Red Light Therapy: What It Is, How It Works, and What It Can Do for Your Skin

by beautimate support in beautimate Blog | Skincare Tips, Tools & Beauty Secrets

Curious about red light therapy? Learn what it is, how it works, and how to safely use red and blue LED masks for skin benefits — backed by NASA research and dermatologists.

NASA Red Light Therapy ResearchNASA: Red LED light speeds healing — even in space.

What is Red Light Therapy?

Red Light Therapy (RLT) uses low-level wavelengths of red and near-infrared light to energize your skin cells. NASA scientists first tested it to help wounds heal in space. Today, people use it at home for anti-aging, acne, and skin recovery.

How Does Red Light Therapy Work?

RLT uses light to support cell energy and supports the skin's natural collagen process — which may lead to firmer, smoother skin over time. Blue light targets acne-causing bacteria, while red light may help calm the appearance of redness and support healing.

Derma Stamp Size Guide: 0.5mm vs 1.0mm vs 1.5mm (and How to Choose)

Microneedling guide How to choose the right derma stamp needle depth If you’ve looked at derma stamps and felt unsure which size to actually pick, that’s the part of this whole topic that gets glossed over the most. People talk about microneedling at home like the depth is a minor detail, but it’s honestly the single biggest factor in whether you’ll see results or end up irritated. This guide walks through every depth — 0.25 mm, 0.5 mm, 1.0 mm and 1.5 mm — in plain English. I’ll cover what each one actually does in the skin, what it’s best used for, how often to do it, and how much recovery to expect. By the end you’ll know exactly which depth fits your goal and how to step up safely over time. If you want the bigger-picture intro to microneedling at home first, start with our derma stamp vs. derma roller guide. An adjustable derma stamp lets you change the depth based on your goal — instead of buying a separate tool for every concern. Quick starting point: If you’re newer to microneedling, the Adjustable Derma Stamp is the easiest way in because it covers the full range. Pair it with the HYAH Serum for hydration after, or grab the Derma Stamp + HYAH Serum bundle if you want both together. What needle depth actually does Microneedling works by creating tiny, controlled channels in the skin. Your body reads those channels as something to repair, and during that repair process it lays down new collagen and elastin. That’s the whole mechanism — and the depth is what decides which layer of skin you’re actually working on. Different concerns live in different layers, which is why the depth matters so much. Surface glow and serum absorption live near the top. Fine lines and shallow texture sit a little deeper. Scars and stretch marks live deeper still. Match the depth to where the concern actually lives, and the results follow. A good rule of thumb: deeper is not better. The right depth is the one that matches your goal. Going deeper than you need just adds downtime and risk without adding results. Depth at a glance Before diving into each size, here’s a quick reference so you can see all four depths side by side. Depth Best for Typical rhythm Recovery 0.25 mm Serum absorption, glow, daily skin prep Two to four times a week Almost none 0.5 mm Fine lines, surface texture, scalp / hair About weekly 12–24 hours of mild pinkness 1.0 mm Deeper acne scars, stretch marks, stubborn texture Every 3–4 weeks 2–3 days of redness 1.5 mm Stretch marks and body scars (not face) Every 4–6 weeks 3–5 days of redness, possible pinpoint bleeding 0.25 mm — the “nano” depth for glow and absorption At 0.25 mm, the needles barely pass the outermost dead-cell layer of skin. There isn’t much real wounding happening, so this depth isn’t doing the heavy lifting on collagen — but it is excellent at one specific thing. That outer layer is built to keep things out of your skin, including most of your serums. A 0.25 mm stamp creates short-lived micro-channels that let actives sink in much more effectively for the first hour or so after stamping. It’s the same logic behind nano-needling in spas. Who it’s for: beginners testing how their skin tolerates microneedling, days when you’re using a higher-value serum and want maximum absorption, or anyone who wants a glow without committing to any real downtime. What it won’t do: build collagen, fade real scars, regrow hair, or smooth fine lines. For any of those, you have to go deeper. 0.5 mm — the most-used depth for almost every goal If you only ever use one depth, this is the one. 0.5 mm reaches into the upper layer of the dermis just enough to trigger collagen production, while staying safe enough for weekly use at home. It’s the most versatile depth in the whole range and the one I’d recommend for the majority of people. It works for fine lines, mild texture, early aging, surface acne scars, and — importantly — for the scalp when the goal is hair growth. Fine lines and early aging on the face Mild surface texture and hyperpigmentation Shallow acne scars Scalp microneedling for hair growth Body skin where you don’t need to go deeper How often: about once a week. Give your skin at least 5–7 days between sessions so the collagen process can actually do its work. Stamping more often than that doesn’t speed results, it just keeps your skin in a low-level irritation loop. Recovery: usually 12–24 hours of mild pinkness, similar to a light sunburn. Most people can go out the next morning with no visible signs. For hair growth specifically: 0.5 mm on the scalp, once a week, is the depth used in nearly every published microneedling-for-hair-loss study. If hair is your goal, this is the depth. For hair growth, 0.5 mm on the scalp is the depth used in nearly every published microneedling-for-hair-loss study. Aftercare matters a lot at this depth. Within the first hour, use a clean, fragrance-free hydrator — a hyaluronic acid serum is the easiest fit. For the next 24–72 hours, skip retinol, vitamin C, AHAs, BHAs and fragrance. If you want the full aftercare breakdown, read our guide on what to use after microneedling. 1.0 mm — for deeper scars and body work At 1.0 mm, the needles reach into the deeper part of the dermis, where rolling and boxcar acne scars actually live. That’s why this is the depth most people associate with “real” scar work. The trade-off is recovery time and a stricter approach. You can’t do this weekly, and you can’t treat it like a casual session. Best for Typical rhythm What recovery looks like Rolling and shallow boxcar acne scars Every 3–4 weeks 2–3 days of noticeable redness, possible pinpoint dots Deeper hyperpigmentation Every 3–4 weeks Mild flaking on day 3–4 as the surface turns over Stretch marks on the body Every 3–4 weeks Tightness and warmth for the first day Honest note: 1.0 mm is not a beginner depth on the face. If you’ve never microneedled before, spend at least 4–8 weeks at 0.5 mm before stepping up. Jumping straight to 1.0 mm is the most common reason people end up with hyperpigmentation, broken capillaries, or scabbing they weren’t expecting. Aftercare: same principles as 0.5 mm, but stricter. No actives for a full 72 hours, no direct sun, and no heavy sweating for 24 hours. Daily sunscreen for the next two weeks is non-negotiable. 1.5 mm — body only, advanced users only 1.5 mm reaches the deeper dermis where stretch marks and long-standing body scars sit. Facial skin is usually too thin for this depth in an at-home setting, so I’d keep 1.5 mm reserved for body areas where the skin is genuinely thicker. Stretch marks on stomach, hips, thighs, or breasts Older scars on the body Thicker skin areas where 1.0 mm hasn’t been enough How often: every 4–6 weeks, no more frequent than that. Recovery is long enough that pushing the rhythm faster only sets you up for prolonged inflammation. Recovery: 3–5 days of redness and tenderness. Pinpoint bleeding during the session is normal at this depth. The treated skin tends to feel hot and tight for the first 24 hours. Why I say “advanced users only”: jumping to 1.5 mm without prior microneedling experience increases the odds of post-inflammatory hyperpigmentation, irregular healing, or just a rough recovery week. Build up to it with 4–8 weeks of consistent 1.0 mm body sessions first. If you want to ease into body work at a safer depth, the Body Derma Roller (0.5 mm) covers larger surface areas faster than a stamp and is a sensible starting point for stretch mark routines. Why an adjustable stamp solves the “which one do I buy” problem Most derma stamps on the market are sold at one fixed depth. So if you start with 0.5 mm and later want to work on a deeper scar, you’re buying a second stamp. If you also want to nano-stamp on lighter skincare days, that’s a third. Suddenly you own a drawer of single-purpose tools. The Adjustable Derma Stamp was built exactly to fix this. One tool, dial-selectable from 0.25 mm to 3.0 mm, so the depth can match the session’s goal — without buying anything else. If you plan on microneedling long-term, an adjustable model usually pays for itself in the second or third stamp you don’t end up buying. A beginner-safe ramp-up If you’re new to derma stamping, the safest way to build up is gradual. This is the schedule I’d recommend. Weeks 1–4: 0.25 mm, two times a week. Build tolerance and learn the technique. Weeks 5–12: 0.5 mm, once a week. Now you’re in collagen-building territory. Keep aftercare clean — no retinol or acids for 48 hours after each session. Month 4+: 1.0 mm every 3–4 weeks, only if you have specific deeper scarring you want to target. Keep doing 0.5 mm weekly in between if you want. 1.5 mm: body only, and only after 8+ weeks of consistent 1.0 mm body sessions. The most common new-microneedler mistake is buying a 1.5 mm stamp first because “deeper sounds better.” It almost never is. Patience at the lower depths produces better long-term results than aggression at the higher ones. What to use right after stamping The first 24 hours after stamping is what gets called the “open window” — your skin is more permeable than usual. That’s an opportunity, but it’s also a risk if you reach for the wrong product. Apply right after Avoid for 24–72 hours Hyaluronic acid (calms, hydrates) Retinol and retinoids Peptide serums Vitamin C, especially L-ascorbic acid Centella or cica (anti-inflammatory) AHAs and BHAs Clean, fragrance-free moisturizer Fragrance, essential oils, brand-new actives Aftercare doesn’t need to be complicated. A calm, hydrating serum is usually the smartest move at any depth. For the full layering routine — including what order to use things in the days after — read our guide on what to apply after microneedling. FAQ Can I use a 1.5 mm derma stamp on my face? I wouldn’t recommend it. Facial skin is thinner than body skin, and 1.5 mm at home is the depth most associated with hyperpigmentation and prolonged downtime. Stay at 1.0 mm or below on the face. For deeper facial scarring, in-office RF microneedling is a better path than going deeper at home. Does deeper mean better? No, it just means different. The right depth is the one that matches the layer of skin where your concern actually lives. Going deeper than you need adds downtime and risk without adding results. Which depth is best for hair growth? 0.5 mm on the scalp, about once a week. That’s the depth used in nearly every published microneedling-for-hair-loss study. If you want the full hair protocol, see our derma stamp vs. derma roller guide. How long until I see results at each depth? 0.25 mm gives a same-day glow but no structural change. 0.5 mm tends to show texture and fine-line improvement around 4–6 weeks, with fuller results at 3 months. 1.0 mm scar improvement is usually visible around 6–8 weeks and continues for 4–6 months. 1.5 mm stretch mark work tends to show change at 8–12 weeks. Do I need to numb my skin? At 0.25 mm and 0.5 mm, almost never. At 1.0 mm, some people use a topical numbing cream — apply, wait 20 minutes, wipe off fully before stamping. For 1.5 mm on body, numbing is reasonable. Can one stamp handle multiple depths? Only if it’s adjustable. Fixed-depth stamps are single-depth tools. The Adjustable Derma Stamp covers 0.25 mm to 3.0 mm on a dial precisely so you can change the depth to fit the session’s goal. The short version If you’re picking your first depth, the answer for most people is 0.5 mm. It’s the most studied, most versatile, and safest weekly depth for face, scalp and most body areas. Step up to 1.0 mm only for specific deeper concerns, and only after you’ve built tolerance. If you want one tool that can grow with you from beginner nano-stamping all the way through deeper scar work, an adjustable stamp removes the entire “which one do I buy” problem. Once you’ve picked your depth, the next step is technique — for that, read our complete derma stamp tutorial.
