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. Introducing vitamin A into your routine gradually is the best way to avoid irritation.
Retinal is less potent than prescription strength but more potent than retinol; however, it's really hard to find in a formulation you can use. There are very few products out there containing retinal, so they're not very popular or widely marketed.
“The great news is that retinal also doesn't cause any more irritation to the skin than retinol—just quicker, more powerful results." In short, this means that retinal gets to work more quickly than retinol (think of it this way—the fewer stops a train has to make, the quicker it reaches its destination).
Retinol is found in numerous over-the-counter (OTC) skin care products. 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.
Both retinol and Retin-A can help keep acne from forming. The difference is that Retin-A is a prescription medication that has been FDA-approved to treat acne, while retinol is found in numerous over-the-counter (OTC) skin care products.
The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that receive and organize visual information. Your retina sends this information to your brain through your optic nerve, enabling you to see.
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  due to its chemical toxicity in randomly modifying proteins through Schiff base formation.
Tretinoin is an effective long-term treatment for acne. While it won't work for everyone, studies show that it encourages cell turnover that can even your skin tone, treat breakouts, and decrease the appearance of acne scarring.
Retin-A is the brand name for the medication Tretinoin. Retin-A is a synthetic form of vitamin A and it's available only through prescription. Tretinoin is retinoic acid and is considered an active ingredient.
Retin-A Micro is a costlier, time-released version that is available only as a gel. It is less likely to cause irritation and dryness and can be applied immediately after cleansing. However, it may not be as effective as Retin-A cream for anti-aging treatments and may be better suited than creams for oilier skin types.
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.
Tretinoin gel, cream, or lotion requires a prescription because it's more powerful than retinol. Doctors prescribe tretinoin to treat skin conditions like: Acne. Psoriasis.
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.
If you stop using the medication or are inconsistent with your treatment, any improvements you see may disappear over time. Always use the product as prescribed by your healthcare provider (Rodan, 2016).
Tretinoin is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Tretinoin is classified as a "retinoid." (For more detail, see "How Tretinoin Works" section below).
Tretinoin (Retin-A, Avita, Renova) is a derivative of Vitamin A and is the treatment of choice for comedonal acne, or whiteheads and blackheads. It works by increasing skin cell turnover promoting the extrusion of the plugged material in the follicle. It also prevents the formation of new comedones.
Retin-A can improve skin texture and fade dark spots and freckles because it causes skin cells to turn over more rapidly. It shrinks dilated pores and improves cell turnover within the pores so they are less likely to clog and become blackheads and whiteheads.
Retinal flat cells are a substrate that facilitates retinal neuron growth and fiber formation. Invest Ophthalmol Vis Sci. 1986 Mar;27(3):296-306.
In mammals, the biosynthesis of retinoic acid from retinol occurs by two sequential enzyme reactions: retinol is converted to retinal by the oxidation reaction of retinol dehydrogenase, and retinal is then converted to retinoic acid by the additional oxidation of retinal dehydrogenase (RALDH), which belongs to the ...
If retinal damage is not treated properly and in a timely manner, permanent vision loss may occur. If you experience any symptoms of a damaged retina, contact Associated Retina Consultants at 602-242-4928 or website right away.
The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture.
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
A number of side effects to retinoid treatment have been recorded; one group of such side effects relates to eyes and vision. Dry eye syndrome and blepharoconjunctivitis are the most common side effects, appearing in 20-50 % of patients treated with retinoids.
Use just a pea-sized portion.
Dab a bit from this portion onto your forehead, cheeks, and chin, then smooth it around. Use another pea-sized portion for your neck or chest if you need to apply in those areas, too.
