“The result is that retinal acts up to 11 times faster than retinol when providing its anti-aging, anti-blemish, and radiance-boosting effects,” Dr. Shotter continues. “The great news is that retinal also doesn't cause any more irritation to the skin than retinol—just quicker, more powerful results."
Retinol vs retinal side effects
Technically speaking, retinol is usually gentler than retinal, but new developments in encapsulation techniques have allowed formulators to create retinal products that are just as kind to the skin as retinol.
Retinal is the closest thing you can get to prescription-strength vitamin A, which in its mildest form is tretinoin. Retinal can be more effective than retinol, but with the extra punch of power comes increased likelihood of skin sensitivity.
This problem is more prominent with tretinoin and tazarotene whereas other retinoids mainly represented by retinaldehyde and retinol are considerably less irritating. In order to minimize these side effects, various novel drug delivery systems have been developed.
Tretinoin is a more potent retinoid than retinol and will show results faster. While these active ingredients both combat signs of photoaging (aka wrinkles, rough skin, uneven skin tone, and enlarged pores), tretinoin-based products like Night Shift are more effective for fighting acne.
That's not all: In a study comparing . 05% retinal and . 05% retinoic acid, retinal was shown to be just as effective as the prescription-strength ingredient in reducing signs of photoaging, all while being significantly less irritating to the skin.
The difference between them is depth and speed! Retin-A penetrates immediately and into deeper layers of your skin to repair instantly. Retinol takes a while to penetrate and repair. They are both good quality anti-aging skin care products.
Retinal is the vitamin A derivative that is most toxic, due to its chemical reactivity. Even when vitamin A is used only for light sensing, retinal can be toxic [119] due to its chemical toxicity in randomly modifying proteins through Schiff base formation.
For the purposes of skin care, tretinoin can be thought of as a more concentrated version of retinol. This means that tretinoin is stronger than retinol. This difference in strength can help guide your decision-making when it comes to choosing a skin care product. Your skin is affected by more than what you put on it.
First, the answer is yes, retinol can make wrinkles worse, especially when you first start using it. What is happening is a drying effect, and one can get epidermal sliding from separation from the dermis.
Tretinoin It is a derivative of Vitamin A acid and is an effective slow bleaching agent that can be safely used in the eye area in an emollient cream base.
Retinoic Acid. As mentioned earlier, retinoic acid is the most potent form of retinoids. “This is the end point molecule that is biologically active on skin, and is therefore the strongest,” says Dr. Rabach.
The most common side effect of tretinoin use is a warm, stinging sensation in the skin directly after the medication is applied. This is often accompanied by dry and itchy skin, skin redness, mild scaling and a slight burning sensation.

Can a detached retina heal on its own? Very rarely, retinal detachments are not noticed by the patient and can heal on their own. The vast majority of retinal detachments progress to irreversible vision loss if left untreated so it is important to monitor any changes noticed in your vision.
“Studies suggest you need to use at least 0.25% retinol or 0.025% tretinoin to be effective, so I recommend using a product that specifies the percentage.” When choosing a retinol product, Dr. Rogers says it's best to start with the lowest concentration before moving up. Another thing to consider is your skin type.
While prescription-strength retinoids may have an effect in a matter of weeks, it can take up to 6 months for OTC retinols to produce the same results. You may notice a difference in conditions like acne after 12 weeks, but sun damage and signs of aging can take much, much longer to improve.
Some of the main symptoms of retinol burn include: Dry skin. Skin sensitivity. Painful irritation.
Retinol burn may also occur depending on the formulation you're using and how often you're applying it. "Over-the-counter retinols tend to cause less irritation than prescription retinoids," says Chang. "It can take weeks for your skin to get used to them, so it's important to ease your way in.
Dry eye syndrome and blepharoconjunctivitis are the most common side effects, appearing in 20-50 % of patients treated with retinoids. They often contribute to the occurrence of other side-effects such as eye discomfort and contact lens intolerance.
Tretinoin (also known as Retin-A, Renova): “This is a prescription topical retinoid. In its mildest forms, it's used for its anti-aging properties.
It may seem surprising, but even small percentages of retinol can benefit your skin. Percentages of 0.01% retinol or greater are proven to be effective at improving multiple signs of ageing, reducing pore size and improving the overall health of your skin.
Should you use retinol under your eyes? Yes, definitely. While it is true that retinol – a form of vitamin A – is a powerful ingredient and the skin under your eyes is delicate, there's no reason why you should miss out on the amazing benefits of retinol.
In rare cases, tretinoin may cause side effects that require medical attention. If you're using tretinoin and experience eye redness and swelling, severe swelling or burning of the skin, or blistering, it's best to seek medical advice as soon as possible.
