Hi, it is Lee, YongSeok from Jfeel Clinic We changed the studio for 2022 last time And you guys liked it So I will film today’s video at this new studio again Today, I am going to explain about retinol Retinol was a very innovative product for those

who want to take care of their skin without meeting a dermatologist Or for those who want to fill collagen And for those who are worrying about the skin photoaging Before naturalism became a trend, Retinol was one of the wrinkle care ingredients which was widely used Some people say that if you use cosmetics containing retinol

You won’t need any other procedures like Botox, filler, or lifting Is this real? I will check the truth throughout the Q&A today. Is retinol and retino acid the same? Both ingredients are kinds of retinoids So they are both effective to create collagen,And improve wrinkles and pigmentation

But if you don’t know the differences like effects and the method of use, you might waste cost as well as cause side effects So you need to understand them thoroughly Today, I am going to explain about retinol and retinoid acid easily and precisely What is retinol?

Retinol is vitamin A, if I make it easier It has to become retinoic acid on the skin for the effect that we want But because retinol is easy to be transmitted and unstable, it is only used for cosmetics since its effect is not approved It is not guaranteed to be metabolized to retinoic acid as well.

To overcome these limits, you can see, among the wrinkle care cosmetics, The products containing retinol are bottled in black airtight containers, And use containers minimizing air contact rather than Opening-lid types. What's the effect of retinoic acid? Retinoic acid has been researched for long time To care the acne and skin aging.

Especially, the tretinoin among the retinoid acid is approved by FDA as a treatment for the skin photoaging Retinoic acid normalize the epidermis, create collagen in the derma, and eliminate the pigmentation. So if you continue to use it, your fine wrinkles will disappear, And your skin tone will become brighter and smooth.

This is why it is nicknamed a medicine for the skin. But since it could be a trouble if you use it wrong, You have to apply it after consulting with an expert. Which one is more effective, retinol or retinoic acid? Retinoic acid is a medicine, and retinol is a cosmetics So you can see which is more effective right away through this fact Still, let’s look through them more scientifically

In the study of Duell, 1997, the retinol’s cellular and molecular change The effect of retinol was 10 to 20 times weaker Than retinoid acid In other words, retinoid acid was shown to be more effective. Also, there was a study comparing retinol and retinoic acid 0.1% after applying them to human’s arm The increased range of skin epidermis and the collagen in the derma was much higher in retinoid acid than in retinol

However, retinol also has strength Which is, since it is absorbed to skin much better Than the retinoid acid, Most people think that the actual difference would not be as big as ten times. So I think we should see how things would go. Where can I buy Retino? In the case of retinoic acid, the tretinoin ointment is representative these days Which is the Steva A cream

Because it is a prescription based medicine, you need a prescription to buy it And you can buy it only at the pharmacy. Stieva A cream is divided into four types which are 0.01%, the lowest, 0.0025%, 0.05%, and 0.1%, the highest. 0.1%, the highest type, is not imported to Korea yet. Why isn't retino acid a cosmetic product? As effective as it is, retinoid acid is stimulating

That’s why it is sorted as medicine so that you can use it Under the prescription of an expert. In practice, the irritation that can be caused by retinoic acid is much stronger, so the excessive absorption of retinoic acid can cause irritant skin rash, bulges, stinging, heat, et cetera, It is important to use it right and carefully Precautions for using retinol. The weakness of retinoid acid is the irritation

and increase the concentration gradually For example, it is better to start with 0.01% and change it to 0.025 gradually And to decrease the interval gradually, like starting with once a three day moving to once a day And even though you are using the low concentration, if you think It is too stimulating, it is good to apply it with moisturizer or oil

I recommend applying a very small amount of it around the eyes because It is easy to be absorbed and stimulated there since the skin is thin there. How to use retinol and retino acid. Now, for this one, I think it is better to divide it into three parts First, apply it at night If it is exposed to ultraviolet rays after use, there can be no effect

due to the transmutation Second, use moisturizer Because ceramide synthesis could be drop temporarily,and the skin can become dry and flaky Third, apply sunscreen. Because the cuticles become denser and thinner, it is easy to be sensitive to sunlight and get stimulation I don’t mean to apply sunscreen with retinoid acid,

Apply retinol or retinoic acid at night And always apply sunscreen Before you go to work or go out. Check if the content of retinol is higher than 2,500IU/g And you must check if the product used ingredients like retinal palmitate instead of retinoid unlike it’s description Buy products in an airtight container not to expose the content to sunlight

It’s better to buy a small amount of the latest product and use it quickly. How was it? Today, I have explained the way you can take care of your skin at home instead of meeting a dermatologist by using retinol and retinoic acid product, which can create collagen at home, improve the fine wrinkles, and be effective for the skin photoaging again.
