Post-Treatment Skincare: What to Use and What to Skip

What Your Skin Is Going Through

After any professional treatment, the surface of your skin looks and behaves differently. You might notice redness, sensitivity, tightness, or a temporary change in texture. This is normal. Your skin is in a state of heightened sensitivity, and its appearance can shift day to day in the first week.

The key thing to understand is that this window—the days immediately following a treatment—is when your skin is most responsive. What you apply during this time has an outsized impact on how your skin looks and feels as it settles.

The Post-Treatment Window

Think of the post-treatment period in three phases—which, not coincidentally, mirrors the approach behind the FACTORFIVE 7-Day Post-Treatment Kit, a protocol developed for use after professional procedures. Your esthetician may send you home with one after a peel or treatment. Some of the products in the kit are also available individually on the FACTORFIVE website and can be incorporated into your everyday routine—not just for post-treatment use.

If your provider has given you a specific protocol, follow that. The phases below are a general framework.

• Days 1–2

  Soothe
  Your skin has just been through something. This is not the moment for actives, exfoliants, or anything that adds stimulation. The goal is calm—gentle, supportive products that don't disrupt the surface while it stabilizes.
• Days 3–5

  Treat
  As sensitivity begins to settle, you can start reintroducing targeted support. Growth factor serums are well-suited to this phase—gentle enough for sensitized skin while actively supporting the appearance of skin through the transition.
• Days 5–7

  Restore
  By the end of the first week, your skin is ready to return to a more complete routine. Richer formulas, deeper support, and the ingredients that make up your normal regimen can come back in—thoughtfully, gradually, and with your provider's guidance.

Ingredients to Reach For

Not all ingredients are created equal in the post-treatment window. These are the categories your skin will thank you for reaching for.

• Growth Factors

  Protein signals that influence how skin looks at the surface. In the post-treatment window, they're particularly well-suited because they work gently—supporting the appearance of skin without the irritation risk that comes with more aggressive actives. More on this below.

• Gentle, Non-Foaming Cleansers

  Cleansing is non-negotiable, but the formula matters. Post-treatment skin doesn't need stripping. A gentle, non-foaming cleanser removes what needs to go without compromising the surface.

• Hydrating Ingredients

  Hyaluronic acid, glycerin, and similar humectants help support the appearance of plumpness and comfort. Post-treatment skin often looks and feels drier than usual—hydration helps.

• Barrier-Supporting Ingredients

  Ceramides, peptides, and nourishing oils help the surface look and feel more resilient. Think of them as reinforcement for skin that's in a more delicate state.

Ingredients to Avoid

This is the part most people struggle with—not because they're careless, but because they're reaching for their usual products out of habit. That said, every treatment is different, and your esthetician or provider may have specific guidance that differs from these general recommendations. Always follow their protocol first.

• Retinol & Retinoids

  Retinol is a powerful ingredient for the appearance of fine lines and texture—but not here, not now. Post-treatment skin is too sensitized for the cell turnover retinol drives. Save it for when your skin has fully settled, or until your provider gives you the green light.

• Exfoliating Acids

  AHAs, BHAs, and physical exfoliants are off the table. Your skin doesn't need more exfoliation—it needs support.

• High-Strength Vitamin C

  Low concentrations of vitamin C can be fine, but high-strength formulas—particularly L-ascorbic acid at a low pH—can be too stimulating for post-treatment skin and may cause irritation.

• Active-Heavy Formulas

  If a product has a long list of actives, this probably isn't its moment. Post-treatment is a time for targeted, simple formulas—not your most complex layering routine. When in doubt, ask your provider before reintroducing anything.

Why Growth Factors Belong in This Window

Of all the ingredients suited to the post-treatment period, growth factors stand out—and not just because we make them!

Growth factors are naturally occurring protein signals. In the context of post-treatment skin care, they're relevant because they're gentle enough for sensitized skin while still actively supporting the appearance of texture, tone, and overall skin quality. They don't exfoliate, they don't drive rapid cell turnover, and they don't add chemical stimulation.

The FACTORFIVE Post-Treatment Routine

The Gentle Gel Cleanser, Growth Factor Facial Mask, and Nourishing Silk are formulated with post-treatment skin in mind—gentle, supportive, and appropriate for skin in a more sensitive state. The Regenerative Serum and Anti-Aging Cream round out the restore phase as skin settles back into its normal state. All five are available individually on the FACTORFIVE website and work just as well as part of your everyday routine—not just after a procedure.

• Gentle Gel Cleanser Days 1–7

  The starting point for any post-treatment routine. A gentle, non-stripping formula that cleanses without compromising sensitized skin. Use morning and night throughout the post-treatment period—and every day after.

• Growth Factor Facial Mask Days 1–2 · Soothe

  A concentrated growth factor treatment formulated with post-treatment skin in mind. Apply on day one or two, when skin needs the most support, to visibly calm and comfort the appearance of skin after a procedure.

• Nourishing Silk Days 1–7 · Soothe & Treat

  A lightweight, fragrance-free, growth factor-infused formula formulated with post-treatment use in mind. Layers easily over serums and provides a gentle hydrating layer that supports the appearance of comfort and smoothness without heaviness. Transitions seamlessly into a daily moisturizer for ongoing use.

• Regenerative Serum Days 5–7 · Restore

  FACTORFIVE's hero growth factor serum. In the post-treatment protocol, it comes in during the restore phase—days five through seven—when skin is ready for more targeted support. As a daily serum, it's the active core of any growth factor routine.

• Anti-Aging Cream Days 5–7 · Restore

  A richer formula that rounds out the restore phase. Pairs with the Regenerative Serum to support the appearance of hydration, firmness, and overall skin quality as your routine returns to normal.

What We Wish More People Knew Before Leaving the Treatment Room

A few things that make a real difference in how your skin looks and feels after a procedure—and that don't always come up in the appointment. Keep in mind that every treatment is different, every protocol is different, and your provider's specific instructions always take priority.

• 1
  Listen to your esthetician or provider first

  The guidance in this blog is general. Your provider's post-treatment instructions are specific to you, your skin, and your procedure. When in doubt, call them. They are always your best resource.

• 2
  Start simple and add back gradually

  The instinct to layer your full routine immediately is understandable, but less is more in the first few days. Reintroduce products one at a time so you can identify anything that isn't agreeing with your skin.

• 3
  SPF is non-negotiable

  Post-treatment skin is more vulnerable to the effects of UV exposure. A mineral SPF every morning—even if you're indoors—is imperative during this period. Check with your provider on timing if you've had a more intensive procedure.

• 4
  Avoid heat

  Hot showers, saunas, and steam rooms can affect the appearance of post-treatment skin. Keep water lukewarm and give your skin time to settle before reintroducing heat.

• 5
  Patch test anything new

  If you're introducing a new product during the post-treatment window, patch test first. This isn't the time to experiment with unknowns.

• 6
  Be patient with the process

  Post-treatment skin goes through a visible transition. Day two might look different from day four. Give it the full week before drawing conclusions about how your skin is responding—and check in with your provider if anything doesn't feel right.

The Bottom Line

The post-treatment window is one of the most important—and most overlooked—parts of any professional skincare investment. What you apply in the days after a procedure directly influences how your skin looks as it settles.

Keep it simple. Follow your provider's guidance. Reach for gentle, supportive ingredients. Give your skin time. And when you're ready to layer back in your actives, growth factors are a good place to start—and to stay.
