This one you will feel working. The MEDITHERAPY Porethera Shot Exosome Spicule Serum uses exosome-coated spicules — microscopic needle-like particles derived from sea sponge — to create tiny channels in the skin surface so active ingredients reach deeper than they would from a standard serum. Behind them sits a genuinely active formula: niacinamide high on the list, plus azelaic acid and betaine salicylate. It is a weekly treatment, not a daily serum.
What It Does for Your Skin
- Refines the look of pores — clearing and resurfacing so pores appear tighter and less obvious.
- Smooths rough texture — spicules exfoliate physically at a microscopic scale.
- Works on tone and congestion — niacinamide, azelaic acid and a gentle BHA are all doing real work here.
- Improves ingredient delivery — the whole point of the spicule format is getting actives past the surface.
Who It Is For
Made for oily, congested skin with visible pores and rough texture, and for anyone who has plateaued with gentler products. Not for everyone: avoid it if your barrier is damaged, if skin is stinging, flaking or inflamed, or if you have active open blemishes or eczema. Very sensitive skin should patch test and approach cautiously.
Key Ingredients and Honest Notes
- Hydrolyzed sponge (spicules) — microscopic needle-like particles from sea sponge that create tiny channels in the skin surface. They cause a distinct prickling or tingling for several minutes, which is normal for this format.
- Niacinamide — third on the ingredient list, so present at a working level for tone and barrier support.
- Azelaic acid and betaine salicylate — a gentle acid pairing for congestion and the look of uneven tone.
- Exosome content — comes from lactobacillus extracellular vesicles and milk exosomes. In cosmetics, exosome describes a way of preparing an ingredient, not a medical treatment; this is a skincare formula rather than anything clinical.
- Contains milk exosomes — the formula is dairy-derived, so it is not vegan. Worth knowing if you avoid animal-derived ingredients.
An honest note on pores: this refines how pores look. Pore size is largely genetic, and no serum permanently shrinks it.
Texture and Sensation
A light serum with a gritty micro-texture you can feel as you apply it. Expect prickling or tingling for several minutes afterwards — that is the spicules working. Real stinging or burning is not normal; rinse off if that happens.
What to Expect
Skin usually feels smoother the morning after the first use. Refinement in pore appearance and texture builds over three to six weekly treatments. Mild redness or flaking can follow a session, so plan around important events. Because this resurfaces the skin and contains acids, daily sunscreen is essential while you are using it.
Where It Fits in Your Routine
An evening treatment, once or twice a week at most, after cleansing and before a calming moisturizer. Do not combine it with retinol or exfoliating acids on the same night. Explore more in Smooth & Pore-Refining Skin, Acne-Prone Skin and Korean Serums.

Frequently Asked Questions
What are spicules and how do they feel?
Spicules are microscopic needle-like particles that create tiny channels in the skin surface to help actives sink in. They feel prickly or tingly for several minutes after application, and that sensation is normal rather than a sign something is wrong. If it turns into real stinging or burning, rinse off and stop.
Who should avoid this serum?
Skip it if your barrier is currently damaged, if skin is stinging, flaking or inflamed, or if you have active open blemishes or eczema. Very sensitive skin should approach with real caution and patch test first. Spicules are a physical exfoliating format, so they ask more of your skin than a standard serum.
How often should I use it?
Once or twice a week at most, in the evening. This is a treatment rather than a daily serum, and overusing spicules is one of the quicker ways to irritate your skin. Give skin several days between uses and always follow with a calming moisturizer.
Will it make my pores smaller?
It refines how pores look rather than changing their size. Pore size is largely genetic, and nothing applied to skin permanently shrinks it. What this serum does is clear and smooth the surface so pores appear tighter and skin looks more refined — a visible improvement, not a structural one.
Can I use it with retinol or acids?
Not on the same night. Spicules, retinol and exfoliating acids all ask something of your barrier, and stacking them is how irritation starts. Use this on its own evening, keep the rest of that routine gentle, and return to your actives the following night.
