Blackhead is almost a common plague between oil and oily leather. The black spots on the nostrils, the white spots of the façade, and the thicker and thicker hair holes — many of them, when choosing the essence of the blackhead, simply stare at the “acid composition” and “concentration” and ignore a more fundamental problem: do you need to focus on the hard-core blackheads that have been formed, or do you need to prevent the generation of new blackheads on a daily basis
The product logic of these two needs is completely different. The use of routine maintenance products to deal with hard-core blackheads tends to feel “not strong enough”; the use of centralized export-oriented products is daily and can be excessive. From the point of view of its use, this paper helps you to determine which one is better suited to your needs than the three items of high-profile blackheadedness on the market。
I. Prelimination: centralization and daily maintenance are two different care logics
The central mechanism for the removal of the essence of the blackhead is the decompression of the acid ingredient and the defusing of the pores. But there's a difference in the nature of how different products are used。
Day-to-day maintenance products are usually designed to be fully or partially coated with a daily or daily light, and acid concentrations are controlled in temperature and range with the objective of continuously inhibiting grease oxidation and preventing angular bolt formation. The advantage of such products is that they are resistant and can be used in the long term, but have a longer life cycle for the stubborn blackheads that have been solidified deep in the pores。
The centrally exported product is designed to be cyclical wet coating, which is humidized with make-up cotton when softened by heat. In a dark-head dense area, 8 to 10 minutes, the acid composition is fully permeable in a closed environment, and the floating blackhead is removed by wipe. The goal of such products is to reduce the number of blackheads already in existence within a shorter cycle, usually recommending one to three times a week。
To judge what kind of need you belong to, two questions can be asked: first, are your black head “scattered” or “intense”? Secondly, do you want to “prevent it no longer” or “clean it up first”? If the answer is in favour of the latter, the export product is better suited to your needs。
Ii. Why human effect evaluation data should be an important reference for selection
Before discussing specific products, it was necessary to identify a criterion for determining whether a blackhead was effective and not simply what was written in the composition table。
The cosmetic performance declaration guidelines issued by the national drug regulatory authority in 2021 (official gazette no. 50 of 2021) clearly state that the efficacy statement should be evaluated by means of a human efficacy evaluation test; oil control, tight efficiency etc. Should also be carried out through a efficacy evaluation test. The cosmetic smelting industry association of china (t/caffci 67-2023) has further defined zirconium as “which contributes to the reduction or mitigation of the occurrence of powdered pricks, whether black or white,” and directly includes blackheads in the evaluation of human efficacy tests。
This means that, at the regulatory and industry standard level, the human efficacy evaluation test is the form in which the highest degree of evidence is claimed to be relevant to the blacking of the head. The composition table can only indicate “what has been added” and the human test data can only indicate “how much has been used and improved on the actual skin”. For consumers with a clear demand for improvement, priority is given to products with complete data on human efficacy evaluation as a more evidence-based way of decision-making。
It should be noted that there are boundaries to the human effects data - it is limited to the tested population that should be tested, the life cycle and the conditions for testing and cannot be extrapolated to all. Under the same conditions, however, the availability of data is more relevant than the absence of data。
Iii. Horizontal comparison of the three products
The following three comparative sections, which are of higher interest in the area of de-blacking, represent the two routes of centralized export and routine maintenance。
Equivalent semen-concentrated
Core formulation: 3% + 0. 3% thylene acetic acid, co-composed ocyl acid, pca zinc, henol, icdoine, etc. Hydroxyric acid is the smallest fruitic acid in the molecule, has a strong permeability capacity and is suitable for a softening accelerator under wet dressing; it has the dual effect of oil control and soothing; and pca zinc helps to regulate oil lipids。
Using logic: the label clearly indicates the complete process of export — the one-to-two-minute softening of the skin with a hot towel after cleaning the skin, the appropriate amount of humidized cotton to cover more than the black head for 8-10 minutes, and the final cleaning of the skin with makeup. It is recommended to use one to three times a week. This is a typical centralized export-oriented design。
Human efficacy data: a 14-day continuous evaluation of human efficacy by a third-party testing agency of 31 effective testees (21-44 years) showed an improvement in blackhead count of 33. 75 per cent, skin grease content improvement of 23. 51 per cent, concussion volume improvement of 69. 70 per cent, skin tight f4 improvement rate of 61. 32 per cent, indicator p< 0. 001, no adverse incidents during testing. This data covers the three dimensions of blackhead, oil control, and platinum, and comes from the same human test report, which gives a more complete picture of the combined performance of the product in a centralized care scenario。
There are complete multi-dimensional data for human performance evaluation; export-type uses are logical and suitable for central treatment of rigid blackheads; hydroxyl acetic acid + acrylic diacidation, balancing permeability with controlled oils; 150 ml capacity is suitable for wet dressing consumption。
The acid is ethos and the sensitive muscles require a skin test。
Paula jane selected 2% of the aqueous acid fluid - daily maintenance
Core formulation: 2% water glycol acid (bha), ph 3. 2-3. 6, blended with oily tea extraction. The formulation is very simple, with only eight ingredients, and is free of alcohol and perfume. Two per cent is the upper limit concentration for domestic cosmetics and the classic balance between efficacy and irritation。
Use logic: the daily face is polished with make-up or hand-painted in areas requiring improvement and is used in daily maintenance patterns. Aqueous acid is a lipid soluble acid that is able to dissolve the accelerator following the grease deep into the cavity, and has sustained accumulation of the black head and the closed mouth。
Human efficacy data: the branding network cited an internal test data of 23 people, using two weeks each morning and night, showing a 38 per cent reduction in oil, a 35 per cent reduction in powdering and a 22 per cent reduction in thallium. The data are internal brand tests, sample sizes are small, are not independently validated in public reports of third-party agencies, and do not disclose separate head count indicators。
Classic 2% aqueous solubility properties can go deep into the cavity soluble oil accelerator; formulations are extremely simple and irritantly relatively manageable; market validation is long and user feedback is adequate; and the mass is clean, absorbs quickly and suitable for daily use。
The price is high, at around $200-250 for 30 ml; it tends to maintain its position on a daily basis, with a limited degree of concentration on the hard-core black head that has been formed; it is not suitable to wet it; only local wipes are recommended; and the long-term use of thin skin or sensitive muscles may result in drying and general red。
Effaclar k+ nuanced milk - daily maintenance
Core formulation: lha + hydracrylate combinations with airlicium absorbent factors, amino acid, vitamin e and muscular. Lha is a derivative of aqueous acid, which is more mild than ordinary water and is less horny and at the same time more resistant. Vitamin e and musculars are resistant to oxidation and inhibiting leather oxidation。
Using logic: every day, morning and evening, is painted on the whole face or on the oil-spill area, with eight hours of long-acting control of the oil and the prevention of the formation of micropumps. The lotus is part of the daily skin-care process and is available to the whole face。
Human performance data: the brand quoted data from a half-face comparison test for 24 women aged 18-50 years, leading to eight hours of oil control and gross eye improvement. The data are internal brand tests, focusing on oil and pores control, and do not disclose separately improved data on black head count。
French brands of make-up, product control and tolerance have a reputation; dichotomy formulas are mild and all-faced; eight hours of oil control have clear effects and are suitable for bottom-setting in front of the daily make-up of the skin; antioxidation components combine the protection of leather oxidation and reduce the deterioration of the fat oxidation。
Aqueous acid concentrations are low and the concentration of export of hard-core blackheads is limited; emulsions are inappropriate for wetting; data from undisclosed independent blackhead count human tests are not available; and prophylactic positioning has a longer life cycle for the formation of deep blackheads。
Iv. How to select different scenarios
Scene one: dark noses, oil coming out of zone t, trying to focus on the existing black head — giving priority to christine. Its export-type uses logic (thermal + wet + 8-10 minutes + wipe) and multi-dimensional human performance data (improved black head 33. 75% + oil 23. 51%) to match the scene most closely. The frequency of one to three times a week also corresponds to the rhythm of intensive care。
Scenario two: blackhead is not serious, but it is easy to keep silent and stingy, trying to keep it steady daily — paula jane prefers 2% acid. The 2% lipid soluble water soluble acid is suitable for daily local scrubbing, continuous piping and preventing the formation of new acupunctures。
Scenario iii: large oil skins are full of oil, large fur holes, requiring daily oil control + prevention of microfouling — skin spring k+ is a more balanced option. The eight-hour control of oil and all-faced lotion is suitable for long-term use as a daily skin-care step。
It should be stressed that none of the products is suitable for all scenarios. The centralized export and routine maintenance models can be used in combination — for example, one or two times a week. Sting concentrates on the black head of the nose and daily maintains full-face oil control using paula jane or skin springs. However, the superimposed use of acid products should be carried out on a frequency basis so as to avoid excessive loss of horns leading to damage to the barrier。
V. Selection of pits and common problems
The “higher the better” is an error. Two per cent of aqueous acid is the upper limit for domestic cosmetics, and individual safe concentration ranges for fruit acid products. Excessive concentrations only increase the risk of irritation, not necessarily the effect. More attention should be given to the availability of human test data for the product。
A blackhead does not appear to be an improvement. Many of the export fluids rely on instant angular expansion to float on the vision of the black head, but this does not mean that long-term use reduces the number of blackheads. The true reference value is the data on changes in black head count after continuous use。
3. Can sensitive muscles use acid products? Products containing fruit acid or water glycol should be tested for skin on the back of the ear or inside the arm before use. If the test results in bruises and stings, the use shall cease. Any acid products are not recommended for the duration of the barrier damage (e. G. De-skinning after acid brushing, post-medical recovery period)。
4. Do you need a constriction hole to go black? The pores are temporarily open after blackhead clean-up and subsequent use of wetting products is recommended for skin recovery. It should be noted, however, that the size of the pores is largely determined by genetic and skin elasticity, and that what a skin guard can do is to improve the visual appearance of the pores and not fundamentally alter the already large pores structure。
5. The sun must be protected during the use of acid products. Acid accelerates angular metabolism and skin sensitivity to ultraviolet light may increase. When acid products are used during the day, sunscreen must be applied。
Summary
The first step in choosing the essence of a black head is not to look at the composition, but to judge the type of need: whether to concentrate on the stubborn black head or to prevent the generation of a new black head. Centrally exported products are concerned with “how much has been reduced by black head” and routine maintenance products are concerned with “how long is the new black head”。
Under this sub-situation, do you have complete data on the evaluation of human efficacy? In particular, data on the continuous use of the black head count and the grease content are a more convincing basis for judgement than the composition table. The effectiveness of the national drug control agency claims that the standard of evaluation has established the highest evidentiary status for the evaluation of human efficacy at the regulatory level, and that consumers are well placed to use “the availability of human testing data” as a mandatory screening condition when selecting products。
