The world of DIY beauty can feel overwhelming at first. There are dozens of treatments, unfamiliar terminology, and a wide range of opinions on what works and what doesn’t.
This guide is designed to simplify that landscape. It organizes common DIY treatments into three levels – beginner, intermediate, and advanced – based on technique, risk, and the level of precision required.
The goal is not to tell you what to do, but to help you understand what each category actually involves.
Once you understand the mechanism behind a treatment, it becomes much easier to decide whether it belongs in your routine.
Beginner Level Treatments
Beauty Devices
At-home beauty devices use technologies like radio frequency (RF), microcurrent, IPL/DPL, cavitation, or laser to improve skin quality over time.
These devices work through heat, light, electrical stimulation, or mechanical energy to support collagen production, improve tone, and enhance overall skin appearance. They are designed for consistent, long-term use rather than dramatic one-time results.

Cosmetic Microneedling (≤ 0.5 mm)
Cosmetic microneedling uses very shallow needle depths to create microchannels in the skin.
At this depth, the primary benefit is enhanced product absorption, along with mild stimulation of skin renewal. It is commonly paired with sterile skin boosters such as PDRN, peptides, or exosomes to improve hydration, texture, and glow.

Microneedling
Subcutaneous (SubQ) Injections
Subcutaneous injections deliver substances into the fat layer beneath the skin, typically in the abdomen, thighs, or upper arm.
This method is commonly used for peptides, vitamins, and metabolic therapies, allowing for gradual absorption into the bloodstream. While systemic, these treatments can indirectly support skin health and overall regeneration.
Chemical Peels (Superficial / Buffered)
Superficial chemical peels use mild or buffered acids to gently exfoliate the outermost layer of the skin.
These peels are typically used to improve brightness, texture, and mild pigmentation with minimal downtime. Many Korean formulations are designed to be self-neutralizing or buffered, making them more forgiving and suitable for regular use.
Intermediate Level Treatments
Medical Microneedling (> 0.5 mm)
Medical microneedling uses deeper needle penetration to stimulate collagen remodeling within the dermis.
It is used to address concerns such as wrinkles, skin laxity, and scarring. Compared to cosmetic microneedling, it creates a stronger wound-healing response and requires greater spacing between sessions, careful technique, and appropriate post-treatment support.

Mesotherapy Injections
Mesotherapy involves injecting small amounts of sterile products into the superficial to mid-dermis.
These treatments are used for hydration, skin quality improvement, pigmentation, and hair support. Techniques vary, including micro-papules, nappage, and structured approaches such as BAP (Bio-Active Points).

Meso & BAP
Biostimulatory Injectables (PN, PDRN, Collagen, hADM)
Biostimulatory injectables are designed to improve skin quality by stimulating repair and regeneration, rather than adding volume or simply hydrating the skin.
These products may include polynucleotides (PN), polydeoxyribonucleotides (PDRN), recombinant human collagen, human acellular dermal matrix (hADM), or hybrid formulations that combine regenerative ingredients with hyaluronic acid or peptides. They are used to improve texture, elasticity, and overall skin health over time.
Some treatments in this category also include multi-weight or hybrid hyaluronic acid formulations (such as Profhilo-style products), which primarily improve hydration and tissue quality but can have mild biostimulatory effects depending on formulation and placement.
While often delivered using mesotherapy techniques such as micro-papules or BAP, they represent a distinct category due to their mechanism of action and cumulative effects. Results develop gradually with repeated treatments.
Fat Dissolver Injections
Fat dissolvers use compounds such as deoxycholic acid or phosphatidylcholine to break down localized fat deposits.
They are typically used in areas like the submental region (under the chin) or small body areas (abdomen, love handles, upper arms). Results occur gradually as the body metabolizes the disrupted fat cells.

Fat Dissolvers
PDO Threads (Smooth Threads)
Smooth PDO threads are dissolvable sutures placed under the skin to stimulate collagen production.
They provide subtle firming and skin quality improvement over time, rather than dramatic lifting. These are often used as an entry point into thread-based treatments.
Botulinum Toxin (“Tox”)
Botulinum toxin injections temporarily relax targeted muscles to reduce dynamic wrinkles caused by facial movement.
Common treatment areas include the forehead, glabella, and crow’s feet. Results are temporary and require maintenance.
Intramuscular (IM) Injections
Intramuscular injections deliver substances directly into muscle tissue, typically in the glute or deltoid.
This route allows for faster systemic absorption and is often used for vitamins, amino acid blends, or other supportive therapies.
Chemical Peels (Medium Depth)
Medium-depth chemical peels use stronger acid formulations, such as TCA or Jessner-based blends, to penetrate deeper into the skin.
These treatments are used to target more significant concerns such as pigmentation, sun damage, and fine lines. They require careful application, proper skin preparation, and an understanding of layering and endpoints to achieve consistent results.
Advanced Level Treatments
Advanced Threads (Cog, Screw, Barbed)
These threads include structural elements (cogs, cones, or twists) that anchor into tissue to provide lifting in addition to collagen stimulation.
They are used for more significant repositioning of tissue and require precise placement and planning.
Dermal Fillers
Dermal fillers restore volume, enhance contours, and soften static wrinkles.
Most commonly made from hyaluronic acid, they can also include biostimulatory materials. Placement technique and anatomical knowledge are critical to achieving natural results.
Collagen Stimulators (PLLA, PCL, PDLLA)
Collagen stimulators trigger the body to produce new collagen over time rather than providing immediate volume.
Examples include poly-L-lactic acid (PLLA), polycaprolactone (PCL), and PDLLA-based products. Results develop gradually and can last significantly longer than traditional fillers.
These treatments are considered advanced because they require precise placement, appropriate dilution, and controlled distribution. Many protocols involve cannula use rather than needles, and improper technique can lead to uneven results, nodules, or prolonged inflammatory responses. Unlike hyaluronic acid fillers, these materials are not easily reversible.
Not every treatment in this guide is necessary, and most people will never need all of them. The goal is simply to understand what each one does, so you can choose intentionally as your routine evolves.
Progress doesn’t have to mean moving into more advanced categories. In many cases, it’s more effective to stay within a level you understand and expand outward – applying the same techniques from face to neck, hands, and body as your confidence and goals grow. Each area has its own differences and challenges, which creates opportunities to continue learning without increasing overall risk.
