Dear Sir/Madam


Adagene Inc.


We have acted as Cayman Islands legal advisers to Adagene Inc. (the “Company”) in connection with the registration for issuance and sale by the Company of (i) ordinary shares at par value of US$0.0001 per share (“Ordinary Shares”), including Ordinary Shares represented by American Depositary Shares ("ADS(s)”), each ADS representing 1.25 Ordinary Shares, (ii) warrants to purchase Ordinary Shares or other securities of the Company ("Warrants"), (iii) units ("Units" and, collectively with the Ordinary Shares and Warrants, the "Securities"), or any combination thereof, in one or more offerings as contemplated by the Form F-3 Registration Statement (“Registration Statement”), to be filed by the Company under the U.S. Securities Act of 1933, as amended with the U.S. Securities and Exchange Commission (the "Commission") on or about April 26, 2022. The Securities being registered are for a maximum aggregate offering price of US$200,000,000. We are furnishing this opinion as exhibit 5.1, 8.1 and 23.2 to the Registration Statement.


For the purposes of giving this opinion, we have examined and relied upon the originals, copies or translations of the documents listed in Schedule 1.


In giving this opinion we have relied upon the assumptions set out in Schedule 2, which we have not independently verified.


We are Cayman Islands Attorneys at Law and express no opinion as to any laws other than the laws of the Cayman Islands in force and as interpreted at the date of this opinion.  We have not, for the purposes of this opinion, made any investigation of the laws, rules or regulations of any other jurisdiction.  Except as explicitly stated herein, we express no opinion in relation to any representation or warranty contained in the Documents nor upon matters of fact or the commercial terms of the transactions contemplated by the Documents.


Based upon the foregoing examinations and assumptions and upon such searches as we have conducted and having regard to legal considerations which we consider relevant, and subject to the qualifications set out in Schedule 3, and under the laws of the Cayman Islands, we give the following opinions in relation to the matters set out below.


1.The Company is an exempted company duly incorporated with limited liability, validly existing under the laws of the Cayman Islands and is in good standing with the Registrar of Companies in the Cayman Islands (the “Registrar”).

2.The authorised share capital of the Company is currently US$80,000 divided into 800,000,000 shares comprising (i) 640,000,000 ordinary shares of a par value of US$0.0001 each, and (ii) 160,000,000 shares of a par value of US$0.0001 each of such class or classes (however designated) as the Company’s board of directors may determine in accordance with the Memorandum and Articles.


3.With respect to the Securities when (a) the Board of Directors of the Company (the “Board”) has taken all necessary corporate action to approve the issuance thereof, the terms of the offering thereof and related matters; (b) the provisions of the applicable definitive purchase, underwriting or similar agreement approved by the Board have been satisfied and payment of the consideration specified therein (being not less than their par value) has been made; and (c) in the case of Ordinary Shares only, valid book-entry notations are made in the register of members of the Company, then such Securities as the case may be, will have been duly authorised and validly issued, fully paid and non-assessable (meaning that no additional sums may be levied on the holder thereof by the Company).
4.With respect to any Ordinary Shares which may be offered by Selling Shareholders (as defined in the Registration Statement) pursuant to the Registration Statement (the “Secondary Shares”), assuming any potential secondary offerings of Ordinary Shares made pursuant to the Registration Statement are limited to currently outstanding Ordinary Shares as at 13 May 2022 required pursuant to General Instruction I.B.3 of Form F-3, based solely on our review of the Register of Members, the Secondary Shares were duly authorised and are currently validly issued, fully paid and non-assessable (meaning that no additional sums may be levied on the holders thereof by the Company).


5.The statements under the caption “Taxation” in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects.


We hereby consent to the use of this opinion in, and the filing hereof, as an exhibit to the Registration Statement and to the reference to our firm under the headings “Legal Matters”, “Taxation” and "Enforceability of Civil Liabilities" in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.


This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.  This opinion is given solely for your benefit and the benefit of your legal advisers acting in that capacity in relation to this transaction and may not be relied upon by any other person without our prior written consent.


This opinion shall be construed in accordance with the laws of the Cayman Islands.


Yours faithfully
