Why are acid scrubs better than grainy scrubs?
Scientifically proven ability of AHA, BHA, TCA acids to effectively remove the layer of dead cells from the skin surface and clean clogged pores. Meanwhile, scrubs with grains (mechanical particles) never exfoliate the skin as effectively as acids, they destroy the skin's protective barrier, which disrupts the skin's moisture balance, and can also sensitize and injure the skin. So, choose scrubs with acids because:- Acid peeling does not damage the protective skin barrier;
- Acid peeling does not mechanically damage the skin;
- Regular use of acids has additional benefits - it promotes skin renewal, collagen synthesis, can even thicken the epidermis, brightens, evens out skin tone, reduces pigment spots and skin flaking, treats acne, and can reduce wrinkles;
- In low concentrations, it is convenient and safe to use at home;
However, you should know the following facts about acids:
- Sun protection is mandatory when using acids, as the skin becomes more sensitive to the sun's effects - the outer layer of dead cells acts as a very low sun protection filter, say SPF 3-5.
- Certain acids can sensitize the skin, so we choose milder ones suitable for sensitive skin.
- Excessive use of acid-based products can acidify the skin's pH, so acid exfoliation should be used in moderation - only as much as necessary. It is important that this procedure does not become addictive.
- For some people, not necessarily those with sensitive skin, acids (not all) cause an unpleasant tingling sensation, but it goes away quite quickly.
- Some people are allergic to certain acids, but you can almost always rely on salicylic acid, which is suitable for sensitive skin, does not cause allergic reactions, and even has a calming effect.
What to look for when choosing a facial scrub?
· Acid concentration . In products intended for home use, the percentage of acids in the composition is limited. Of course, this is done for safety reasons. The maximum concentration of glycolic and lactic acid is 10 percent, salicylic acid - 2 percent. There is also trichloroacetic acid, but it is more often used by professionals. These acids are the most popular and effective when applying chemical peeling. · Product pH . This is very important! If the pH of the product is too high, the acid will not work as an exfoliant. The regulatory authorities of the cosmetic industry limit the lower pH limit; the pH of the product with acid must be at least 3.5, but for the acid to effectively remove dead cells and exfoliate the skin, the pH of the scrub must be no higher than 4.0. Therefore, when buying scrubs with acids, you need to look for manufacturers' instructions regarding the pH of the product. Without finding them, you will not be sure that the product is really effective. · Skin type . I recommend using different acids for different skin types or you can choose products with several acids. It is important to know that glycolic and lactic acids are more suitable for dry, normal skin with unclogged pores. These acids will remove the layer of dead cells, reduce flaking, brighten, even out the skin and its color. For oily and combination skin, deep pore cleansing is important, and only salicylic acid can do this. Therefore, for those with problems with clogged pores, acne, and excessive sebum production, I recommend using a scrub with salicylic acid at home quite often (3-4 times a week). It penetrates deeper, cleans the clogged pore itself, and also suppresses inflammatory reactions, and reduces redness. · Skin sensitivity . If you have sensitive or allergic skin and AHA acids (lactic, glycolic) are not suitable for you or cause allergies, use BHA (salicylic) acid - it will not only exfoliate the skin, but also soothe and have an anti-inflammatory effect.Sun protection
It is important to know that when using products with acids, it is necessary to protect the skin from the sun! Acids remove the small natural protective filter on the skin and make it even more sensitive to sunlight.After applying the AHA serum, my skin looks brighter and smoother the next morning. I really didn't expect such results so quickly.
