How to Use a Retinoid: A Simple Guide to ISOV Time Reset HD Serum
Share
Retinoids are some of the most effective ingredients you can add to a slow-aging skincare routine, but they can also be intimidating.
ISOV Time Reset HD Serum makes incorporating a retinoid into your routine fairly simple. You just need to know how often to use it, where it belongs in your routine, and when your skin is telling you to back off.
What Does Time Reset Do?
Time Reset HD Serum is a retinoid serum designed to support skin renewal and help improve visible signs of aging.
With consistent use, retinoids can help improve the appearance of fine lines, uneven texture, pigmentation, and overall skin quality while supporting collagen production.
This isn't a product you need to use every night to benefit from it. Consistency matters more than frequency.
Who Is It For?
Time Reset is a good addition if you're looking to address:
- Fine lines and visible signs of aging
- Uneven skin tone
- Rough or uneven texture
- Pigmentation
- Slower skin renewal
If your skin is currently irritated, overly sensitive, or your barrier is compromised, work on getting your skin healthy and comfortable before introducing a retinoid. Please note that some skin will never tolerate a retinoid, and that's okay.
Start Slowly
More isn't better with retinoids.
If you're new to Time Reset, begin with one or two nights per week. Once your skin is tolerating it comfortably, you can gradually increase how often you use it if needed.
You don't have to work your way up to nightly use. If your skin is doing well using Time Reset a few nights each week, that's perfectly fine.
How Much Should You Use?
You only need a small amount.
Apply a thin layer to the face rather than saturating the skin. Using more won't make the retinoid work faster—it simply increases your chances of irritation.
Avoid the delicate eye area unless you're using a product specifically formulated for it.
Where Does It Go in Your Routine?
Use Time Reset in your evening routine.
A simple routine looks like this:
- Cleanse
- Apply Time Reset HD Serum
- Apply moisturizer
If your skin tends to be sensitive, applying moisturizer before and after your retinoid can help make it easier for your skin to tolerate.
Be Careful With Other Active Ingredients
Your retinoid doesn't need competition.
On the nights you use Time Reset, I generally recommend keeping the rest of your routine simple. Avoid layering it with strong exfoliating acids or other potentially irritating active ingredients unless you've been specifically advised to use them together.
Those products can still have a place in your routine. They simply don't all need to be used on the same night.
If Your Skin Becomes Irritated
A little dryness can happen when introducing a retinoid, but persistent burning, significant flaking, redness, or sensitivity is a sign to back off.
Stop using Time Reset temporarily and simplify your routine. Focus on gentle cleansing, hydration, and barrier support until your skin feels comfortable again.
Once your skin has settled, you can reintroduce it at a lower frequency.
Sunscreen Is Non-Negotiable
If you're going to invest in a retinoid to improve visible signs of aging, protect that investment.
Wear a broad-spectrum sunscreen every morning and apply enough to adequately cover your face, neck, and other exposed skin.
Retinoids and sunscreen work toward the same bigger goal in different ways: helping you maintain healthier-looking skin for the long term.
How to Use Time Reset
Start with: 1–2 evenings per week
Amount: A thin layer, typically one pump
Apply: After cleansing and before moisturizer
Avoid that night: Strong exfoliants and unnecessary active ingredients
Morning: Always follow with sunscreen
Give your skin time to adjust. You don't need the most complicated routine or the highest possible frequency to get the benefits of a retinoid.
You just need a routine your skin tolerates well enough for you to stay consistent with it.
