PPM stands for “parts per million”. It is a type of measurement unit of concentration. It represents part of the total number in units of 1/1,000,000 (million). It is a unit that is more commonly used in skincare labs.
Korean companies use this measurement because if a product uses an ingredient name in the name of the product, they are required by law to disclose the concentration of the ingredient. They will often therefore use PPM or the %.
We’ve all heard that you should reapply sunscreen throughout the day but does the same apply to hydrating products as well?
The truth is, if your products are doing their job, i.e. hydrating your skin, you really shouldn’t need to apply them throughout the day. The only exception would be misting sprays, which can be good if you live in a really dry climate or are in a room with harsh air con or heating.
In Korea, we use humidifiers in our rooms and offices during the day to counteract the effects of hydration, especially in winter. My top product for re-applying hydration is d’Alba Piedmont’s White Truffle First Spray Serum.
Coincidentally this is also a fan favourite in some of Korea’s most popular makeup artist shops. Some of the big shops in Cheongdam dong (which are where celebrities often go to have their makeup done on shoots) have it on hand to use before photoshoots.
Despite being a popular ingredient in beauty products since the 1990s, there is little scientific evidence to suggest that the skin’s natural collagen content can be replenished through the use of topical skincare products containing collagen. This is mainly because collagen molecules are too big to be absorbed by the skin.
What is true however, is that collagen in skincare acts as a humectant(a water-binding ingredient). This is beneficial, particularly for dry and aging skin, as it helps plump, soften and smooth the skin. It also helps to properly hydrate it.
Other popular humectants include ingredients like hyaluronic acid. Rather than replacing the skin’s own natural collagen. collagen-infused skincare products instead work to moisturise, hydrate and nourish the skin.
Final verdict? There’s probably no need to spend a lot of money on a collagen product if that’s the only good ingredient in it, but it is a good option for people looking to hydrate and moisturise. Try APLB Collagen Ampoule Serum and APLB Collagen Peptide Moisture Cream.
The short answer is yes.
The main reason is that, not only is it skin too but the skin on your neck can be quite dry. Necks are constantly exposed to movement and they get more UV exposure than other parts of the body.
Because they are susceptible to wrinkles and discoloration it’s a good idea to apply your skincare products (and especially SPF) right down your neck as well.
My recommendation is to opt for a multi-purpose product that you can use on your eyes, neck and marionette lines – try APLB Collagen Propolis Eye Cream.
