Your first line of action in treating acne scars? Nice and straightforward over-the-counter products. First things first, though: make sure that your acne is actually laid to rest. 'The most important thing is to know that your acne is under control, before starting any treatments,' says Dr Kluk.
'Otherwise, you'll get locked in a vicious cycle of trying to treat the effects of something that's still going on, which is disheartening.'
Next, head to the shops.
'Wearing sunscreen on a daily basis will help prevent UV from worsening your post inflammatory hyperpigmentation,' says Dr Bunting.
'A vitamin C product is good for applying topically, as it regulates pigmentation,' says Dr Kluk.
'While retinol can help to boost your collagen, if you have indented scars.'
If you head to your GP, you can also see about getting prescribed a stronger retinoid product, for the same reason. ('There is some evidence that prescription retinoids like tretinoin and tazarotene help our natural repair processes along – 35% of scars resolve by themselves over the course of three years, and topical retinoids can potentially reduce this timeframe,' adds Dr Bunting.)
Glycolic acid based products and peels can also help by exfoliating and minimising the depth of the scar, helping stimulate collagen and elastin – as well as reducing any discolouration.'" data-reactid="67">'Exfoliators won’t get rid of scars, but can help acne-prone skin by helping to resurface the complexion, preventing pores from clogging and fading pigmentation marks,' adds Mr McGeorge. 'Glycolic acid based products and peels can also help by exfoliating and minimising the depth of the scar, helping stimulate collagen and elastin – as well as reducing any discolouration.'
Cosmetic acne treatment
Quick note. Because a cosmetic procedure for acne scars is seen as non-essential by the NHS, you'll probably have to shell out for the below, unless you can prove that the scars are causing you significant psychological distress. For context, in the 12 months after being told that they have acne by a doctor, a person's risk for a depression diagnosis spikes by over 60%, according to a 2018 paper published in the The British Journal of Dermatology.
Prices will vary according to where you are in the country and the grade of dermatologist that you visit, so scope out clinics in your area and go from there.
Acne scar treatment: surgical removal
'If you have small, indented scars, they can be removed surgically,' says Dr Kluk. 'You don't need to treat your entire face – instead, a dermatologist can use a tool to puncture the skin surrounding the scar and then stitch the skin back together.'
Acne scar treatment: microneedling
This is great for scars over a bigger surface area. Microneedling is sometimes used as an aesthetic procedure, to stimulate collagen production for anti-ageing, but is often used in scar treatment, too. 'It works by inflicting a controlled injury to the skin,' explains Dr Kluk. 'Needles pierce the dermis where collagen is made, so that the cells increase their collagen production. This can improve the skin texture.'
Acne scar treatment: laser surgery
This is the same idea as microneedling – causing deliberate injury to the skin so that it produces extra collagen – but using a controlled laser beam, instead. You probably won't have any anaesthetic, but don't worry – you'll just feel a slightly warm tingle, rather than a harsh zap.
laser treatment – ablative laser treatment, where lasers are used to remove a small patch of skin around the scar to produce a new, smooth-looking area of skin, and non-ablative laser treatment, where lasers are used to stimulate the growth of new collagen which helps to repair some of the damage caused by scarring, and improves the appearance,' explains Mr McGeorge." data-reactid="77">'There are two types of laser treatment – ablative laser treatment, where lasers are used to remove a small patch of skin around the scar to produce a new, smooth-looking area of skin, and non-ablative laser treatment, where lasers are used to stimulate the growth of new collagen which helps to repair some of the damage caused by scarring, and improves the appearance,' explains Mr McGeorge.
Time frame-wise, you'l probably need between four to eight sessions, with a couple of weeks inbetween each one.
Acne scar treatment: cortisone injections
If your scars are raised and bumpy, than a type of steroid, cortisone, could be injected directly into the affected area, in order to flatten the area down. This will take a course of injections. 'You might four to six treatments over the course of six to eight weeks,' says Dr Kluk.
Acne scar treatment: TCA peels
'If you have ice pick scars, TCA peels can be effective,' says Dr Kluk. 'This is a type of acid peel, which gets deep into the skin to encourage cell regrowth, for smoother skin.' She notes that there is a risk in doing this sort of peel over your entire face, as you can face a) a lot of recovery time and b) you can make pigmentation worse.
'But if you do it targeted on the scars, in little areas, you can cause a burn and stimulate new tissue to fill the gap.'
Acne scar treatment: subcision
This is for really stuck down, deep scars. 'This involves sticking a needle under the skin, and breaking up the scar tissue. The release of the scar tissue – and the new collagen created – can help to smooth out the surface of the skin,' explains Dr Kluk.
