Until the age of 30, people suffer from acne. After that, the problem of acne scars (scars) continues

Many people in their teens suffer from puberty acne due to sebum secretion, and many people in their 20s and mid-30s suffer from adult acne due to hormonal imbalance. By the time you reach your 40s, you may only get one or two pimples once in a while. However, some people may still be suffering from acne scars even after reaching an age where acne is no longer possible.

Acne scars (scratches) are more likely to remain the longer acne inflammation lasts, so it is important to treat acne early in the first place in order to avoid leaving acne scars (scratches).

Acne scars can be categorized into three main types.

Causes and remedies for reddish acne scars

When the dermis of the skin is damaged by inflammation caused by acne or popping the pimple, the capillaries in the dermis bleed. Areas of the skin that have been soaked with blood become red.

Also, when the epidermis and dermis are damaged, the affected areas become thinner, making it easier to see through the underlying blood vessels. In addition, damaged capillaries tend to dilate, making the area appear red.

Redness usually subsides naturally in about 3 to 6 months, but it may last longer.

For self-care, it is recommended to use cosmetics containing astaxanthin, which has an anti-inflammatory effect, as it will improve faster.

To reduce the redness, apply a prescription zinc ointment that has anti-inflammatory properties. It has a soothing effect even when there is no inflammation on the surface of the skin.

You don’t usually have redness, but after taking a bath or drinking alcohol, do you have scars or acne scars (marks) that appear red?

After taking a bath or drinking alcohol, the blood flow improves and the capillaries dilate, making the face and body red. Once a scar has been formed, the capillaries themselves tend to dilate, so the redness of the acne scars that were once formed may be noticeable. It will also heal with time.

In addition to acne scars (scars), there is also a skin disease called “rosacea”, commonly known as “red face”, that occurs in areas where pimples are likely to occur. The underlying cause of rosacea is unknown, but excess sebum production is always involved. It is often seen mainly in middle-aged and elderly people, and there are symptoms such as redness due to opening of blood vessels and inflammation of pores and lumps. It is treated with a combination of ointment, oral medicine, laser treatment, etc.

Causes and remedies for brownish pigmented acne scars

When the skin becomes inflamed, melanin is produced in the scarred area, resulting in pigmentation. If it’s brown instead of red, it’s post-inflammatory hyperpigmentation. It will disappear in a few months to a year, but it may remain depending on the skin type and the intensity of the inflammation.

In the case of self-care, whitening care should be taken with cosmetics that suppress the overproduction of melanin and help the smooth discharge of melanin without accumulating in the skin. It is a good idea to use cosmetics containing vitamin C derivatives, hydroquinone, tranexamic acid, and other whitening ingredients.

Causes and remedies for scarred acne scars

Scars are so-called scars, and there are hypertrophic scars and depressed scars. Depressed scars are commonly called craters. Depending on the part, the scar after the acne heals may be depressed or raised.

If inflammation occurs repeatedly in one pore, it may damage the dermis around the pore and cause scarring after the acne has healed.

The shape of the crater differs depending on the part. On the face line where the bone is just below, it becomes hard and lumpy and it is easy to swell. On the other hand, cheeks and temples tend to have craters that look like holes.

Some people may also develop lumps on their cheeks and chin. Inflammation spreads from the acne-prone area to the surrounding normal skin, causing excessive production of collagen (collagen fibers), red swelling, and keloid formation. It is often painful and itchy.

Cratered or keloid skin cannot be healed by self-care and must be treated at a hospital. It is recommended to start treatment early so as not to suffer from acne scars (scars), and to apply astaxanthin, which has various effects in addition to anti-inflammatory effects.

How to treat acne scars, scar spots and redness?

Treatment at a beauty clinic

To be honest, it is quite a struggle to erase acne scars (scars) that remain clearly even in my 50s with home care. It would be quicker to seek treatment at a cosmetic dermatology or plastic surgery clinic.

Peeling, topical retinoic acid, and lasers for acne scars (scars) are now on the menu. There are also treatments to improve redness using a laser that works on the cause of redness, oxygenated hemoglobin, and laser treatments to make craters shallower. Treatment methods vary depending on the condition of the acne scars.

For example, at a clinic in Tokyo, one treatment for both cheeks is 40,000 yen (excluding tax), and one treatment for face line is 30,000 yen (excluding tax).

Also, if there are no large scars and only redness remains, iontophoresis or electroporation that introduces vitamin C derivatives and whitening ingredients from the inside is effective, which regulates skin turnover. is.

In the case of leftover acne scars (scars), dermatologists use peeling and whitening agents to remove old keratin and soften the skin.

In any case, there are no cases where people in their 50s still have acne and are in pain. In that case, depending on the individual’s condition of redness and blemishes on the scar, it is also possible to divide it into several treatments, such as whitening care and plump scars, and combine treatments such as lasers and light. Therefore, it may be better to plan in a long span.

On the other hand, if you are not good at this kind of aesthetic medical approach, let’s work on home care with less stimulation patiently.

What other self-care can you do?

One skin care oil that is said to be effective for acne scars (scars) and scars is skin care oil such as Bio-Oil. Ingredients include derivatives of vitamin A and vitamin E. It is said that it has an antioxidant effect, reduces damage to the skin, and properly adjusts turnover.

Since it is an oil in the first place, it has a high moisturizing effect and softens the skin, so it is possible to prevent fine wrinkles caused by dryness.

It is also effective for spots called post-inflammatory pigmentation that can be formed on scars. Also, if you have pigmentation due to keloids or post-surgery scars, consult your doctor first.

In Oita Prefecture, there is a carbonated hot spring called Nagayu Onsen, which is rare in Japan.
