Doesn’t take all the fan off. Leaves blotchy
Doesn’t get the tan off all the way and I’ve used it 4 times now. It makes the tan blotchy and uneven (yes I know that’s what happens when the tan is going away but like I said I’ve used it 4 times and it hasn’t made much difference. A regular exfoliant works better) I used the same brand tanner as well so not sure why it’s not working. Bummed tho!

What a find!
Color: PDRN 25%
Good stuff! My skin healed ULTRA fast with this!! I can really tell it is good stuff! Plus, it has that “bio” smell that means it’s real. The formula is a little oily as opposed to watery. Just FYI I think serum slightly thicker is better.

Oopsy Daisy, bad for not reading directions!
Color: PDRN 25%
Oops 😬, I forgot to mix this PDRN serum with my hyaluronic serum before applying on my skin. Instead I have been applying it directly on my face 2x daily. I have noticed major improvement on my skin. My skin is dewy, bright, and flawless. Fortunately, I did not experience any skin reactions the undiluted product. I will come back and stock up on these bottles to mix with hyaluronic serum for microneedling.

The Skin Regenerator Your Routine Is Missing
Color: PDRN 25%
If you've been dealing with dull, dehydrated skin or feel like your usual creams just aren't cutting it anymore, the Salmon DNA PDRN 250,000 ppm Concentrate might be the missing piece. I started using this booster three months ago, and it has genuinely transformed the texture and bounce of my skin. What problem does this solve? As we age or expose our skin to environmental stress, our natural cell regeneration slows down, leading to dullness, loss of firmness, fine lines, and a damaged moisture barrier. This PDRN concentrate essentially acts as a cellular "wake-up call." Salmon DNA shares a remarkably high biocompatibility with human skin, helping to repair DNA damage, reignite collagen production, and speed up the skin's natural healing process. Features & Benefits · Regenerative Power: Packed with 25% (250,000 ppm) PDRN (Polydeoxyribonucleotide) to repair and rejuvenate. · Wrinkle & Texture Refinement: Helps improve elasticity and reduce fine lines for smoother, more resilient skin. · Hydration & Barrier Support: Formulated with Sodium DNA and Panthenol to deeply replenish moisture and soothe sensitivity. · Booster Format: A versatile concentrate you mix with your moisturizer or serum to amplify your entire routine. · Enhanced Complex: Includes EGF (Epidermal Growth Factor) and Peptides for added collagen support. Pros · ✅ High concentration of active ingredients for noticeable results. · ✅ Excellent for post-procedure skin (non-irritating after microneedling). · ✅ Improves overall skin health, not just surface appearance. · ✅ Suitable for all skin types looking for anti-aging or hydration. Cons · ❌ Texture can be sticky – it leaves a slight residue on your fingers and face that takes a few minutes to absorb. · ❌ Requires consistency – results are not instantaneous and need regular use to build. · ❌ The concept of "salmon DNA" might feel unusual to some, though it's highly effective and dermatologist-backed. Final Verdict This isn't a quick-fix product, but if you stick with it, the reward is skin that looks plumper, healthier, and more resilient. It’s like sending your skin into a repair shop. Best for anyone who has hit a plateau with their current anti-aging routine or who wants to actively strengthen their skin's foundation.
