Suitable For

  • All Skin Types
  • All Ages
  • Normal to Oily Skin

Targets

  • Uneven Skin Tone
  • Blemishes & Breakouts
  • Skin Radiance

Dr Sebagh’s award-winning resurfacing mask, the closest thing to a professional facial you can do at home. Lactic acid dissolves dead skin cells and accelerates cell turnover, while azelaic acid targets acne-causing bacteria, decongests pores, reduces inflammation and fades post-inflammatory pigmentation. Palmitoyl Pentapeptide-4 stimulates collagen synthesis at the same time, so it exfoliates and supports skin structure in one step. Skin is visibly smoother, clearer and more radiant after a single 3 to 5 minute application. Not suitable for sensitive skin.

Benefits

  • Rapidly resurfaces by dissolving dead skin cell build-up and impurities.
  • Decongests pores and reduces breakouts and comedones.
  • Visibly smooths skin texture and refines surface irregularities.
  • Brightens uneven tone and helps reduce pigmentation, including post-inflammatory hyperpigmentation caused by breakouts.
  • Calms inflammation while supporting skin clarity and balance.
  • Stimulates collagen and elastin to improve firmness and elasticity.
  • Works in just 3 to 5 minutes, ideal before an event.

Application

  • Use once or twice a week. Massage into clean, dry skin, avoiding the eye area.
  • Leave for 3 to 5 minutes, then rinse off thoroughly with warm water. Do not leave on for longer than 5 minutes.
  • A tingling or stinging sensation is normal. If it becomes uncomfortable, rinse off straight away.
  • For a two-step skin prep, follow with Skin Perfecting Mask.
  • Expert tip: mix with Pure Vitamin C Powder Cream in your palm before applying, to help reduce pigmentation.
  • Not suitable for sensitive skin or skin prone to eczema; try Deep Exfoliating Mask Sensitive Skin instead. Patch test behind the ear before first use.
  • The AHA in this mask may increase sun sensitivity. Use a high SPF, wear protective clothing and limit sun exposure while using the mask and for a week afterwards.

Key Ingredients and Actives

Lactic Acid

An alpha hydroxy acid (AHA) selected for its exfoliating benefits, removing dead skin cells, impurities and waste products from the skin. It also increases skin hydration and cell turnover, leaving the surface refined and the complexion radiant.

Azelaic Acid

A multi-tasking acid proven to work against acne-causing bacteria (P. acnes). It regulates cell proliferation, reducing the occurrence of comedones, has an anti-inflammatory effect, and shows skin-lightening properties that are particularly effective for post-inflammatory hyperpigmentation (PIH).

Silanediol Salicylate

A silicium derivative that helps the skin defend itself against environmental aggressors. Its antioxidant properties help limit free radical damage and glycation, while supporting collagen.

Palmitoyl Pentapeptide-4

A peptide made by linking five amino acids that stimulates collagen and elastin, developing fibronectin and glycosaminoglycans such as hyaluronic acid. Proven to reduce the appearance of both deep and medium wrinkles.

FAQs

What does Deep Exfoliating Mask do?

It exfoliates dead skin cells and impurities with lactic and azelaic acid, leaving skin instantly brighter, smoother and more polished in 3 to 5 minutes. A pentapeptide and a silicium derivative add collagen-supporting and antioxidant benefits.

How often should I use Deep Exfoliating Mask?

Once or twice a week. If you are new to acid exfoliation, start once a week and build up gradually.

How long should I leave it on?

3 to 5 minutes, then rinse off thoroughly with warm water. Do not leave it on for longer than 5 minutes.

Is it normal for it to tingle?

Yes, a tingling or stinging sensation is normal while the acids work. If it becomes uncomfortable, rinse it off straight away.

Is Deep Exfoliating Mask suitable for acne or breakout-prone skin?

Yes. Azelaic acid is a clinically recognised active that targets acne-causing bacteria, regulates cell turnover and reduces the inflammation that leads to breakouts. With continued weekly use, pores appear more refined, congestion clears and breakouts become less frequent. It also helps fade post-inflammatory pigmentation left behind after blemishes heal.

Will it help with pigmentation and dark marks?

Yes. The combination of lactic acid and azelaic acid makes this one of the most effective at-home treatments for uneven skin tone and post-inflammatory hyperpigmentation. Lactic acid accelerates the shedding of pigmented surface cells, while azelaic acid targets excess melanin production at source. For extra help, Dr Sebagh recommends mixing it with Pure Vitamin C Powder Cream in your palm before applying.

Can I use it if I have sensitive skin?

No. It is not suitable for sensitive skin or skin prone to eczema. Choose Deep Exfoliating Mask Sensitive Skin, a gentler formulation.

Can I use it before an event?

Yes. It leaves skin looking smoother, brighter and more polished in 3 to 5 minutes, which makes it a favourite pre-party treatment. Use it on the day or the day before.

Do I need to wear SPF after using it?

Yes. The AHA in the mask may increase the skin’s sensitivity to the sun. Use a high SPF, wear protective clothing and limit sun exposure while using the mask and for a week afterwards.

Will Deep Exfoliating Mask dry out my skin?

No. Unlike many AHA treatments that leave skin feeling tight or stripped, it is formulated to maintain comfort and hydration while it exfoliates, leaving skin soft, smooth and balanced.

What makes Deep Exfoliating Mask different from other exfoliating masks?

Most exfoliating masks use a single acid to resurface the skin. Deep Exfoliating Mask works on four pathways: surface renewal with lactic acid, pore clarifying and anti-inflammatory action with azelaic acid, environmental defence with Silanediol Salicylate, and collagen support with a peptide. It is the only exfoliating mask in its category that supports the skin’s collagen matrix while it resurfaces, making it a genuine treatment rather than a simple scrub.

What can I use with Deep Exfoliating Mask?

Follow with Skin Perfecting Mask for a two-step skin prep, then Serum Repair to replenish hydration. Mix with Pure Vitamin C Powder Cream for a brightening boost.

A Game-Changer for Radiant Skin!

I absolutely love the Dr. Sebagh Deep Exfoliating Mask! The vibrant orange color makes it feel like a true Vitamin C powerhouse, and the results speak for themselves. After just one use, my skin felt incredibly smooth, fresh, and glowing.
The lactic and azelaic acids work wonders—gently exfoliating dead skin cells, improving texture, and brightening my complexion. I especially love how it helps with uneven skin tone and breakouts while boosting cell turnover. It’s the perfect pre-event skincare ritual for a radiant, polished look!
A slight tingle lets you know it’s working, but it’s totally worth it. I was provided this mask as a gifted product and will definitely keep buying! If you want glowy, refined, and smoother skin, this is a must-try!

Good product, but overpriced

Very quick and easy to use before a night out. I would purchase again if I had the money, however I believe the ordinary AHA peel does the same thing for a fraction of the cost.

Nice! Leaves skin smooth!

Not too strong a scent, left my skin very soft. Probably not suited for sensitive skin. Good product, would recommend but the price would likely exclude a lot of people.
