A personal calculator for microneedling depth,
cartridge selection and serum guidance,
based on your skin profile and my own research.
Slow travel, intentional self-care and honest reflection. I build things I wish existed: this app is one of them.
Short educational content on microneedling, skincare and self-care rituals. Product reviews, technique walkthroughs and my own processes.
This tool was built for personal use: it reflects how I plan and approach my own microneedling sessions. The goal was to organise the research, make the logic transparent and share it freely with anyone curious about doing the same.
Product suggestions link to a Seoul-based K-beauty supplier I personally use for skin boosters and microneedling serums. I am an affiliate: code JOSE gives you at least 15% off every order.
This is a personal reference tool, built from independent, non-professional research and publicly available scientific literature, not a substitute for a qualified dermatologist. I assume no liability for how this information is used; you're solely responsible for any decisions you make with it. Always consult a qualified dermatologist or skincare professional before performing any microneedling procedure.
This app is completely free. If it has been useful, there are two ways to support it.
Affects skin thickness, sebum production and ideal treatment parameters.
Facial hair affects how the cartridge glides and which zones can be treated.
Select all that apply. Your goals determine which serums and depths are recommended.
Select everything that applies - combinations are common. We'll tailor depths and products for your full picture.
These factors influence healing, photosensitivity, and how aggressively we can treat.
Fine-tune your session plan.
We'll calibrate depth to ensure healing is complete in time.
This shapes how deep we go and how much downtime to expect.
Helps calibrate collagen depth targeting and active ingredient selection.
Helps calibrate depth recommendations and flag post-inflammatory hyperpigmentation risk for deeper skin tones.
Olive, brown and deep skin tones carry a higher risk of post-inflammatory hyperpigmentation. If this applies to you, recommended depths will be capped at 0.5mm as a precaution.
This shapes cartridge pin count and speed recommendations. There is no right answer - honest input gives you the best plan.
Topical anaesthetic cream (e.g. EMLA) applied 30-45 min before. Reduces sensation but may slightly affect skin texture during needling.
Helps flag vascular guardrails. Skip if undecided.
