Choosing a skin booster for dry skin


Hello.

I am Chief Director Kim Jang-ju.

During times like these when the weather is getting dry,

the skin can easily become rough and elasticity noticeably decreases.

At such times, a treatment that fills the skin with moisture and elasticity from deep within

​that many people think of is skin boosters.

However, there are many types and the explanations can be complicated,

making it easy to get confused about which product is right for me.

Among them, the two most sought-after are

exactly JuveLook and Rejuran.


Today, let's compare the differences and characteristics of Rejuran and JuveLook

to find out which is more suitable in which case.





💧 Difference between Rejuran and JuveLook

JuveLook is a collagen booster

based on the ingredient PDLLA (Poly-DL-lactic acid).

Once it enters the skin, it induces self-collagen production

and shows the effect of gradually increasing elasticity and volume over time.

Rather than immediate changes, after 2 to 3 months

you will feel the skin slowly becoming firmer and denser.

However, if the injection site or hydration process is not done properly during the treatment,

💥small nodules may form, so


​it is important to choose a medical professional with rich experience.




On the other hand, Rejuran is a regenerative skin booster that utilizes the ingredient PN (PolyNucleotide).

It is a skin booster that activates skin cells and helps regeneration.


It is effective for improving internal dryness and skin texture
and is close to management that enhances the skin's natural recovery ability.

It is especially recommended for those who suffer from severe internal dryness or dullness.


However, Rejuran has a higher viscosity, which may cause pain during injection,

but these days, there are many cases where Rejuran HB products are used to reduce pain,

or anesthetic creams are used together.

💉It must be injected at exactly 1 to 2mm depth into the dermis,

so it is recommended to receive it from a medical professional with delicate skills.





💡 Which skin booster is right for me?

Both JuveLook and Rejuran

have a positive impact on the skin, but their directions are slightly different.

JuveLook is strong in improving structural problems like a sagging face with decreased elasticity and volume, or pores and scars.

If you want the volume to naturally increase over time,

JuveLook would be a better fit.



On the other hand, Rejuran is suitable for those with thin and sensitive skin

or those concerned about internal dryness and regeneration.

It helps to boost the skin's natural regenerative ability

and soften the texture and restore moisture.

👉 In other words, even if it is the same skin booster, the choice can vary depending on the current state of your skin
​and what kind of change you want.





🩵 To summarize


🫧JuveLook is a treatment that fills collagen with PDLLA ingredients, enhancing elasticity and volume,
🫧Rejuran is a treatment that regenerates the skin with PN ingredients and
makes it moist.

Ultimately, what is important is not the trend,

but knowing what your skin needs right now.

If you accurately diagnose your skin condition with a specialist

and choose the skin booster that is right for you,

you will be able to achieve more satisfactory results.





💬Difference between Rejuran and JuveLook Q&A

Q1. When will I see the effects of skin boosters?

Usually right after the treatment, the skin texture

feels slightly smoother and hydrated.

However, the significant improvement in elasticity

appears after 2 to 3 weeks,

and in the case of JuveLook, you can feel a more definite change

after about 2 months, which is the collagen production cycle.






Q2. How often should skin booster treatments be done?

It varies depending on skin condition, but

it is generally recommended to do it more than 3 times at intervals of 3 to 4 weeks.

Rejuran tends to be more regeneration-focused and often involves a series of 4 times followed by maintenance treatments,

and JuveLook may have reinforcement treatments every 6 months to 1 year after 2 to 3 times.






Q3. Is it okay to receive skin boosters every season?

Yes, treatments can be done regardless of the season.

However, in dry seasons with large temperature differences like winter,

the skin barrier gets weakened, so

it is better to choose a skin booster with significant moisturizing and regenerating effects.

In the summer, skin boosters like Rejuran, which help recover from UV damage, or calming skin boosters are suitable.




Consistent management is what makes the skin most beautiful, more than immediate changes.

I hope skin boosters can be the beginning of that,

and I encourage you that your skin becomes healthier every day.

I hope today’s article was helpful.

Kim Jang-ju.
