Hi @MrsC103121 ! A good way to start a skincare routine is to figure out what your particular skin needs: what are your skincare goals and/or issues? What exactly do you want products to do for your skin? That'll help you avoid buying lots of products you don't need, regardless of what beauty influencer videos claim you need.
The Inkey List has a "Recipe Builder" at their site that recommends products in order of use. The Ordinary also has a "Regimen Builder" tool. My own skincare routine is a mix of various brands (including the 2 I just mentioned) because no single brand's entire product line works for me. But if you want to stick to just one brand, like The Inkey List, try their recipe builder and/or contact them for help.
The general order of products in a routine (note that only 3 steps are mandatory):
- Wash - this includes PM makeup removal and double-cleansing.
- Tone (optional step) - old school astringent pH-balancing toners aren't needed much anymore, now that many cleansers are less alkaline than soap. Some of us do use hydrating and/or skin brightening toners that aren't astringent or alcohol-laden. An essence can also be used here. (I'm sure some K-beauty fans will disagree but honestly, today's toners aren't much different from essences in terms of what they can do.)
- Exfoliate (1-3 times a week; optional step) - this is mostly a chemical exfoliant step. (Most physical exfoliants—scrubby cleansers, brushes, Foreo, terrycloth washcloth, etc.—happen during the wash step.) It's where you'd use an AHA, BHA, PHA, or enzyme exfoliating product. Some doctors argue that chemical exfoliation isn't necessary because the act of manually washing your face is a form of exfoliation, so... eh, whether or not you do this step depends on your skincare needs/goals and the other products in your routine.
- Treat (optional, depending on your skincare goals/needs) - what's in this step depends solely on your skin's needs. Could be a niacinamide serum, hydrating humectant serum, peptides serum, hyperpigmentation treatment, acne treatment (instead of or in addition to BHA), etc. The general "rule" is to apply products from thinnest to thickest consistency, but that's not a necessity. It really depends on the products in question. Example: I frequently apply an azelaic acid cream before liquid serums with no issues. For some folks, retinoids (retinol, retinaldehyde, adapalene, tretinoin, etc.) are applied in this step. Other folks with more sensitive skin like to apply retinoids after moisturizer to buffer the irritating side effects.
- Moisturize - make sure your skin's damp before you apply a moisturizer. This ensures your moisturizer's got some hydration to seal into your skin.
- Sunscreen (AM only) - broad spectrum, at least SPF 30, applied to ALL exposed skin, regardless of season or weather. If your sunscreen has at least one good moisturizing ingredient, it can double as your daytime moisturizer—so you could skin the previous step. You'll need to reapply sunscreen every couple hours throughout the day; it's not a "one and done" application product.
In addition to The Inkey List and The Ordinary, brands like CeraVe, La Roche-Posay, and Vanicream make some very good products that are reasonably priced. Depending on your budget, Paula's Choice is another option: they frequently have sales at their own site and they sell sample/travel sizes of several products.
