Pepha Tight Serum Booster is a 0.5-ounce marine-derived firming serum booster formulated from Pullulan and marine algae to deliver an immediate film-forming lift and longer-term support for skin elasticity.

If you struggle with mild sagging, fine lines, or rapid moisture loss, this serum booster helps by forming a lightweight, tightening film on the skin's surface while acting as a humectant and barrier to reduce moisture loss. Add at a recommended concentration of 1-5% to your favorite serum, lotion, or cream for instant tightening effects and cumulative improvement with regular use.

  • Recommended usage: 1-5% concentration for serums and creams
  • 0.5-ounce blue glass dropper bottle to protect stability and light-sensitive actives
  • Contains Pullulan and marine algae, a collagen-like composition for improved elasticity
  • Immediate film-forming lift plus humectant action to support barrier function
  • Compatible with DIY serum boosters and ready-made formulas for customized anti-aging routines

Unlike heavier occlusive creams that mask slackness, this booster creates a breathable tightening film and can be blended into existing products to boost firming performance without reformulating. Compared to single-ingredient humectants, Pepha Tight combines barrier support with lift and collagen-like nourishment.

Paraben-free, vegan, and cruelty-free store packaging uses blue glass, and we recommend refrigeration after opening for potency. Found in select designer formulations and designed for clinical-strength DIY customization, this ingredient is recommended for targeted firming and elasticity support.

Questions & Answers

Ask a Question

  • As a DIY, how many drops of Pepha Tight do I add to a 1.5 oz bottle of eye cream I already have?

    For a 1% concentration, you would add 13.5 drops.
    For a 5% concentration, add 67 drops or 1/2 teaspoon plus 17 drops. 50 drops are equaled to 1/2 teaspoon. 

  • Can you explain better exactly how to make a 5% concentration? I just had neck and face lifts plus eyes and upper lip. What products will best help me prolong my results? Which serum should I mix this into. I’m almost 50. I guess right now I can pass for mid thirties? How do I know all marine algae’s are equal in their skin tightening. Which ones do you use and why?

    The Pepha Tight Serum Booster comes with an instructional brochure and chart. The chart shows recalculated amounts so that it is easy to find the correct amount to add. If you had a 1-ounce base, then you would add 45 drops of Pepha Tight. This is a great peptide to help firm the neck and jawline. You can add it to any one of our anti-aging serums for an added boost.

  • Hi. I use pepha tight in hyaluronic acid and apply to neck and face after getting my face wet with a bit of water. I use 1-2 drops for the whole area. Should I be using more to get more effect? Or is that enough? Also, it says to add 1-5%, but I noticed a product on here says 20% pepha tight. So I was wondering, if I want more of an effect, would I just add a larger percentage of pepha tight or just use more of the product I made. I did about a 3% add. I definitely notice a difference with it as is. Just wondering if I'm using enough to maximize it. Thanks!

    We recommend using a 1-5% concentration of Pepha Tight. Using a 5% concentration twice a day will give you the best results.

  • Hi, is this the full list of ingredients: INCI: Algae Extract (and) Pullulan? Or is it in a base with any other preservatives or anything else? Thanks

    All ingredients for the Serum Boosters are listed directly on the label and/or on the website listing. For Pepha Tight, the ingredient list is Algae (and) Pullulan. This version, however, is no longer being made as the manufacture discontinued that version. This month, the INCI will update to the new version. We never add any additional preservatives or ingredients to the Serum Boosters.

  • Can I use the Progeline, Relistase and Pepha Tight all at the same time? What percentage for each should I use if I want to use it twice daily for face and body. I'll be mixing all the ingredients with Cerave moisturizer lotion.

    Yes, you can use multipe serum boosters in your base including the Firming Serum Booster with Progeline, Relistase, and Pepha Tight.

    You can use any moisturizer as your base including Cerave. For the best results, use a combination of 2% Firming Serum Booster with Progeline, 4% Relistase, and 5% Pepha Tight.

    The manufactores recommendations for all boosters can be found directly on the product page.

    You can also check out more information about adding serum boosters here.

  • Can it be used with Matrixyl 3000, Matrixyl and/or copper peptides regenerating serum?

    Yes, you can use Pepha Tight with Matrixyl 3000 and Copper Peptide. They all can be added to the Rejuvenate Anti-aging Serum Base.

Frequently Asked Questions

What is Pepha Tight?
Pepha Tight is a marine-derived, film-forming ingredient made from pullulan and marine algae that provides an immediate lifting and firming effect on skin. It acts as a humectant and creates a breathable film on the surface, which temporarily tightens the appearance of fine lines and helps reduce transepidermal water loss. The product is offered as a .5 ounce blue glass dropper bottle and is intended for DIY or additive use at 1 to 5 percent of a final formula. Pepha Tight is popular as a serum booster because it both lifts on contact and supports improved elasticity with continued use. This makes it especially useful for ingredient-savvy users who want to customize serums and creams. Note that the instant lift is temporary and results improve with ongoing application; always patch test before adding to a full-face product and store the bottle refrigerated to preserve potency.
Is Pepha Tight good for mature skin with sagging or loss of firmness?
Yes. Pepha Tight is well suited to mature skin that shows loss of firmness because it delivers an immediate film-forming lift and supports skin elasticity over time. Specifically, its pullulan component forms a thin, tightening film that visibly smooths surface lines on first application, while marine algae-derived collagen-like material helps retain moisture and supports a more resilient skin barrier with continued use. It integrates easily into water-based serums, lotions, and creams at the recommended 1 to 5 percent range, so it is a practical choice for home formulations aimed at neck, jawline, and cheek firmness. Ideal users are educated, ingredient-focused women seeking clinical-strength feel without in-clinic procedures. Keep in mind results are cosmetic and temporary; for long-term structural change combine topical boosters with peptide actives and professional guidance.
How do I use Pepha Tight in my serum or cream and what concentration should I choose?
Use Pepha Tight as a booster at 1 to 5 percent of your final product and add it to water-based serums, lotions, or cream bases rather than oil-only formulas. The manufacturer recommends 1 to 5 percent because lower concentrations provide subtle lift and hydration while higher concentrations increase the immediate tightening and film effect. Practically this means measuring by weight or following a trusted DIY recipe; if you do not have a scale, start at a low percentage and increase gradually, patch testing after each change. After adding Pepha Tight, cap the blue glass bottle tightly and store the booster refrigerated to preserve activity. This approach benefits DIY formulators and users who want to enhance existing products; note that texture and feel of the finished product can change at higher concentrations and that patch testing is recommended for sensitivity.
Can Pepha Tight Serum Booster be safely combined with other anti-aging ingredients like Vitamin C or hyaluronic acid?
Yes, Pepha Tight Serum Booster is designed to be safely combined with popular anti-aging ingredients such as Vitamin C, hyaluronic acid, Matrixyl 3000, and Argireline. Its water-soluble formula allows you to add 1–5% directly into existing serums or creams without destabilizing most pH-balanced formulations. This flexibility lets you boost the skin-firming and instant lifting effects of multiple products, creating a custom regimen with professional clinical-grade results. This approach is ideal for ingredient-savvy women ages 35–65 seeking professional-strength benefits without fillers or parabens, making it perfect for advanced DIY skincare routines. However, always patch-test new mixtures, and avoid combining with highly acidic (pH below 4) products, which can reduce peptide efficacy. If you prefer a ready-made option, Skin Perfection also offers pre-formulated serums integrating Pepha Tight with proven actives for maximum results and convenience.
How does Pepha Tight Serum Booster compare to standard collagen serums for visible skin firming?
Pepha Tight Serum Booster delivers faster and more noticeable firming effects than most standard collagen serums, thanks to its potent 1-5% recommended concentration of marine-sourced Pullulan and algae extract—compounds clinically shown to provide an immediate skin-tightening film. Unlike typical collagen serums, which often use animal-derived or diluted ingredients, Skin Perfection’s Pepha Tight contains pure, plant-based actives that closely mimic your skin’s natural collagen structure for better absorption and enhanced elasticity. This formula is especially beneficial for women 35+ experiencing visible sagging or loss of firmness who want clinical-strength results without fillers, parabens, or a hefty price tag. While ready-made serums may offer convenience, customizing your skincare with Pepha Tight gives you full control over ingredient levels for professional-grade lifting power. For best results, consistent use in your favorite serum or cream amplifies both instant and long-term benefits.
