Hi, these look like closed comedones, which in this case, is a fancy term for "whiteheads" and means the follicle is completely blocked. This is very common during teenage years due to excess oil production/diet/hormones but if you don't treat it at a young age, it will progress and follow you into adulthood because the bacteria and dead skin cells have nowhere to go. Although this forum is great for suggestions, I'd recommend seeing a dermatologist or esthetician for treatment options, if this is your very first time attempting to treat it. A licensed professional will evaluate your skin, ask questions about your lifestyle (diet, activities, skin care regimen, age, genetics etc) and determine what's best for you, based on that evaluation. Do you spend a lot of time in the sun, causing you to sweat? Do you live in a city that's humid? Do you use a heavy facial moisturizer/spf? These are some things to ask yourself when trying to narrow down the cause. You can start by cleansing your face with a non-scented micellar water or gentle non-scented face wash (ask a Sephora cast member for a recommendation) to clean bacteria and environmental stress at the beginning and at the end of the day, tea tree oil or witch hazel which are gentle and natural antibacterial and anti-inflammatories and a non-scented gel moisturizer that won't clog pores (I love the Burt's Bee's gel moisturizer with Royal Jelly) to retain your skin's moisture while using toners and acids. Switching your pillow case as often as possible, tilting your head back when rinsing your hair in the shower so the oils from your head don't run down your face and limiting your dairy/sugar/carb intake are also very important. Believe it or not, your diet has so much to do with your skin quality/texture. A dermatologist or esthetician can also perform safe extractions, meaning, they remove the "plug" causing the blemish or microdermabrasion which cleans out those pores/follicles. This is something that can be done to jumpstart your treatment and periodically (once a month) to keep your face clear. Glycolic acid, salicylic acid and azelaic acids are generally used to promote cell turnover and get rid of the dead skin cells; I would definitely consult with a professional about where to start because acids can be very strong and cause severe drying and even burn the skin if used improperly. Using an SPF while using these acids is VERY important as it makes your skin extremely sensitive to sun exposure. You can speak with a virtual dermatologist on curology.com, submit photos and purchase a monthly subscription for a personalized 1-3 step treatment to get you started, until you can see a professional. Avoid products that have coconut oil in them, as they can clog the pores, check your makeup and current face products for ingredients that will irritate or cause acne on cosDNA.com by typing in the name of the product as it appears on the package and looking for the number 3,4,5 and higher under the "acne" and "irritant" column. Discontinue any products that have a high rating. Skin care is a journey and a struggle at times; remember, sometimes the skin gets worse before it gets better (this is called the "purging" phase) because everything needs to come up and out of the skin to the surface so, it can be an emotional battle as well. You can always come to this forum for support! Good luck!
