chemical exfoliation, which may be less abrasive than mechanical exfoliation that involves the use of scrubs.
However, as with any topical skincare products targeting
, results may take time. It is important that retinol and any other
are applied as recommended by your skincare professional. It is also essential that a
broad spectrum sunscreen
is applied daily when using a retinol. Look for non comedogenic, oil free sunscreen
formulations that deliver high UVA/UVB protection without clogging pores.
