I had minor purging the first week because I started using it everyday. As soon as I started every other day it settled and now I&#39;m back up to daily use with no issues and great results

I am always so impressed by the texture of Tiam&#39;s products and their Pore Minimizing 21 Serum is no different.

Similarly to the Cream in the same line, Niacinamide, Zinc PCA and Willow Bark extract are the star ingredients. 

The main difference between the serum and the cream, is that the serum contains a whooping 20% of Niacinamide.  There are just a handful of products on the market with such a high % of Niacinamide, the main reason being that studies have shown that Niacinamide between 5-10% will definitely have +ve benefits on the skin. Most people do not need more than this.

----- So then why should you try 20%? 

If you have been using niacinamide and feel that you are still struggling with oil control, enlarged pores due to excess sebum production and bumpy texture, after considering the rest of your routine, you may definitely want to consider this. 

My skin responds well to Niacinamide 10% serums, but within a month of adding this, I definitely saw an improvement with my pore control. The serum is very light-weight and can work in either your morning or night time routine.  I actually enjoy pairing this with my retinol or salicylic acid at night, while using the cream during the day.

BTW, Niacinamide works well with Retinoids, Vit C, Arbutin, Tranexamic Acid and Salicylic Acid, in case you are wondering about other parts of your skincare routine.

I recommend starting with 2-3 times per week. I had zero irritation using this every other day. Just like the cream, there is no added fragrance.  The white crystal sedimentation you see on the bottle neck of the bottle is also normal due to interaction with the air.

Do you think this will be helpful to your skincare routine?

The fragrance was pleasant but a little too much for me

This was an average cleanser for me. I love Some by Mi products but the scent on this one was a little too much for me. Other than that a little goes a long way so the product is economical and good for oily skin.

I am going through it really fast. The bottle will last 3-4 weeks with use twice daily. I wish the bottle was larger for the price but I will repurchase

I recently suffered from a Seborrheic Dermatitis flare. On the road to skin recovery, I have been very mindful of what products I am bringing back into my routine first. This ampoule arrived just in time for my current situation. The cosrx light propolis ampoule contains 83.25% of Black Propolis which is naturally:
- antifungal,anti-inflammatory and antibacterial 
- helps to heal stressed skin

🟡𝙁𝙊𝙍𝙈𝙐𝙇𝘼:
To the point, with just 11 ingredients, most of which are good hydration magnets and emollients, and no fragrance.

🟡𝙏𝙀𝙓𝙏𝙐𝙍𝙀:
While propolis is a waxy substance, this Ampoule from Cosrx is lightweight, has a lovely slip which makes it easy to spread on the skin, works well with other skincare products and has zero stickiness.

🟡𝙐𝙎𝙀 &amp; 𝙍𝙀𝙎𝙐𝙇𝙏𝙎:
I use this in my &quot;essence&quot; step, which is after toner and before other serums. The healthy glow to the skin is immediate on application and after two weeks it really has been a lovely addition for nurturing my skin back to health.

It is pricier than others but in my opinion, totally worth it. Definitely a cut above the rest.

I am a wash off mask girl so when I fall in love with a sheet mask it&#39;s a big deal. These are AMAZING at treating my acne prone skin, calming it and skin looks clarified,  hydrated,  bright and feels refreshed every time.

It is pricier than other Asian Sunscreens but worth it in my opinion

𝐦𝐚𝐤𝐞 𝐩:𝐫𝐞𝐦 𝐔𝐕 𝐃𝐞𝐟𝐞𝐧𝐬𝐞 𝐌𝐞. 𝐃𝐚𝐢𝐥𝐲 𝐒𝐮𝐧 𝐄𝐬𝐬𝐞𝐧𝐜𝐞 𝐒𝐏𝐅 𝟓𝟎+ 𝐏𝐀++++
I have been enjoying the make p:rem daily sun essence sunscreen alot but it makes me break my rules - I don&#39;t use moisturiser when using this sunscreen.😲😮 Don&#39;t shoot me! 😜 I&#39;ll tell you why it&#39;s ok with this one! This sunscreen is perfect for dry to normal skin types, but even with my oily skin, I didn&#39;t want to miss out on this.

𝐊𝐞𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬:
•	SPF 50+
•	PA++++ (very high UVA protection) 
•	Alcohol free
•	Paraben, Silicone and Sulfate free
•	Fragrance free (there is a scent which is probably from the natural plant extracts etc)
•	Eczema safe

𝐔𝐕 𝐅𝐢𝐥𝐭𝐞𝐫𝐬 (this is an all chemical sunscreen which contains newer stable and effective European and Asian filters. My skin does so much better with these than the traditional chemical filters used in western sunscreens).
•	Uvinul A Plus
•	Uvinul T 150
•	Bisoctrizole (Tinosorb M)
•	Iscotrizinol

𝐌𝐲 𝐭𝐡𝐨𝐮𝐠𝐡𝐭𝐬:
•	This is formulated with a 73% moisturizing essence base made of ingredients like Propanediol and Glycerin (hence I can definitely skip my moisturiser when using this one). 
•	While very hydrating and moisturising, it is still very lightweight and a pleasant experience to apply.
•	Although it is an all chemical filter sunscreen (see filters above), this does not irritate my skin or my eyes (and I apply my sunscreens on my eyes and around my eye area).
•	As expected, there is no white cast with this chemical sunscreen.
•	I probably won&#39;t wear this one under makeup because, while it is not &quot;greasy&quot;, it does leave a lovely sheen on the skin.
