A Complete Guide to Skin Boosters in Seongsu-dong Dermatology: From Rejuran to Juvelook and Letygen, by Concern and Area

Skin Booster Complete Guide

Hello, this is Raon Dermatology in Seongdong-gu!

A simple yet effective way to improve the skin is skin boosters! They are effective at improving dryness and loss of elasticity that are difficult to resolve with everyday care alone. However, there are so many types available these days that many people have trouble choosing. So today, we’ll take a look at several kinds of skin boosters and summarize what advantages and features each one has :)

Skin Booster Complete Guide

Why is choosing the right skin booster important?

Accurately diagnosing your current skin condition and selecting the right ingredients is a key process that determines overall satisfaction. Depending on the ingredients contained in each product, the intended effects and mechanism of action of skin boosters are clearly different, so rather than applying them uniformly, a personalized choice must come first.

For example, if your skin is especially dry and lacks vitality, hyaluronic acid-based products are suitable. If enlarged pores and fine lines are your concern, it is better to use a booster specialized in regeneration and elasticity.

On the other hand, for sensitive skin that becomes red often, a regenerative booster that strengthens the skin barrier can provide practical help. If local hollowness or deep wrinkles are prominent, choosing a collagen booster that restores volume is the wise option! In this way, only by clearly setting priorities among hydration, skin regeneration, and volume formation according to the type of concern can you expect satisfying changes. If you simply choose a trending product, you may not see results.

<Skin boosters by concern type>

• Dryness / roughness: Hyaluronic acid-based

• Enlarged pores / fine lines: Regenerative, elasticity booster

• Sensitive skin: Regenerative skin booster

• Hollowness / deep wrinkles: Volume collagen booster

Why is choosing the right skin booster important?

Cocktail skin booster

The name “cocktail skin booster” may feel unfamiliar. It can be understood as a customized booster that combines hyaluronic acid and skin botox. The strong moisturizing power of hyaluronic acid helps relieve inner dryness, while a small amount of botulinum ingredient acts on the superficial layers of the skin to smooth fine wrinkles and tighten pores, creating a synergistic effect. This combination plays a major role in brightening skin tone while also forming a smoother texture.

For a more stable injection, using a multi-needle injector such as DermaShine is also worth noting. DermaShine lightly suctions and fixes the skin when injecting the medication, then delivers the set amount at the exact depth, which helps prevent medication loss and reduce pain. Because the active ingredients are administered at even intervals, the overall skin environment improves more consistently, and it also reduces possible post-injection bumpiness and bruising, lowering the burden of returning to daily life.

• Hyaluronic acid: strong moisturizing effect

• Skin botox: improves skin texture / pores / fine lines

• A synergistic booster that improves tone and texture together

Regenerative booster

If you want to enhance the skin’s natural recovery ability and restore a damaged environment, it is worth paying attention to the regenerative booster line, Re2O and Rejuran Healer. Re2O is a skin booster with hADM ingredients based on ECM that directly replenishes the various substances that make up the dermis. It helps skin regeneration and also strengthens overall density and thickness. It can be understood as a process of building basic skin resilience.

Rejuran Healer, which has long been loved, is also a representative regenerative booster that revives tired skin through PN ingredients extracted from salmon! By normalizing the skin cell regeneration cycle, it helps firm up the skin layer that has become thin due to aging and contributes to improving overall elasticity. Both Re2O and Rejuran Healer use ingredients with high biocompatibility, so they share the common advantages of having a low risk of foreign-body reactions and inducing natural changes.

Collagen booster

If you want to directly stimulate collagen, which naturally decreases over time, to restore facial dimension, Juvelook and Olidia Mayo can be effective options. Juvelook is a combination of high-molecular-weight PLA and hyaluronic acid, and its particles have a porous network structure inside, giving it excellent ability to promote self-collagen production. With an average fine particle size of 25–30 μm, it lowers the possibility of nodules when injected into the skin layer and creates natural volume. Thanks to the densely building elasticity, it can also positively help soften enlarged pores or depressed scar areas.

Meanwhile, Olidia Mayo is based on PLLA and has a porous spherical structure, which induces stable collagen synthesis within the tissue. With an average particle size of 40–63 μm, it has an advantage over Juvelook in creating slightly more distinct volume and improving deep wrinkles, and it is characterized by long-lasting practical maintenance. Because both products encourage the tissue itself to be filled without an artificial look, they are a satisfying alternative for those who want both aging prevention and improved dimensionality :) Depending on your skin thickness and the characteristics of the areas that need volume, it is necessary to choose one of the two boosters or use them together.

Wrinkle boosters for the eye area and mouth area

For wrinkles around the eyes or mouth, where the skin layer is thin and movement is frequent, it can be difficult to manage in detail with ordinary boosters alone, so specialized products such as Letygen should be considered. Letygen is a treatment that directly supplements sterilized pure collagen, and it plays an excellent role in improving tissue cohesion and immediately reinforcing elasticity. Its particles are very fine and soft, so they spread evenly without clumping even in areas with dense fine lines, providing practical firmness to the under-eye area or the skin around the mouth that has loosened due to aging.

In particular, because Letygen uses pure collagen similar to the skin’s own components, it has excellent stability after injection and can be applied to sensitive areas without 부담. For those worried about fine lines around the eyes or reduced elasticity around the mouth, using this kind of targeted booster can be a much more efficient approach. The various skin boosters we have looked at so far each have different ingredients and purposes. Therefore, rather than simply following trends, please make the decision that best fits your skin condition through consultation with a dermatologist :)

• Direct injection of sterilized pure collagen

• Sterilized collagen ingredient / relief of fine lines

• Immediate elasticity improvement / improvement of wrinkles around the eyes and mouth
