1 What is retinol?
Retinol (a class of retinoids) is known to be a derivative of Vitamin A. They work by neutralizing free radicals present in the skin, which can cause damage to collagen cells.
It brings many benefits to the skin, especially the following four uses:
- Treatment of melasma helps to regulate skin color because vitamin A extract reduces the amount of melanin pigment in the skin, the culprit that causes pigmentation disorders, melasma, freckles or darkening on the skin, giving the skin an even and bright color.
- Anti – oxidant , anti-aging. Regenerate cells, nourish healthy skin from the inside.
- Strengthens resistance, regenerates the protective barrier for healthy, smooth skin.
- Support acne treatment , anti-inflammatory and prevent acne recurrence.
How does retinol work so well on the skin?
To prevent aging and protect the skin, in addition to moisturizing and sun protection, the supply of ingredients that help produce collagen for the skin is also essential. At this point, retinol is the perfect solution for your skin. However, if you use cosmetics incorrectly, it can cause skin irritation and affect more or less. So, here are some ways to get retinol to work well on your skin!
Full sun protection
Retinol makes the skin sensitive to the sun, so it is important to use the right amount of sunscreen to avoid damage to the skin.
Precautions before using retinol
Do not use retinol immediately after washing your face. After washing the face, the skin will lose a significant amount of the skin barrier, if using immediately retinol will be sore, red. It is recommended to use toner first, then retinol and other skin care steps.
Always dry the skin before applying retinol products to the skin because retinol can react with water making it more active, thereby causing severe skin irritation.
Combined with products to note
You can use the same AHA/BHA ingredients in your skin care routine: After using AHA/BHA, you should not immediately use products containing retinol, but wait 20-30 minutes. Make sure your skin is dry before use
Ideal time to use:
At night before bed, if your skin is too sensitive or dry, you can combine retinol with a moisturizer or serum. Don't forget to do it regularly and properly to get the best results.
Use the right amount
Using too much retinol does not make the skin beautiful faster but also makes it easier to irritate, so a pea for the entire face is enough.
You have to be patient to get the results you want
It takes a long time for the skin to get used to the Retinol and the right concentration, the time to achieve the best results is 1 year. As mentioned above, you have to slowly let your skin get used to each appropriate concentration, so it will take a long time for your skin to have noticeable changes. The average time to notice a change is usually 10-12 weeks and depending on the skin condition can be 2-3 months, the time to achieve the best results is 1 year.
3 Types of retinol suitable for each skin type
Retinol is more popular with users because it is less irritating than other derivatives. To see a noticeable effect, a concentration of 0.1% is most appropriate, while those who are new to retinol can choose a concentration of 0.01% or 0.03%. In the long run, you can increase the concentration to 0.5%, even 1%.
For sensitive skin
"Due to the potential for irritation, skin, especially sensitive skin, needs to be acclimated to retinol slowly," says dermatologist and Skinfluence founder Dr. Marina Peredo. "By using different concentrations of retinol, we can safely and effectively help the skin adapt with almost no irritation."
Thin and sensitive skin types who have never used a retinol should start at a low percentage, like 0.025%. And if your skin adapts well to the product after a few weeks of use, you can switch to a stronger one.
For normal and combination skin
Normal and combination skin can start with a higher concentration, 0.3% retinol. And depending on your skin's response, increase to a higher concentration for a few months. "When starting out, always watch for side effects, which may include redness, dryness, itching, or general sensitivity."
For healthy skin
"Darker, thicker skin types, will be a little more accommodating at the start of use." Let's start with a concentration of 0.5%. Once your skin has adapted, try a product with 1.0% retinol.

If, after 24 hours, you see that the skin on the hands that has been applied Retinol does not have any signs, we can completely rest assured to apply Retinol products to the face.

4 Notes when using products containing retinol
Note when using with other special treatments
RETINOL WITH OLD VITAMINS
Combining the use of retinol and vitamin C has received mixed reviews. Previous views have suggested that the acidic pH necessary for vitamin C's action contributes to the reduction of retinol's effectiveness. However, recent studies show that the combination of Retinol and Vitamin C not only deactivates each ingredient, but can also increase the ability to fight free radicals and effectively improve aging skin.
RETINOL WITH AHA/BHA
HA / BHA has the effect of purifying pores and helping the skin to remove old cells. Retinol is a powerful anti-aging agent. If used separately, each type will help your skin regenerate extremely well. Both groups of ingredients are strong active ingredients, if the skin is weak, it can immediately react with redness, peeling, even burning pain.
So, once your skin has gotten used to the retinol and you want to step up your treatment, you can use an AHA/BHA in the morning and a retinol at night. In addition, you can completely exfoliate with AHA / BHA before using Retinol to promote its effect (should only be applied to really healthy skin). But either way, you should still use moisturizer and adequate sun protection for your skin.
How to properly store retinol for effective results?
If you decide to use Retinol in your skin care routine, then you must know how to preserve this sensitive ingredient. Similar to other cosmetics, Retinol is also recommended to be stored in a cool place and out of direct sunlight. Retinol can be stored in the refrigerator. However, you should arrange cosmetics in separate boxes separate from fresh foods to avoid cross-contamination.
Time to use Retinol after opening the cap
Expiry date and actual shelf life are two completely different concepts. After opening, environmental factors can affect and change product quality and shorten the shelf life to ⅓ compared to the shelf life on the package. Specifically, when the original packaging is still intact, retinol will still be effective for about 1-3 years depending on storage conditions. Once opened, retinol should only be used for up to 12 months.
The proper use of retinol will bring high efficiency, but if abused, it can cause side effects.
In addition, it is necessary to limit the use of Retinol with some subjects as follows:
- Women in early pregnancy should not use products containing retinol. They can increase the risk of birth defects and cause miscarriage.
- People with sensitive skin to Vitamin A extracts , before using, try applying a little product containing Retinol to your hands, leave for about 10 minutes if there is no abnormality before continuing to use.
