Quick answer: How long an acne mark takes to fade depends on the color it left behind. Brown marks that sit in the epidermis are usually described as taking 6 to 12 months after the cause stops, while red marks vary more from person to person and can take anywhere from a few months to a few years. If the skin is indented or raised into a scar, consider seeing a dermatologist instead of setting a waiting period.
When a red tinge or a brown spot stays where a pimple has settled, most people start by looking for a new product. This guide helps adults sort the acne marks they have left into two kinds by color, and lays out, within the range of published literature, how to tell them from indented scars, what to wait on, and what to change now. It does not cover choosing scar procedures or prescription topicals.

What are acne marks? How are red marks, brown marks, and indented scars different?
An acne mark is a change in the color of the skin surface that stays after a pimple settles, and a scar is a change in the height of the skin. Marks differ in color depending on what was left behind. A mark that stays red is a flat red spot that forms when capillaries remain widened where inflammation has passed, and a mark that stays brown is an increase in pigment; how fast it fades depends on whether that pigment stayed in the epidermis or went down into the dermis (see AAD guidance on acne scar symptoms · StatPearls on pigment changes after inflammation). Indented scars come in ice pick, rolling, and boxcar shapes, and raised scars include hypertrophic scars and keloids. So even if you call a red mark an “acne scar,” it is more accurate to first check with your fingers whether there is any change in height.
| What to check | Red marks (redness after inflammation) | Brown marks (pigment left behind) | Indented or raised scars |
|---|---|---|---|
| What is left | Widened capillaries | Increased pigment | Tissue made with too little collagen (indented) or too much (raised) |
| Color you see | Pink to red | Light brown to dark brown | Same as the skin tone, or overlapping with red or brown |
| When you touch it | Flat | Flat | Indented, or firm and raised |
| Skin tone where it stands out more | Lighter skin tones | Darker skin tones | Keloids are more common in darker skin tones |
| Time until it fades | Varies widely by person (a few months to a few years) | 6 to 12 months if it stays in the epidermis | Does not fade the way color does — this is not something to wait out |
| What you can do at home | Keep your hands off it, do not add steps | Same as left, plus SPF 30 or higher sunscreen in the morning | Talk through the methods and their limits at a dermatology visit |
Sources: AAD, Acne scars: Signs and symptoms · AAD, Acne scars: Causes · AAD, How to fade dark spots in darker skin tones · StatPearls, Postinflammatory Hyperpigmentation (2024). The time frames are guidance for groups and do not guarantee a time frame for any one person.
For brown marks, guidance says that once you find and stop what darkened the skin, a mark a few shades darker than your natural skin color usually fades within 6 to 12 months (see AAD guidance on dark spots). This is general guidance on brown marks and is not a basis for applying the same time frame to red marks or scars. It is hard to tell pigment in the epidermis from pigment in a deeper layer at home, or to be sure of the time frame, so if nothing changes or the diagnosis is uncertain, have it checked at a dermatology visit.
Squeezing or picking at a pimple can raise the risk of inflammation and scarring, but you cannot say for certain that a particular mark will become a scar.
Even in the same place, a different color means a different waiting period.

When do red and brown acne marks fade?
How long a red mark takes to fade differs from person to person, is hard to set as a single figure, and can be long. How fast a brown mark fades depends on several factors, including skin color, the degree of inflammation, and sun exposure (see StatPearls on pigment changes after inflammation). The table below separates how far public guidance answers the question “about when?” from the conditions that make it take longer.
| Type of mark | Time frame in the guidance | Conditions that make it take longer | When to have it checked at a visit |
|---|---|---|---|
| Red marks | A few months to a few years, with wide variation by person | When the spot is squeezed or scratched and inflammation comes back | When new swollen, painful bumps appear, or when the height of the skin changes |
| Brown marks (epidermis) | Usually 6 to 12 months after the cause stops | When exposure to ultraviolet and visible light continues, in darker skin tones, and when the inflammation was severe | When it has not faded after 12 months |
| Brown marks (pigment down in the dermis) | Longer than in the epidermis, and cannot be told apart at home | Same as above | When nothing changes or the diagnosis is uncertain |

What three things can you change now when acne marks are left behind?
1. Apply sunscreen as the last step in the morning
In skin with brown marks, sun exposure makes the pigment darker and slows fading. Cutting down on sun exposure helps keep marks from getting darker (see AAD guidance on dark spots). A 2022 systematic review of 47 studies (1,853 people) on topical management of brown marks also found that almost every study recommended using sunscreen of SPF 30 or higher (see Tan et al., 2022).
| Item | Standard | Basis |
|---|---|---|
| SPF | SPF 30 or higher | Recommended by almost every study in a review of 47 studies (1,853 people) on topical management |
| Protection range | Broad-spectrum (UVA and UVB), and a water-resistant product outdoors | AAD guidance on dark spots |
| When to apply | The last step of your morning routine, even on days you do not go out | AAD guidance on dark spots |
| What to add | Shade and a hat | AAD guidance on dark spots |
| Note | Visible light can also darken brown marks, especially in darker skin tones | AAD guidance on dark spots |

Reapplication intervals and the amount per use are not given here because the sources for this guide do not provide figures.
2. Do not pick off scabs or squeeze marks
Squeezing, picking, or scratching makes inflammation larger and raises the risk that it leads to a scar. When too little collagen is made, the result is an indented scar, and when too much is made, a raised scar (see AAD guidance on acne scar causes). The same rule applies where a scab has formed: leave it alone and do not pick it off. Your part at the mark stage is to cut down how often your hands go to that spot.
3. Do not add more steps that touch your face
Layering new products over a spot with a mark makes it harder to sort out what suits your skin and what does not. Keep only cleansing, moisturizing, and sunscreen in the morning, and leave everything else as it is for a while. If there is something new to add, add one thing at a time with a few days in between.
The step that stays in your morning order for as long as marks remain.

When should you consider seeing a dermatologist?
If it is the height of the skin that has changed and not the color, this is not something to wait out. A 2016 systematic review that pooled 24 randomized controlled trials (789 adults) comparing acne scar procedures rated the quality of evidence for most comparisons as very low (see Abdel Hay et al., 2016). An indented scar is not something to wait on at home; it is something to talk through, methods and limits together, in the exam room. If any one of the following applies, consider seeing a dermatologist.
- The spot where the mark was is indented.
- The spot where the mark was is firm and raised.
- New bumps appear that are swollen, red, and painful when pressed.
- A brown mark in the epidermis has not faded after 12 months.
- The marks that remain weigh on your daily life and your mood.
Writing down when a mark first appeared makes it quicker to explain in the exam room.

FAQ
How long does it take for red acne marks to go away?
Red marks vary widely from person to person and can take anywhere from a few months to a few years, so no fixed time frame can be given. They last longer if the spot is squeezed or scratched and inflammation comes back. If new swollen, painful bumps appear or the height of the skin changes, have it checked at a dermatology visit.
Do acne marks fade on their own over time?
It depends on the color. Brown marks are described as usually fading within 6 to 12 months after the cause stops, but red marks vary more from person to person. Indented or raised scars do not fade the way color does, so have them checked at a dermatology visit.
How do you tell red acne marks from brown ones?
A red mark is widened capillaries left behind, and a brown mark is increased pigment left behind. Red marks stand out more in lighter skin tones, and brown marks are more common in darker skin tones.
Do you really need sunscreen if you have acne marks?
Especially if brown marks remain. Sun exposure makes pigment darker, and sunscreen helps reduce new marks and also helps the marks that remain fade. Use SPF 30 or higher as the standard.
What should you put on skin where a mark is left?
Keeping cleansing, moisturizing, and morning sunscreen is better than adding steps. If there is something new to add, add one thing at a time with a few days in between.
Do acne scars go away naturally?
Unlike marks where only color remains, scars where the skin is indented or raised are not something to wait on at home. Cleansing and moisturizing with cosmetics is not a way to deal with scars, so if the height of your skin has changed, consider seeing a dermatologist.
What causes acne scars?
When too little collagen is made, the result is an indented scar, and when too much is made, a raised scar. Squeezing, picking, or scratching makes inflammation larger and raises the risk that it leads to a scar.
Should you pick off a scab on a pimple?
Leave it as it is and do not pick it off. Squeezing, picking, or scratching makes inflammation larger and raises the risk that it leads to a scar. At the mark stage, cutting down how often your hands go to that spot comes first.
If a mark has not changed in over a year, should you see a dermatologist?
If a brown mark has not faded after 12 months, it is time to consider seeing a dermatologist. Whether the pigment stayed in the epidermis or sits in a deeper layer is hard to tell at home, so if nothing changes, have it checked at a visit.
Is a dermatology visit different for acne marks and acne scars?
Marks where only color remains and scars where the height has changed are checked in different ways and have different options. If the skin is indented or firm and raised, do not wait, and consider seeing a dermatologist if new swollen, painful bumps appear as well.
In one sentence
Sort the acne marks you have left by color to set how long to wait, keep up sunscreen in the morning and keep your hands off the spot, and consider seeing a dermatologist if the skin is indented or raised.
SKIN9HARI products we recommend for this concern
If, while marks remain, you are cutting the steps that touch your face down to cleansing, moisturizing, and morning sunscreen, and choosing within that one moisturizing step and one spot step used only where needed, SKIN9HARI recommends Revive Therapy N.F Cream and Centella Rescue Spot Ampoule. There are three reasons.
- The N.F Cream is a final-step moisturizing formula that lists 4 ceramides and 5 types of hyaluronic acid, which makes it a good single choice for the moisturizing slot in “keep only cleansing and moisturizing.”
- The Centella Rescue Spot Ampoule’s directions include the manufacturer’s wording “1 to 2 drops onto the spot where needed,” so you can use it only on the spots that bother you without adding a whole-face step.
- Both products are irritation patch-tested in finished-product patch tests (footnotes below the table). A patch test is safety data that looks at irritation reactions; it is not a test showing that marks, scars, or redness fade.
| Item | Revive Therapy N.F Cream | Centella Rescue Spot Ampoule |
|---|---|---|
| Size and price | 50 mL (1.69 fl oz) / $28.00 | 15 mL (0.5 fl oz) / $22.40 |
| Formula and labeled ingredients | Cream · 4 ceramides (NP, NS, EOP, AP) · 5 types of hyaluronic acid · panthenol · centella-family ingredients such as Centella asiatica extract listed · no fragrance or ethanol listed · capryloyl salicylic acid, gluconolactone, and lactic acid listed (amounts not disclosed) | Spot care ampoule · 27 ingredients listed (first ingredient ethanol · Centella asiatica extract · panthenol · bergamot oil and 5 listed fragrance components) · amounts of individual ingredients are not disclosed and so are not given |
| Test labeling | Irritation patch-tested — 24-hour occlusive patch, 30 adults (finished-product test) | Irritation patch-tested — primary skin irritation test (24-hour patch), 31 adults aged 20 to 60, average skin reaction score 0.00 (finished-product test) |
| Step in the routine | After the ampoule, the last step of the routine | After cleansing, on the spot where needed, or mixed into a toner or ampoule |
| Directions | After using toner and ampoule, dispense a suitable amount. Spread it gently over your face from the center outward. On areas where dryness bothers you, layer on a small extra amount to finish. | Spot care: after cleansing, drop 1 to 2 drops directly onto the spot where needed or spread it gently with your fingertips. Tip care: mix 3 to 4 drops of the Centella Rescue Spot Ampoule into the toner or ampoule you usually use. |
| Check before use (cautions) | If red spots, swelling, itching, or other abnormal reactions appear during or after use, stop using it and consult a dermatologist. Avoid using it on broken skin, and check the full ingredient list and expiration date on the latest container first. | Because it contains ethanol, you may feel a brief stinging sensation when applying it to troubled skin. If your skin is sensitive, test a small amount on an inconspicuous area first. This product is a cosmetic, not a medicine. |

How to use it for this concern. In the evening, spread the N.F Cream as the last step of your routine, after toner and ampoule. On days when only the spot with a mark bothers you, put 1 to 2 drops of the spot ampoule on that spot after cleansing, and if you already use a whole-face ampoule, mix 3 to 4 drops into it so you do not add a step. In the morning, apply sunscreen as the last step after moisturizing. Bring the two products in one at a time, and if ethanol has ever made your skin sting, start the spot ampoule with a small test, as its check-before-use wording says. Both products are cosmetics and are not a way to deal with indented or raised scars.
If anything under “When should you consider seeing a dermatologist?” above applies to you, seeing a dermatologist comes before products. Results may not be the same for every skin type. Product information is on the Revive Therapy N.F Cream product page and the Centella Rescue Spot Ampoule product page.
